Yahya bin Husain narrates from his grandmother that I heard the Prophet (peace be upon him) say: If even a slave is appointed as your leader who leads you according to the Book of Allah, then listen to him and obey him.

Yahya bin Husain narrates from his grandmother that I heard the Prophet (peace be upon him) say three times: "May Allah's mercy be upon those who shave their heads." The third time, people requested that those who shorten their hair also be included in the supplication, so the Prophet (peace be upon him) included them as well.
