وَإِن يَمْسَسْكَ اللَّهُ بِضُرٍّ فَلَا كَاشِفَ لَهُ إِلَّا هُوَ ۖ وَإِن يُرِدْكَ بِخَيْرٍ فَلَا رَادَّ لِفَضْلِهِ

Death testifies to the fact that man is completely powerless in this world. Death proves all those things false, on the strength of which man opts for the way of arrogance and denial of God. Death introduces man, on the one hand, to his helplessness and on the other to God’s majestic power. It shows that in this world there is nobody who has the power to grant benefits or inflict harm. If a man has a mind capable of learning lessons from events, then the event of death is enough to reform him. It makes a man a perfect worshipper of God. A time comes for every man when, helpless, he surrenders himself to death. Similarly, it is not within the power of any man, whether it concerns benefit or harm, to cause things to happen as he wants. He receives the desired benefit in any case; and remains safe from undesirable harm in any case. This state of affair shows that man is a powerless creature: he lives in a world where there is some Being who rules over him.
