Yahya related to me from Malik from Ishaq ibn Abdullah ibn AbiTalha from Anas ibn Malik that his grandmother, Mulayka, invited theMessenger of Allah, may Allah bless him and grant him peace, for foodand he ate some of it. Then the Messenger of Allah, may Allah blesshim and grant him peace, said, "Get up and I will lead you in prayer."Anas said, "I stood up and took a woven mat belonging to usthat had become black through long use and sprinkled it with water,and the Messengerof Allah, may Allah bless him and grant him peace,stood on it. The orphan and I formed a row behind him, and the oldwoman stood behind us. He prayed two rakas with us and then left."
