Give brief orders; speeches that are too long are likely to be forgotten. - Abu Bakr

In the Name of Allah, the Most Beneficent, the Most Merciful. This is the (final) command of Abu Bakr ibn Abu Quhafah, which he writes as he is exiting this world of the Hereafter... a time during which a disbeliever comes to believe, a wicked-doer comes to have faith, and a liar tells the truth: Verily, I appoint over you Umar ibn al-Khattab as my successor, so listen to him and obey him... If he acts justly, then that is what I think of him and that is what I know about him. But if he changes for the worse (i.e., he begins to act unjustly), then for each person is that which he has earned. Goodness is what I wanted, and I do not know anything of the Unseen world. "And whose who do wrong will come to know by what overturning they will be overturned." Quran, Chapter 26, verse 227

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 wills; and the strong amongst you shall be weak with me until I have wrested from him the rights of others, if God wills. Obey me so long as I obey God and His Messenger. But if I disobey God and His Messenger, you owe me no obedience. Arise for your prayer, God have mercy upon you.

It is a matter of great shame that the birds wake up in the morning before you.
