I have been chosen caliph, though I am not the best of you. If I prove to be good, please help me. But if I prove to be to the contrary, then don’t hesitate to put me right. Truth means honesty; and lies mean dishonesty. The weak among you is strong before the law until he is redeemed from oppression and the strong among you is weak before the law until he abstains from oppression. As long as I obey God and His Prophet, you have to obey me. But if I become disobedient then you can disobey me.
The first day Abu Bakr R.A became caliph, he delivered this oration.
