„I have been given the authority over you, and I am not the best of you. If I do well, help me; and if I do wrong, set me right. Sincere regard for truth is loyalty and disregard for truth is treachery. The weak amongst you shall be strong with me until I have secured his rights, if God will; and the strong amongst you shall be weak with me until I have wrested from him the rights of others, if God will. Obey me so long as I obey God and His Messenger. But if I disobey God and his Messenger, ye owe me no obedience. Arise for your prayer, God have mercy upon you!“
— Abu Bakr First Muslim Caliph and a companion of Muhammad 573 - 634
As quoted in Muhammad: His Life Based on the Earliest Sources (1983) by Martin Lings, p. 344.
