سنن أبي داود

This is transmitted by Shu'bah through a different chain of narrators. This version adds: He ('Ammar) said: He (the Prophet) then blew it and wiped with it his face and hands up to elbows or up to the forearms. Shu'bah said: Salamah used to narrate (the words) "the hands and the face and the forearms". One day Mansur said to him: Look, what are you saying, because no one except you mentions the (word) "forearms".
