From his (Adam’s) progeny Allāh chose prophets and took their pledge for his revelation and for carrying His message as their trust. In course of time many people perverted Allāh’s trust with them and ignored His position and took compeers along with Him. Satan turned them away from knowing Him and kept them aloof from His worship. Then Allāh sent His Messengers and series of His prophets towards them to get them to fulfil the pledges of His creation, to recall to them His bounties, to exhort them by preaching, to unveil before them the hidden virtues of wisdom and show them the signs of His Omnipotence namely the sky which is raised over them, the earth that is placed beneath them, means of living that sustain them, deaths that make them die, ailments that turn them old and incidents that successively betake them.
