The present world has been created and made subject to the law of cause and effect. So, if an individual is beset by adversity, it is clearly due to his own shortcomings. However, it sometimes happens that a man commits a sin, yet remains unaffected by its baneful outcome. All these events happen in the world in order that man should learn a lesson from them. When he sees that whatever people receive is commensurate with their deeds, he should infer that, in the Hereafter also, everybody will be rewarded according to his deeds. Similarly, when he sees that somebody has been guilty of a lapse, yet goes unpunished, he should learn the lesson that God is Merciful and Gracious, and that if a man turns towards Him, He, in His Mercy, will save him from the consequences of his shortcomings. If a man’s Faith is deep, he comes to the point of discerning a picture of the Hereafter in the events of this world.
