Hazrat Umm Hissain Ahmiyyah (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) delivered a sermon in the plain of Arafat while he had wrapped himself in a sheet, and said: Even if a slave of Abyssinian origin with a cut nose is appointed as your leader, listen to him and obey him as long as he leads you according to the guidance of the Noble Qur'an.
