Narrated Anas ibn Malik: A man who had the mark of yellowness on him came to the Messenger of Allah ﷺ. The Messenger of Allah ﷺ rarely mentioned anything of a man which he disliked before him. When he went out, he said: Would that you asked him to wash it from him. Abu Dawud said: Salam is not 'Alawi (from the descendants of Ali). He used to foretell events by stars. He bore witness before Abi bin Arafat to the visibility of moon, but he did not accept his witness.
