The lotus, a radiant and graceful aquatic plant with a magnificent ability to repel dirt, has been the inspiration behind a range of self-cleaning and dirt-repelling technologies. Now a registered trademark, the “Lotus Effect” promises a future filled with objects that rarely, if ever, need washing. Finally, this means owning bathroom mirrors that unfog itself and shirts that shrug off ketchup and coffee.

And the earth, We have spread it out like a couch; and how excellent We are in spreading it. (Adh-Dhariyah, 51:48)

The factory of the universe and the guesthouse of the earth are so pure and clean and so untainted and fresh that … if … the act of cleansing is not attributed to the Creator of the universe, then … [e]ither all the creatures would have a share in the universal act of cleansing… or there would have to be a consultative committee the size of the universe in order to decide and regulate all those acts together… This is impossible not just once, but hundreds and thousands of times over. (4)

Have you ever come across a “stinky forest”? How about a “messy desert”? These questions are primarily posed as rhetoric since various means of sanitation is ubiquitous in nature (Stinky forests and lakes actually exist only thanks to pollution—a modern problem introduced by human intervention via misconduct of technology) where Lotus Effect is only one of the mechanisms contributing to the steady “house-keeping” in nature.

In muddy waters, the lotus plant stands out with its ever-clean leaves making it a symbol of purity in Asian cultures. Moreover, lotus leaves keep dry under even the heaviest monsoon rain. Such seemingly ironical feats are accomplished by capitalizing on a principle named after the plant itself: The Lotus Effect.

The Lotus Effect

At first sight, the cleansing of the leaves by the rainfall seems utterly trivial. However, the cleaning of the lotus plant (Nelumbo nucifera) by the downpour is not something to be taken for granted. Curiously, when raindrops encounter the lotus leaf, they adopt an almost perfectly spherical shape, resembling ball bearings, and start rolling off the surface carrying away all the dirt (Figure 1). Easier said than done, the lotus plant always keeps pristine, even at the microscopic level.

In the early 1970s, soon after the electron microscope (which can yield vivid images of the ultra small details that are at length scales on the order of a billionth of a meter) became commercially available, German botanist Wilhelm Barthlott (of University of Bonn, Germany) started imaging plants using the newly discovered technology. Sample preparations for electron microscopy normally demanded tedious cleaning procedures since even a speckle of dust could ruin the portrayed landscape at such minuscule scales. To Barthlott’s surprise, some plants apparently were “self-cleaning”: They required very little (or sometimes none whatsoever) cleaning for detailed inspection with the microscope and the lotus plant was a prince of these (1). Further intrigued by the fact, Barthlott looked at the lotus leaves through the electron microscope to find out what renders the lotus plant remarkably competent to repel even the tiniest dirt.

Water’s love-hate affair

Before delving into the secrets for lotus plant’s sanitation, let’s look at the interaction of water with other materials. At the molecular level, the electrical charges are unevenly distributed across a water molecule (i.e. water is highly “polar”) which becomes entangled in a love-hate type of relationship with other materials: Some materials “love” water tending to maximize their interaction with it, whereas others “hate” it, trying to avoid their encounter with water as much as possible.1 To put things in perspective, we can immediately tell from everyday experience that oil is “water-hating” since oil and water do not mix, while sugar is “water-loving” because sugar can dissolve in water without much effort.

Macroscopically—that is, one can immediately realize by touching a lotus leaf—the lotus leaf surface feels waxy, and should therefore be water-hating. However, the waxiness is not enough to equip the lotus plant with its unusual capabilities to remain clean since the lotus leaf is not alone among plants in its leaves’ surface waxiness. Indeed, there is more to the lotus leaf’s curious surface properties than that, a property which was first recognized by Barthlott under the electron microscope.

Super water-hating surfaces

When Barthlott looked at the lotus leaf, besides its spotlessness in the microscopic sense, the leaf surface was decorated with numerous bumps a few micron sizes each (a micron is one millionth of a meter). Such bumpiness served to enhance the water-hating aspect of the surface making it “super water-hating,” corresponding to a contact angle that is close to 170 degrees. As a result, water encountering the lotus leaf surface rapidly beads up forming a nearly spherical shape (akin to the scenario when one drips water on a hot cooking pan) and drops roll off the surface even with an ever-so-slight inclination of the leaf. Apparently, a rolling water droplet is much more effective in picking up the surface dirt than one that is merely sliding, and all the surface debris is thus wiped off.

Although discovered first in the lotus plant, the super water-hating surfaces are serving a passive yet effective means of cleaning for animals like butterflies, dragonflies and other insects that are not able to clean all their body parts actively. For plants, preventing the coverage of their leaves by water (or other contaminants) is important to maximize the exposure to sunlight which would otherwise cause reduced photosynthesis. Another great biological relevance of surfaces of such nature for all these creatures is that it provides protection against the growth of pathogens by keeping the surface dry at all times.

Inspirations from biology for technology

There are ever-growing biologically inspired technologies, so-called biomimetics, and the lotus effect provides a nifty example. Unfolding the mystery behind lotus’ exceptional competence in self-cleaning, Barthlott patented the idea of artificially manufacturing microscopically-raised, water-repelling surfaces to mimic the lotus leaf. “Lotus Effect” is now a registered trademark which underlies commercial products such as self-cleaning windows and fabrics, as well as a dirt-repelling paint. Other applications that are waiting around the corner are: swimsuits that stay dry for days allowing prolonged underwater excursions, coatings on metals to avoid the deposits of marine bioorganisms which would enable up to 40% reduction on fuel consumption by decreasing friction (2). Metal coatings will also find applications to prevent ice formation on plane engines alleviating their wear-and-tear (3).

Apparently, lotus does not collect dirt, but only patents.

Note

1 Contact angle is a metric for the water propensity of a surface. Water drop displays a higher contact angle (hence lower contact area) on a water-hating surface when compared to a lower contact angle (hence higher contact area) on a water-loving one.

Everywhere I look, I see citizens polluting, communities mistreating and nations exploiting the earth.

I watch them as they misuse and abuse this sacred place, as if it was theirs.

What they fail to remember is that this earth is the same earth the first man and woman called home. It is the same earth countless prophets, saints, and scholars called home. It is the same earth my Ottoman ancestors called home. It is the same earth my country’s natives, the Aboriginal people, called home.

But I could almost see this earth diminish before my eyes. My heart aches with uncertainty of what lies ahead.

What have we left to offer the future generations? What have we done? What have we become?

Divine cleanliness

Everything God created in this world and beyond has perfect order and balance, for He is the Most Powerful and All Wise. So it cannot be He who is responsible for the world’s current state of affairs.

This earth is like a hotel, a guesthouse which is continually filled and emptied by the living and dead. Despite this constant entry and exit, this guesthouse remains totally pure and clean. There is nothing unnecessary, nothing exists without having any benefit or purpose, and not a random piece is put out of place.

If it was not for this remarkable cleaning, in a short amount of time, thousands of animal and plant species would have been suffocated on the face of the earth.

God’s orderliness is everywhere the eye reaches.

Carnivorous animal species clean the seas by gathering up the corpses of other sea-creatures that die every day by the millions, preventing the sea from becoming polluted.

Ants collect the corpses of tiny creatures and small particles and fragments of bounty, preserving them from waste and uselessness.

Flies clean away poisonous substances and microbes which breed diseases that are invisible to the naked human eye, thus preventing the spread of many contagious diseases.

His command is obeyed everywhere by everything, from eyelids cleaning the eye and flies brushing their wings.

Therefore, there is magnificence and harmony in every creation in every corner of the world. With varieties of beauty spread in a myriad of colors and forms, it is so splendid that imaginations are pushed to the limit when trying to imagine anything more beautiful.

It is such a pity that this wonderful world, which God has bestowed upon humans to observe and study free of charge, is no longer given any more care than is given to a heap of junk.

“How deplorably and awkwardly we have treated plains and residential places, which we have changed into deserts and heaps of ruin. How deplorably and gracelessly we have treated seas and rivers, which we have polluted. Again, how deplorably and awkwardly we have treated air and water, and fields, forests, and gardens, which we have made unfavorable to any life. Truly, by changing this Paradise-like world to a hell, how deplorably and awkwardly we have treated ourselves!”

In our eagerness to “progress” and “develop,” we have lost sight of the finite and delicate nature of our world and of humanity’s place in it. So it is when humans improve the condition of this world whose order they have destroyed and polluted, and restore it to its prior balance and beauty, only then will they be able to live a healthier and happier lifestyle.

Guardians of the Earth

The origins of global environmental problems lie in humankind’s deliberate rejection of the physical laws governing environmental management and a persistent disobedience to God’s spiritual laws.

“And do good as God has done good to you. And desire not corruption in the land. Indeed, God does not like corruptors.” (Quran 28:77)

The Quran and the teachings of Prophet Muhammad, peace be upon him, contain instructions to assist humanity in preserving its environment. In the Quran God declares, “It is He who has appointed you viceroys (guardians) in the earth” (6:165). Through this verse it becomes evident that humans have a special place in God’s scheme. They are more than friends of the Earth; they are its guardians.

Prophet Muhammad, peace be upon him, lived up to this verse best as a guardian of the earth. He was an “environmental pioneer” who lived with the philosophy that there is a fundamental link and interdependency between all natural elements and that if humans abuse one element, the natural world as a whole will suffer the direct consequences.

For instance, the Prophet pointed out the many benefits in planting trees which he said will last until the Day of Judgment. He said, “If the Hour is imminent and anyone of you has a palm shoot to plant in his hand and is able to plant it before the Hour strikes, then he should do so and he will be rewarded for that action.”

Furthermore, the Prophet recommended and warned that shaded spots where people could rest and spaces under fruit trees should not be dirtied. He also emphasized that there should be no spitting on roads and places of worship, and objects that could injure people should be removed from the roads and put to one side. All of these principles are essential for every person to implement in ensuring a healthy environment and in respect to protecting and keeping the environment clean.

The Quran also emphasizes not harming other living creatures on earth. God declares, “And there is no creature on or within the earth or a bird that flies with its wings except that they are nations (communities) like you.” (6:38)

Recent statistics show that over 60,000 animal species have gone extinct, over 4 million hectares of forests are lost, around 1.8 billion liters of water are used up, and around 10 million tons of toxic chemicals are released into our environment by industries each year. These are massive amounts of waste and destruction that humans have brought upon themselves.

The environmental devastation encapsulating this planet is thus a direct result of these physical laws being broken. These statistics illustrate the results of our law-breaking catching up with us.

The Ottomans: Sultans of Sympathy

The Ottoman era was a period during which an extreme emphasis was placed on the regulation and protection of the environment, such that had legally enforceable consequences. This meant that there was zero tolerance towards any misuse of the environment.

It is possible to see the value, importance, and respect given to the environment by the Islamic world during fifteenth century through the will of the great Ottoman Sultan Mehmet, Fatih the Conqueror. The will reads:

“I, the conqueror of Istanbul, humble servant Fatih Sultan Mehmet, donate 136 shops which I personally and rightfully own in Taslik suburb of Istanbul with the following conditions:

I have assigned two persons for every street in Istanbul to be paid from the profit earned from these shops. These persons are to walk along these streets at specific times of the day with a bucket in their hands which contains limestone and coal powder. They are to conceal any spit found on the streets with these powders and be paid 20 akçe (Ottoman currency) per day.

Furthermore, I have assigned 10 surgeons, 10 doctors, and 3 nurses. They are to walk through the streets of Istanbul on certain days of each month, knock on each and every door and find out whether there are any sick people in that household. If there are, they are to treat them. If this is not possible at the time, they are to be transferred to Darülaceze (nursing homes/hospitals) and be treated there.

Additionally, the families of the soldiers who are fallen martyrs and the poor people of Istanbul are to be fed in the soup kitchen which I have built. However, those who are not able to personally come and eat there or collect their food will be provided with alternative service. Their food is to be sent to their homes in concealed containers after sunset without it being seen by others.”

Another royal document regarding environmental care comes from sixteenth century Sultan Süleyman the Magnificent titled Nisan-i Hümayun. Some important points to note in this document include:

“All homes, shops, and their surroundings are to be kept clean or to get cleaned. Those in charge should identify citizens who litter and get those who are responsible to clean their own litter.

Owners of oxcarts should not disturb local residents by leaving their animals near houses or courtyards. They are to collect and dispose of the dung from their animals to appropriate places outside of the city. People are to be prevented from throwing the carcasses of horses, sheep, etc. onto the streets. Those who refuse to comply with this rule are to be punished publicly.

Used water containing detergent and soap are not to be thrown out onto the streets. No individual has the right to prevent these rules from being implemented and will closely be monitored by law enforcement agencies.”

It is clearly evident that in royal documents like those mentioned above, the leaders took necessary precautions and showed sensitivity towards the implementation of the matters regarding the protection of spiritual and physical wellbeing of the people and the cleanliness of public places.

Animal rights are a contemporary issue that came to public attention only quite recently. Unfortunately, in today’s society, many governments are still struggling with human rights issues, let alone dealing with animal rights.

Ottoman sultans implemented legal measures on the protection and the treatment of animals. In doing so, the care and proper treatment of animals were bound by legal measures and are not left to the individuals’ own judgment.

The Ottoman Empire was known for its vakýf, or foundations, which were first set up to meet the needs of certain groups of people within society but later became an integral part of the Ottoman lifestyle. The most interesting of these vakýf were those dedicated to animals. These foundations were places where generous people would donate certain amounts of money to bakeries and butchers so that they could provide bread and meat for street animals.

Moreover, the sultans did not just stop at providing food for animals, they also made sure that if these animals fell ill, there were specialized hospitals for them to be treated in and looked after.

Ricaut, a British clerk who worked at the British embassy in Istanbul during the Ottoman period (d. 1700) said how impressed he was by the respect and value the Ottoman people had given animals and the importance they had shown towards their nutrition and protection.

“There were not only people, but also cats and dogs that ate from the soup kitchens. In some cities buildings were made for cats, foundations were established for their nutrition, and expenses were paid for the allocation of servants to meet the needs of these animals.”

Aboriginals: The Key to Land Management

Until quite recently the human race, whether in small self-governing native communities or vast empires, functioned instinctively within natural, unwritten boundaries. When these old civilizations died, the forest and natural environment just grew over them. They left no rubbish, pollutants, or waste.

Similarly, Aboriginal tribes of Australia moved around their land for tracking shifts in the availability of important resources. Their respect for the native flora and fauna meant using techniques to ensure their survival.

They actively managed their land through prescribed burning regimes handed down from their ancestors. Aboriginal people burnt to hunt, to promote new grass, to make their land easier to travel through, to clear their land of spiritual pollution left after a death, to create firebreaks for later in the dry season, and for a variety of other reasons whose sole aim was to “bring the land alive again.”

They also had such deep respect for the animals on their land that, for instance, they would slaughter a kangaroo to eat only if the total number of kangaroos in a specific area had reached a certain amount. So until then, they could not touch the kangaroos even if it meant staying hungry and finding something else to eat. Their overall respect for the plants and animals of their land is one that was extremely sacred, one they felt liable to take care of and pass on in good condition to the generations to come.

Conclusion

Today, however, man has much more to offer the world, intellectually and technologically, when compared to the past. Despite having the upper hand in areas such as science and technology, the environment is still struggling and suffering. Who has control over whom? Why is it that tribes, clans, and empires in the past with little advancements had more control over the environment, and today with all the technological breakthroughs, people are still struggling?

Sadly, the harmony that the Prophet promoted between man and his environment has been lost. As we face the effects of chemical pollution caused by industrial wastes, visual pollution caused by rubbish dumping; noise pollution caused by unnecessary sounds, and thought pollution caused by pointless and disorganized overflow of information, it is perhaps time for the world community as a whole, regardless of faith or background, to look into Prophet’s teachings and address the current environmental crisis wisely.

The fundamental solution to these crises lies in humankind respecting the physical laws and embracing the spiritual laws designed by God.

Only then can there be true health, happiness, and healing.

More specifically, groundwater represents 98% of the available fresh water on earth. The contamination of groundwater has increased significantly due to industrial developments over the last century. To illustrate how the modern human has had an impact on the environment, let us look at some numbers: In the United States alone, yearly 100 million tons of hazardous waste is generated and 4 million tons of toxic chemicals are released into streams; in addition, 1.2 million tons of toxic waste are emptied into landfills and 1.5 million tons are injected into deep wells for disposal. Again in the United States, of the 2 million underground storage tanks in gas stations, 450,000 are leaking gasoline and petroleum products to the subsurface. If these numbers do not impress you, remediation costs for contaminated sites in Europe are expected to exceed $1.5 trillion in the near future. These are only some of the impacts of heavy industrialization of which we are aware. The contaminants that are released into the environment severely threaten drinking water, agricultural, and surface waters.

The pollution process of the subsurface environment is ironically simple. Leaks from various contamination sources seep into the groundwater from where they travel and infiltrate the soil with which they come in contact. Contaminated soils and sediments slowly release these pollutants, which over long period of time have become a continuous source. Of course, all these contaminants can potentially cause cancer or have detrimental effects on the ecosystem or on human health. To give an example of how these pollutants easily spread around the globe, in a recent study of dairy products that were collected from countries all around the world, the same type of organic contaminant (PCB:

Polychlorinated Biphenyls) was found in those products that, for the most part, originated in the USA, although the usage and production of this contaminant has been banned since 1976. How have these pollutants managed to persist in the environment and travel all the way from USA to the rest of the world, even as far as Australia? There are several ways this can be done; first the released contaminant volatilizes into the air and travels, through atmospheric depositions of large quantities onto the grass that is eaten by the cow. Another way is that a fish swimming in contaminated fresh water is caught and becomes food at a dairy farm. This research exemplifies how the pollution of the environment can affect us, regardless of where we live on this planet.

It seems like a very gloomy picture though, if nobody is going to take any action against the contamination or clean up the toxic chemicals from vulnerable targets like drinking water sources or terrestrial lands. There are, of course, many precautions that have been undertaken to clean up the environment. This article is about one of the interesting ways in which we utilize microorganisms to clean up contaminated groundwater or drinking water.

It sounds a little strange for engineers to be dealing with bacteria that naturally exist and utilize them in cleaning up the environment. But this is what they are doing, using a technique called bioremediation, wherein natural microbes become stewards for destroying the pollutants in the environment. The simple technical description of bioremediation is the intentional use of the biodegradation process to eliminate environmental pollutants that have been intentionally or inadvertently released. The biodegradation used here is the microbial transformation process of toxic chemicals into nontoxic forms and sometimes mineralization into inorganic elements like carbon, oxygen and hydrogen.

This transformation, which is essentially a process of destruction, first requires the presence of microorganisms. These microorganisms almost always exist in nature, unless there are harsh conditions that prevent microbial growth. The microorganisms use inorganic or organic contaminants as their nutritional and growth source in the life cycle. For example, a commonly encountered organic contaminant, benzene, is composed of six carbon atoms and six hydrogen atoms. During the degradation process, the microorganisms synthesize enzymes that stimulate the breaking down of benzene into carbon dioxide and water or sometimes the simple elements of carbon and oxygen. These enzymes ease the reactions that produce cellular energy and the building blocks for the synthesis of new cells. In essence, the contaminant serves as a nutrient – food – so that the microorganism can continue its life.

The electron acceptors

During the process in which the microorganism feeds on the contaminant (the degradation process), the key issue is the electron acceptors, the complementary part of the chemical reaction that occurs during the biodegradation process. During the breaking down of the large organic molecules into small elements, excess electrons are released into the environment and therefore an electron acceptor is required to maintain the chemical equilibrium and continue the reaction mechanism. This necessity for oxygen or iron dioxide resembles the need for oxygen in our liver to break down the complex molecules that occur during energy production and new cell generation. The process is as simple as this: we breathe oxygen to live and so do microorganisms. Oxygen molecules act as convenient electron dumps for bacteria that usually lie near the soil surface. Depending on the electron acceptor types, degradation reactions are categorized as aerobic (using oxygen) or anaerobic (using nitrate, manganese, iron and sulfate as electron acceptors). Humans can only inhale oxygen, but most insects can utilize other molecules, like iron oxide or sulfur as well.

Moreover, in order to have a successful clean up, scientists need to satisfy chemical and nutritional requirements and this is challenging for engineers. As these electron acceptors are not always readily available, engineers supplement the electron acceptors in the contaminated environment by methods like pumping air into the ground. Sometimes the microorganisms that are necessary to degrade the potential pollutant do not exist and the engineers must first inject the bacteria so that they can consume the pollutants as food.

Geobacter

One of the microorganisms most frequently studied for its degradation potential for organic and inorganic contaminants is Geobacter metallireducens, or the geobacter. Since it was first discovered, more than 20 years ago, researchers at the University of Massachusetts have been studying this incredible creature; however, they admit that there are many things that they still do not know about it. The geobacter was the first organism found to oxidize organic compounds to carbon dioxide using iron oxides as the electron acceptor. In other words, the geobacter gains its energy by using iron oxides (a rust-like mineral) in the same way that humans use oxygen. The main nutrient for the geobacter can be organic or inorganic pollutants for, and it breathes iron oxide in the way the human inhales oxygen. The geobacter can consume soil and groundwater contaminants like benzene and the gasoline additive MBTE, even in an oxygen-free environment. The geobacter, which has been found almost everywhere, even living in the dental spit-sinks, also flourishes in uranium-contaminated sites, converting soluble radioactive material to a material that is insoluble in groundwater, therefore making it easier to isolate for cleaning up. At present the geobacter is being put to work in actual clean up projects. As our understanding of the functioning of the species has improved, it has become possible to use this information to modify environmental conditions in order to accelerate the rate of contaminant degradation.

More interestingly, researchers have discovered that the geobacter spits out unwanted electrons into the circuit while consuming contaminants for energy. The geobacter exhales electricity through 20 to 30 hair-like structures, just 3 to 5 nanometers in diameter, to its surroundings. Although there is hardly enough microbe-produced electricity generated to solve the world’s energy problems, a fuel cell measuring a cubic meter would generate 2 kilowatts, and some engineers are talking about powering sewage treatment plants with a type of geobacter that harvests off the sewage itself. Just to give an idea about the direction of future research, researchers are now working on a selected gene of the geobacter. The gene that limits electricity production will be modified so that electricity production can be boosted during the degradation process. Given that, it would not be surprising if there were technology that created energy while cleaning contaminated soil or groundwater.

Clean water is a basic need for every human being, and it is our moral obligation to work as stewards for the environment; the first thing we must do is to stop contaminating the planet. However, we are faced with resources that have been previously contaminated. As one result of an increasing sense of responsibility toward nature, we are at a point where we can use natural microorganisms or plants as clean-up tools. Although mankind harshly contaminates the environment while creating an industrial and technological world, it is quite ironic that we still rely on the marvels of such divinely ordained solutions to sustain life.

This means that the One Who looks after the universe does so very well. Its Owner sweeps, cleans, and orders the vast universe and Earth as though they were small rooms. In relation to the size of the universe, there is no dirt or rubbish. Indeed, considering the size of the universe, its cleanliness and tidiness are remarkable.

If some people do not wash themselves or clean their small room for a month, they become extremely dirty. That is to say, the cleanliness, purity, and luminosity of the Earth arise from a continuous, wise, and diligent cleaning. If it were not so, in one year all of the 100,000 animal species on this planet would have choked to death.

Also, the debris of the planets and the heavens, which manifest life and death, and of satellites and stars would have smashed not only our heads and those of animals, but also the head of the earth itself. They would have rained down on our heads rocks the size of mountains, and driven us away from our homeland in this world. However, a few meteorites, as a warning, have fallen on this planet but have not broken any heads.

Furthermore, the corpses of 100,000 animal species and the debris of 200,000 plant species each year on our planet resulting from the alternations and struggles of life and death would have so dirtied the land and the sea that conscious creatures, rather than loving and delighting in our planet, would have felt disgust and aversion and fled to death and non-existence.

Just as a bird cleans its wings with ease and a scribe cleans his or her pages, so are the wings our planet, the birds of the heavenly bodies, and the pages of the Book of the Universe cleaned and made beautiful. This is true to such a degree that those who do not consider the infinite beauty of the Hereafter and do not think with belief become lovers of this world’s cleanliness and beauty. They worship it.

The Earth and the universe display the greatest manifestation of the Divine Name of the Most Holy (Quddus). Not only do meat-eating cleaners of the seas and eagles of the skies obey the commands proceeding from that sacred cleansing, but those cleansing officials that gather up corpses, like worms and ants, also do so. Just as red and white blood corpuscles flowing in the body obey those sacred commands to cleanse the body’s cells, so does breathing purifly and cleanse the blood.

As eyelids obey the command to cleanse the eye and flies to brush their wings, so do the atmosphere and the clouds obey the same command. Wind blows upon the particles of dust and soil settled on the face of the earth and cleans it. The sponge-like clouds sprinkle water on the garden of the earth and becalm the dust and soil. Then, in order not to dirty the sky, the wind quickly collects the earth’s rubbish, withdraws, and hides itself with perfect orderliness. It displays the beautiful face and eye of the skies as swept and polished, all sparkling and shining.

All stars, elements, minerals, and plants obey the command to clean, as do all particles and atoms. They pay attention to cleanliness within the astonishing upheavals of change and transformation. They never congregate anywhere unnecessarily and get in the way. And if they somehow become soiled, they are quickly cleaned, for they are impelled by a hand of wisdom to acquire the cleanest, neatest, and most shining states, and the most beautiful, pure, and subtle forms.

Thus this single act of cleansing, which is a single truth, is the greatest manifestation of the Greatest Name, the Name of the Most Holy, which shows itself throughout the universe. Like the sun, it shows itself directly to far-seeing and broad-sighted eyes as the Divine existence and Unity together with the Most Beautiful Divine Names.

It has been established with decisive proofs in the Risale-i Nur that since the act of ordering and order manifest the Names of Sapient and All-Wise; the act of weighing and balance manifest the Names of Justice and All-Just; the act of adorning and munificence manifest the Names of Beauteous and All-Generous; the act of sustaining and bestowal manifest the Names of Sustainer and Most Compassionate-as each is a single truth and a single act, they demonstrate the necessary existence and Unity of a Single Being. In the same way, the act of purifying and cleansing manifest and display the Name of the Most Holy, and demonstrates, just as the sun does, the existence of the Necessarily Existent One, and, just like daylight does, His Unity.

Just as these wise acts of ordering, balancing, adorning, and cleansing point to a Single Maker by reason of their unity of kind in the universe, so do most of the Beautiful Names. Indeed, each of the 1,001 Names has its greatest manifestation in the universe. The act proceeding from that manifestation points to the Single Unique One with clarity and decisiveness in relation to its extensiveness.

The self-evident truths and single acts that illuminate the universe and make it smile, like the universal wisdom causing all things to conform to its law and order, the comprehensive munificence that adorns all things and causes them to smile, the all-embracing mercy that makes all things pleased and happy, the universal provision of sustenance that nurtures and gives pleasure to all things, and the life and the giving of life that connects each thing with all things and makes each thing benefit from, and to some extent own, all things point to a single All-Wise, All-Generous, and All-Compassionate One, a single Sustainer, a single Ever-Living Giver of Life as plainly as light points to the sun.

If those hundreds of extensive acts, each of which is a clear proof of God’s Unity, are not attributed to the Single Unique One, each necessarily becomes impossible in hundreds of respects. For example, let alone such self-evident truths and single evidences as wisdom, providence, mercy, sustaining and giving of life, if only the act of cleansing is not attributed to the Creator, then the following becomes necessary:

• All creatures connected to this act of cleansing, from particles and flies to the elements and the stars, would have to know and consider the adorning, balancing, and cleansing of the vast universe and would act accordingly, or

• Each would have to possess the sacred attributes of the Creator of the world, or

• Each would have to be present at a consultative meeting the size of the universe in order to regulate the equilibrium of the adorning and cleansing of the universe and its incomings and outgoings.

Moreover, innumerable particles, flies, stars, and other elements of creation would have to attend this meeting. Hundreds of such impossibilities would have had to occur so that the universal, comprehensive, and exalted adorning, purifying, and cleansing seen and observed everywhere could exist. It is not impossible only once, but millions of times over.

If daylight and the imaginary miniature suns reflected in all shining objects on the planet were not attributed to the sun and were said to be something other than the manifestation of the sun’s reflection, it would be necessary for the actual sun to be present in all fragments of glass, drops of water, and snowflakes glistening on the earth’s surface, and even in all particles of air, so that the universal light could exist.

Thus, wisdom also is a light; all-embracing mercy is a light; adorning, balancing, ordering, and cleansing are each an encompassing light in the sense that they are rays of the Pre-Eternal Sun. So, see how misguidance and unbelief have entered a bog from which there is no way out! See just how ridiculous is such a view. Say: “Praise be to God for the religion of Islam and complete and perfect belief!”

This exalted, universal cleansing that keeps the universe clean is the manifestation and requirement of the Divine Name of the Most Holy. And just as the glorification of all creatires looks to the Name of the Most Holy, so does the Name of the Most Holy require the cleanliness of all of them. It is because of this sacred connection of cleanliness that a hadith states 1: “Cleanliness is a part of belief,” 2 thereby deeming it to be a light of belief. And the verse: “Indeed, God loves those who turn to Him constantly, and He loves those who keep themselves pure and clean” (2:222) shows that cleanliness attracts God’s love.
