Allah has created everything according to His divine wisdom, and has rendered many things to man's service. Clearly, many things in the universe, from the Solar System to the ratio of oxygen in the atmosphere, from the animals that provide us meat and milk to water, have been created to serve man. If this fact is recognized to be evident, it follows that it is illogical to think this life has no purpose. Definitely, there is a purpose to this life, explained by Allah as follows:
Only a minority of humanity understand this purpose of Creation and lead their lives thereby. Allah has granted us life on Earth to test whether or not we will conform to this very purpose. Those who sincerely serve Allah, and those who rebel against Him, will be distinguished from one another in this world. All those blessings (his body, senses, property...) given to man in this world, are a means by which Allah tests him. In a verse of the Qur'an, Allah relates the following:
Man's duty in this world is to have faith in Allah and the Hereafter, to conduct himself in compliance with the commands of the Qur'an, to observe the limits set by Allah, and to try to earn His good pleasure. The continuing trials of this life over time reveal those people who are committed to accomplish these tasks. Because Allah demands a true and sincere faith,-which is the kind of faith that is not attainable only by saying "I believe"-man must demonstrate that he has true faith in Allah and His religion, and that he will not swerve from the right path despite the cunnings of satan. Similarly, he must demonstrate that he will not follow the unbelievers, nor prefer the desires of his own self over Allah's pleasure. His response to the events in his life will reveal all these qualities. Allah will create certain hardships, during which man must show patience, in order to expose the degree of his dedication to faith in Allah. This fact is stated in the Qur'an as follows:
This being the case, disappointment in the face of difficulties would not be the right response to allow oneself to have. Such difficulties may be great ordeals or just trivial daily problems. A believer must consider all such circumstances as part of the trial placed upon him, place his trust in Allah, and conduct himself in compliance with His pleasure. In a verse of the Qur'an, those difficulties placed upon the believers are related as follows:
The Prophet Muhammad (may Allah bless him and grant him peace) also reminded the believers of this, by saying, "Whoever accepted it [Allah's trial], will enjoy Allah's Pleasure and whoever is displeased with it, will incur Allah's Displeasure." (At-Tirmidhi)
Not only will difficulties, but also blessings in this world serve to test man. Allah tries man with every benefit He bestows upon man, to see whether or not he will be thankful. As well, Allah creates many circumstances through which man adopt a certain attitude. In the midst of these trials, man may formulate a decision, either in compliance with Allah's pleasure, or his own soul. If he recognizes such an incident to be a trial from Allah, and conforms his conduct accordingly to earn Allah's pleasure, then he succeeds in his test. However, if his decision is in accordance to the dictates of his own soul, it will both be a sin, which he will greatly regret in the Hereafter, and a source of anxiety in this world, as it troubles his conscience.
Indeed, Allah creates everything that happens in this world as a trial. Those events considered to be mere "coincidence" or "bad luck" by the ignorant, are actually circumstances created according to the great subtleties of a divine plan. Of this, Allah gives the example of Jews who broke the Sabbath, tempted by an abundance of fish:
The Jews may have thought that the fish came forth to them on a Saturday by "coincidence," but, the event was predetermined as a trial for them by Allah. As this case makes clear, there is a divine purpose and a test in every occurrence in life. All that befalls a believer has been determined in order that he keep this notion in mind, and that he try to succeed at his test, and adopt a form of behaviour that is in compliance with the consent of Allah.
