Divine wisdom behind diseases

People who live in the societies of ignorance continually make plans for the future and hope these plans proceed as they desire. This being the case, an unexpected disease or some accident throws their life into complete disarray, since such incidents were not incorporated into their future plans. While they are enjoying good health, many of them never think that such incidents-even though it happens to thousands of others every day-could happen to them.

That is why, when confronted with such unexpected incidents, the ignorant people immediately become insolent towards their Creator. They contradict the fact of destiny and say, "Why has this happened to me?" for people who are far from possessing the morality commanded in the Qur'an, tend not to put their trust in God at times of sickness or accident, or to seek the good in what befalls them.

Such people, who do not grasp the reality of destiny, assume that it is merely the viruses or microbes that cause a sickness. Similarly, when they are involved in a traffic accident, they assume it is the driver of the other car that caused the accident. However, the truth is otherwise. Each disease-producing agent, such as a microbe or bacteria, or anything that causes harm to man, are, in actuality, creatures created by God as a cause. None of them are "haphazard" causes; they all act under the control of God. Man is vulnerable to microbes because God wills it so. If a man becomes seriously ill due to a virus, it happens because this is within the knowledge of God. If a car hits a person, leaving him disabled, this is also an event that has come into being by God's Will. No matter how one strives to avoid them, he can never alter the course of these happenings; not even a single one of them. He cannot remove a single moment from his destiny, because, fate is created as a whole. For a person who submits himself to the All-Mighty God, and who trusts in His infinite wisdom and mercy, an accident, disease or another adversity, is a temporary trial that leads to ultimate bliss.

It is the good moral qualities that a person adheres to in such circumstances that is important. Diseases and accidents are the incidents in the face of which believers have the opportunity to show forth their patience and good morals, and through which they can draw nearer to God. In the Qur'an, God discusses diseases while relating the importance of patience through such times:
 

... Those with true righteousness are those who believe in God and the Last Day, the angels, the Book and the prophets, and who, despite their love for it, give away their wealth to their relatives and to orphans and the very poor, and to travellers and beggars and to set slaves free, and who attend to their prayers and give alms; those who honour their contracts when they make them, and are steadfast in poverty and illness and in battle. Those are the people who are true believers. Those are the people who go in fear of God. (Surat al-Baqara: 177)

A person confronted with a physical dilemma must keep in mind that it is a trial for him, and that it is only God Who brings about diseases and their cures. This is the reasoning necessary for maintaining a proper moral attitude. A person benefits from thinking about the good and divine purpose in the disease he suffers, or an accident he might be involved in, even though he may not be able to grasp them immediately. It may be that he must go through a temporary difficulty, but that, in the hereafter, as a servant who has wholeheartedly submitted himself to his Lord, he will be rewarded with infinite bliss.

We all need to keep in mind, however, that it is essential to recognize this fact deep in our hearts and to maintain high morals immediately after being confronted with a similar incident. For this end, we need to know that all diseases are created for a purpose. If God were to will it, a person would never become sick or feel pain. But, if a person is afflicted with such a trial, then he must be aware that it is for a purpose, helping him to grasp the transience of this world and the infinite might of God.
