It has been narrated on the authority of Yahya bin Husain who learnt the tradition from his grandmother. She said that she heard the Holy Prophet ( صلی اللہ علیہ وسلم ) delivering his sermon on the occasion of the Last Pilgrimage. He was saying: If a slave is appointed over you and he conducts your affairs according to the Book of Allah, you should listen to him and obeey (his orders).

This hadith has been transmitted on the authority of Shu'bah with the same chain of transmitters, and he said:" a negro slave".

In other versions of the above tradition, the wordings are" an Abyssinian slave." and" a maimed Abyssinian slave".

Another version of the tradition does not qualify the slave with the epithets" maimed,"" an Abyssinian" but makes the addition:" I have heard the Holy Prophet ( صلی اللہ علیہ وسلم ) (say this) at Mina or 'Arafat."

It has been narrated on the authority of Yahya bin Husain who learnt the tradition from his grandmother. Umm Husain. He said': I heard her say: I performed Hajjat-ul-Wada' in the company of the Messenger of Allah ( صلی اللہ علیہ وسلم ) . He said a lot of things (on this occasion). Then I heard him say: If a maimed slave is appointed a commander over you the narrator says: I think she said:" a black slave" who leads you according to the Book of Allah, then listen to him and obey him.
