Sayyidah Urnm Husayn Ahmasiyah reported that she heard the sermon of Allah’s Messenger (SAW) during the Farewell Hajj. He was wrapped in his cloak which he had drawn from his armpit. She said : I saw the flesh of his shoulder shining. I heard him say, “0 you people! Fear Allah, and even if a Black with a split ear is made your ameer, listen to him and obey him provided he governs according to Allah’s Book.
[Muslim 1298]
