O people! I have been put in charge over you, but I am not the best of you. If I act well, then help me, and if I act badly, then put me right. Truthfulness is a trust and lying is treachery. The weak among you is strong in my sight until I restore his right to him, Allah willing. The strong among you is weak in my sight until I take the right from him, Allah willing. People do not abandon jihad in the way of Allah but that Allah afflicts them with humiliation. Shamelessness does not spread in a people but that Allah envelops them in affliction. Obey me as long as I obey Allah and His Messenger. If I disobey Allah and His Messenger, you owe me no obedience.
(Sira Ibn Hisham)
