The caliphate was only for Adam, peace be upon him, and not for any other race of the world, because God Almighty created him in his own image. The caliph must appear in what he appointed as caliph in the form of his caliph, otherwise he would not have a successor among them. So he gave him the command and the prohibition and called him the caliph and made the pledge of allegiance to him by hearing and obedience in the good and the bad, the hardship and the ease. God Almighty commanded His servants to obey God and His Messenger and to obey those in authority among them. So the Messenger of God, may God’s prayers and peace be upon him, combined the message and the caliphate, like David, peace be upon him. God stipulated his caliphate from God in the Almighty’s saying, “Then judge between the people with truth and the most beautiful caliphate of Adam, peace be upon him .”
