Man observes that a serviceable animal like the camel is obedient to him. The sky in all its majesty is well disposed towards him. The earth, without any effort on our part, is subservient to our interests. All these phenomena remind a thoughtful man of God and the Hereafter. Those who derive the nourishment of remembrance from these arrangements of the world have established their entitlement to God’s eternal bounties, while those who have remained lost in forgetfulness and neglect, have proved that they deserve to be deprived of every kind of bounty—forever.

Calling people to God aims at exhorting people through peaceful persuasion, to make them realize their Creator, the one and only God; to understand the purpose of their creation; the coming of the Hereafter, of their accountability to their Creator, etc. The purpose of this exhortation is to awaken souls from their slumber. It is to put a lost person on to the right path leading towards God. It is to awaken man’s insight so that he begins to see glimpses of God in the signs of the vast universe. It is to unveil the Creator in the mirror of His creation.

Man passes through two sets of circumstances in the world—sometimes finding or receiving things and sometimes losing them. Both eventualities, meant to gauge human reactions to different conditions, are for the purpose of putting man to the test. If the individual starts to boast when he receives something and acts negatively when things are taken away from him, he has failed the test.
