After he began to call his people to belief, the Prophet had to face all kinds of torment during his peaceful mission for thirteen years in Mecca. After numerous grievous incidents, he had to leave his town and reluctantly immigrated to Medina. From most people’s point of view, the Meccans were absolutely to be declared as “the enemy”-or “the other.” However, the Prophet did not behave inimical to anyone. He always treated people humanely, no matter what lethal traps they set for him. He never failed to extend his tender hand with a candid clemency and compassion. Even during many inexorable combats, he always prayed to his Lord, chiefly for those who smashed his helmet off, broke his tooth, and left his face covered with blood in battles like Badr and Uhud. Not only did he hinder his followers from bearing any oppugnant attitude against their merciless foes, he also blocked maledictions and imprecations to any adversary, even those who, for instance on the day of Uhud, had ripped the bodies of nearly 70 beloved ones into pieces beyond recognition with an incredible brutality.

Although his opponents were bloodthirsty and yearning for war, his sword was never besmeared by red hot blood; he never killed anyone. He did not represent anything other than loving compassion in the world.

He never broke off his previous social connections. He did not approach anyone with a bias. He always held the door open in order to mildly flatter their vanities. He never hurt anyone’s pride deliberately. While his sworn enemies took the gloves off for any opportunity to assassinate him, he treated everyone amicably by taking into consideration the potential positions they would likely to hold in the near future. Because he knew that every individual had a respectable essence, he thought the most appropriate action was to awaken this divine kernel. He took action in this direction, though horrid provocations did not cease, and he did that with a worthy perseverance.

Glad tidings

The Prophet dealt with every one of his opponents with utmost care, and he took very strategic measures not to destroy them but to conquer their hearts.

Giving the glad tidings of a coming peace, the following verse was revealed right after the Battle of the Trench:

(When you obey God in His commands and prohibitions,) it may be that God will bring about love and friendship between you and those of them with whom you are in enmity. God is All-Powerful, and God is All-Forgiving, All-Compassionate. (60:7)

Peace was so close, just at their threshold. Having received this good news, the Prophet initiated immediate action by demanding to marry the daughter of Abu Sufyan, who was then the political leader of the Meccans. Establishing bonds of kinship with him would be a plausible step in order to eradicate hostility. Umm Habiba, Abu Sufyan’s daughter, was among the group of Muslims who had fled the Meccan torture and sought refuge in Ethiopia. However, her husband died there, and she was left alone with her child without any protection. By marrying her, the Prophet would not only save this devoted Muslim woman from despair and honor her, but would also form a connection with Abu Sufyan that would not be possible by any other way. This marriage was realized soon, and afterwards everything changed dramatically.

Abu Sufyan, who was one of the staunch enemies of the Prophet until that day, could easily enter the Prophet’s home to visit Umm Habiba, his daughter. Now, Abu Sufyan could learn more about Islam through his daughter Umm Habiba. He began to realize soon that Muslims were not as he had believed. In a short period of time, the difference in Abu Sufyan’s attitude became more and more obvious. He turned out to be more moderate, more cautious, and more candid in reciprocal dialogue attempts.

Prominent figures of Mecca, Khalid ibn al-Walid, Safwan ibn-i Umayya, Suhayl ibn Amr and Ikrima ibn al-Jahl were exerting pressure on Abu Sufyan to take drastic actions against believers. Despite all of their intolerable pressure, Abu Sufyan resisted their aggressiveness, having realized that they were the ones who were unfair, not those on the Prophet’s side.

Making peace

Even in the most critical conditions he did not give up. Despite all the provocations of evil-doers and his own fellow tribesmen’s objections, he made agreements with his crucial adversaries and fulfilled peaceful commitments with them.

The radical change of Abu Sufyan was an explicit hope for others. The Prophet tried his best to take advantage of every single opportunity to get in touch with any of them.

After his immigration to Medina, the economic and social conditions of Mecca had gradually deteriorated. The Meccans were suffering from drought, famine, hunger, and misery. For sure, he could not have remained indifferent to this heart-rending situation. He sent them food and other needed aid; he literally inundated them with an immense benevolent contribution on the back of hundreds of camels. But, unfortunately the Meccans rejected all of it. Then he sent all the aid directly to Abu Sufyan. Afterwards Abu Sufyan distributed everything to the poor and needy Meccans.

The Prophet those days gave weight to free commerce and trading with other communities, particularly with Meccans. He knew that business trading was an excellent opportunity to get in touch with others. Thus they could have found so many new ways to maintain peaceful relations.

Regrettably, all the peaceful attempts made by God’s Holy Messenger were either repelled or responded to with brutal violence by the Meccans. They once attacked a Muslim tribe in the pitch dark of midnight and slaughtered 23 civilians in a village near Medina. By committing this crime, the Meccans also violated the Hudaybiya peace treaty.

Following this brutal attack, the Messenger of God sent envoys to Mecca, offering them various options to solve the problem peacefully, rather than an immediate retaliation: he asked them to pay the blood money and cut their relations with other warring tribes that participated in this crime. Failing to obey these conditions would mean the Hudaybiya treaty was violated as well as a declaration of war. But the Meccans refused every amicable offer. The only option left for the Prophet was to march to Mecca. Realizing that they would not be able to resist, some of the eminent Meccans fled in confusion to distant towns of the Arab Sahara. God’s Messenger sent someone in pursuit of every missing Meccan. Umm Haqim, Ikrima’s wife, who had fled all the way to Yemen, went after him. She dared all dangers on the way to find her husband, another relentless enemy of the Prophet and the son of Abu Jahl, and to introduce him to the Prophet’s mercy. Umayr ibn Wahb, once a hitman hired by Safwan ibn Umayya to kill the Prophet, went after Safwan twice, reaching him in Jeddah en route to Ethiopia, and convinced to him to return to Mecca. Suhayl ibn Amr was brought back by Abdullah, his own son whom he tortured for years. He wrote letter after letter to Wahshi, who had murdered Hamza, the Prophet’s uncle, and invited Hind, who had hired Wahshi for this murder, to come in peace and that she was forgiven. The Prophet called them back home promising to forgive all their past assaults and guaranteed their protection. Mecca became a land of peace and serenity, thanks to his efforts and merciful invitation.

The Prophet’s immense forgiveness is an example for us today as to how we should engage with past atrocities. It is a message of self-reformation that teaches us that we can subdue feelings of revenge and hatred and build a society in compassion and love.

I, the protective system that you call the “immune system,” am divided into different groups and sections, each of which has its own area of expertise. Just like a military unit, each of my groups has to be partially or fully trained before it begins life in my system so that it can properly fulfill its defensive function. “Soldiers” in this protective troop work according to what expertise they have and the type of “enemy” (alien microorganisms) they encounter. Some are equipped with heavy weapons against tough enemies; some produce a special poison with which they kill their enemies by injecting it into their bodies, some work like a waste disposal, smashing up the dead bodies of the enemies, and some of them eat the alien intruders alive when they attack your body. Others produce raw material to arm your body, some turn that material into weapons, some work as defenders, some are signalers, some are rangers and some are equipped with a special intelligence which allows them to recognize the previous invaders and destroy them more easily at their future encounter. In this intelligence system, which works like an information center, the soldiers check the dangerous invaders and remember their previous experience with them. Then, they develop a strategy to fight against those invaders. If the enemy is known well, the defense against it will be easier.

Now, using this analogy, I will talk about your enemies and the features of my soldiers that are placed in your body to fight against them. However, I have to remind you of something first: as you know, every army has to have a top commander. Similarly, there is someone who has placed such a perfect system like me in your body, someone who has boundless knowledge and power, and has no one else superior to Him or has no one to receive orders and instructions. That is our Lord God Almighty. Since He knows very well what kinds of enemies you will face, He has created me with all my troops so that you can be defended against those enemies.

The enemies of your body are germs, which enter your body through different passage ways, including digestion, respiration, excretion and the skin. “Germ” is a general term referring to many kinds of micro-organisms. Some of them are bacteria, some are fungi and some are viruses. Your body needs different special tactics to defend against each group of germs and my soldiers are quite talented in those tactics. I have to be always watchful against germs coming from outside. Not only that, but I also have to be careful about inner enemies, that is, the cells in your body which suddenly turn into “terrorists” becoming harmful and spoiling the system. You call those cells “cancerous.” It is a great challenge for me to cope with those cells because they originate from among your very own cells and they know our tactics very well. Nevertheless, with God’s help, we can defeat them. However, when too much stress and anxiety weaken me I might miss some of those cancerous cells, which will grow and become tumors. In fact, cancerous cells develop much more in number than is commonly known. But my soldiers constantly check every single cell that is formed in your body and try to see whether it is normal or not. As soon as they discover a cancerous “terrorist” cell, they try to quickly destroy it. However, some cancerous cells are disguised like a wolf wearing a sheepskin so that they can avoid detection. My soldiers make rounds and check the cells from outside by only looking at their skin. Thus, they can be manipulated. All of your cells, including those with germs or cancer, contain protein with a special code which identifies the cells as being yours. When my soldiers encounter our fellow cells carrying those coded proteins, they release them. But the enemies who do not carry this code (or password) are immediately caught and destroyed. When we have diseases like cancer, however, the cancerous cells may evade our “rounds man” because they know this password. Sometimes the opposite may happen: my soldiers get confused and cannot identify their fellow cells despite carrying the right password, assume that they are enemies and start to attack them. These types of diseases, called Autoimmune diseases, emerge with a quite complicated mechanism which is a puzzle even for me! For example, during rheumatoid arthritis, which is among the many long-lasting and unrecoverable diseases, my soldiers attack and gradually destroy the tissues like cartilage, cardiac muscle, eye lenses, and the tubes of the kidneys with which they share a body. In fact, when we are created as a whole system (when you are only an embryo in your mother’s womb), some of my soldiers make an agreement with the other cells of your body, announcing that they will forever stay friends with them, will show tolerance to them and will only attack the enemies. But, somehow this agreement is broken later; my soldiers do not obey me anymore.

Now it is time for my group of soldiers to introduce themselves:

The most general term by which we are identified with is white blood cells or leukocyte. We appear approximately 6,000 to 7,000 times in each cubic millimeter of human blood. The other blood cells, which are called red blood cells (erythrocyte) are red in color; it is for this reason that we are called white. Since blood vessels can reach to the remotest edges of the body, we roam around the body through those vessels and look for work to do. Of course, not everyone can do everything. So, we are first divided into two sections. The cells in the first section contain microscopic granules, so they are called granular leukocyte. The cells in the second section do not contain such granules, so they are called agranular leukocyte. Those sections are divided into groups among themselves. The first section has three groups: neutrophils, eosinophils and basophils. The second section has two groups named monocyte and lymphocyte.

Eosinophills: You may not know much about these soldiers that make up 12% of the whole protective body. However, during allergic reactions and diseases caused by parasites, the number of these soldiers increases. They complete the effect of the antibodies produced against the antigens. Some chemical substances like histamine appear as a reaction to antigens, such as itchiness, rash, and swelling. Eosinophils reduce the effects of those substances and the symptoms.

Basophils, which are the least in number, make up the 0.5% of the body. Those soldiers are present mostly in the scars that are healing or in highly infected areas. The granules inside basophils contain two very important substances called heparin and histamine. Histamine helps expand the blood vessels and accelerates the release of active substances within me from the blood vessel walls, enabling them to reach to the affected area. Heparin also prevents the blockage of blood vessels because of blood clot.

Lymphocytes of the second section are the group of soldiers which goes through special training and has expertise in many subjects. They make up 20-25% of the soldiers in my system. Those soldiers detect antigens and germs and remove them from the body. Every soldier has a detector which identifies a certain antigen. Therefore, in your blood, there are millions of lymphocyte soldiers, which are different from each other and do not have a pair. For any antigen of a germ, you will definitely find a lymphocyte that finds and kills it. Those soldiers can be grouped according to their appearances, as small, medium, and large lymphocytes. Each group has different special features. We can also divide them according to their maturation and training process as B-lymphocytes and T-lymphocytes. Although both of them originate from stem cells in the bone marrow, T-lymphocytes mature in the thymus before they move to the other lymph tissues such as the spleen, liver, and tonsils (Thymus is a gland in the chest that talked about itself in the previous issue). B-lymphocytes, however, mature in the bone marrow, and go directly to the tonsils, appendicitis, spleen and other lymph tissues. When the T lymphocytes mature in the bone marrow, they acquire different new features. Some of them work as T helper cell, some work as natural killer T-cells and some work as suppressor T-cell. A helper T-cell, which is triggered by an antigen that is specific to it, secretes lymphokines, which makes B-cells produce antibodies. Among those lymphokines, interleukin-2 activates the natural killer T-cells, which kill the infected cells. The killer T-cells do not bind directly to an antigen. Rather, they secrete a substance that kills the infected cell after joining with the antibodies that were previously bound to the infected cells. On average, T-cells live 2-4 years; some, however, live more than 10 years. Today, the defense mechanism of the T-lymphocytes creates an issue in terms of organ transplantation. If, for some reason, a foreign organ (a kidney or heart, for example) is transplanted into the body, the T-lymphocytes attack that organ immediately. Those “headless” soldiers do not know that the body really needs that organ and try to eliminate it, therefore, leading to transplant rejection or tissue incompatibility. The T-lymphocytes treat the foreign organ the same way as they do to the cancerous cells: they attack and try to destroy it. For this reason, the immunologists are trying to discover medicines that will help them control the soldier T-lymphocytes whenever they need to be stopped.

Dear Peter, have you ever thought about how all this happens? While you have no idea about a germ that might enter your body, those memory cells, which are placed in your blood with a boundless compassion by our Creator, remember an enemy that they saw years ago, and begin to make weapons right away. Since those cells are devoid of reason and consciousness, to operate them there has to be Someone with a great knowledge and will.

The lymph nodes are production centers for the lymphocytes found at some particular places in the body. They resemble variously sized military headquarters. The lymphocytes are produced mostly at infection sites, which are the little lymph tissue groups located under the epithelium that lines along the walls of the digestive tube, respiratory track, and the bladder. When fighting with bacterial infections the lymph nodes swell and enlarge as much as 1–2 cm. In addition to the lymph nodes that extend through the lymph vessels, the areas such as nape, groin and the axilla (underarm) also contain lymph nodes. If you get an upper respiratory tract infection, the lymph nodes at your tonsils and neck areas become swollen. If you get a urinary track infection the nodes in your groin area become swollen. As for digestive track infections, it is the responsibility of the lymphocytes in your appendix to fight against germs. Some scientists view this organ, which is an extension of the cecum (the blind gut), as a “dead” piece of intestine. Both the appendix and tonsils are quite useful organs that produce lymphocytes in normal circumstances; they are not some useless remnants. For that reason, it is not right to remove them when it is not really necessary. However, we have to remember the proverb that says, “We salt the food so that it does not smell bad; but, what do we do if the salt itself smells bad? Then, we have to get rid of the salt.” Similarly, in some bodies where my system is weak and so is lymphocyte production, those areas become home to germs and you have to remove them.

Other than the soldiers of the immune system, several organs in your body have their own ways of protecting your body. Those organs do not have soldiers like in my system; theirs are like a “civil defense.” Chief among those are your skin which works as a natural barricade against the entrance of the germs, the mucous membrane that lines along the walls of your mouth and inner nose, interferon which is a substance produced by your cells against viruses, and an antibacterial substance called lysozyme which exists in your tears and sweat. Therefore, sweating, crying, and runny nose are not things to be ashamed of; they are only the protective systems that have been naturally placed in your body by our Lord God.

Dear Peter, I think I should stop here although there are still so many features of me that you have to discover. After all, beneath all diseases and deaths you will find disorders related to me. The biochemical processes in which many of my soldiers operate are not exactly known yet. If those are revealed, doctors will likely succeed in healing many other diseases. However, sooner or later you will reach the destined end: death. No creation can be immortal; there will definitely be a problem and you will have to leave this world, wherein you are only a guest. If you carefully contemplate the works of art in your body, in the hereafter you will have solved the riddle of the delicacies of those works. Of course, everyone’s time of death is unknown. Therefore, in this limited time, give your organs their due and give thanks to the God Almighty who gave you those gifts. Live according to His will, and always remember to glorify Him. Goodbye, Peter! May you and your troop be healthy!
