Musannaf Ibn Abi Shaybah 28384 — A man lying flat on his face

Ya'ish bin Qays bin Tikhfah says that his father (may Allah be pleased with him) was one of the People of the Suffah. He says: While I was lying on my stomach at the pre-dawn time, a man suddenly pushed me with his foot and said: "This is a way of lying that Allah Almighty hates." He says: I raised my head and saw that it was the Messenger of Allah (peace and blessings be upon him).
