Abu Salih narrates: I was present with the noble wife of the Prophet (peace be upon him), Sayyida Umm Salamah (may Allah be pleased with her). A young man from among her relatives came to her who had long hair. He stood up and began to perform prayer. When he was about to go into prostration, he blew first. So Sayyida Umm Salamah said: Do not do this, because the Prophet (peace be upon him) said to one of our black boys, "O Rabah, (during prostration) make your face dusty."
