Musannaf Ibn Abi Shaybah

Hazrat Abu Huraira narrates that the Messenger of Allah, peace and blessings be upon him, passed by a man who was lying on his stomach. The Prophet, peace and blessings be upon him, said: Surely, this is a way of lying down which Allah does not like.

Hazrat Yaish bin Qais bin Takhfah narrates that my father was among the Ashab-e-Suffah. He says: Once, while I was lying on my stomach in the morning, suddenly a man kicked me with his leg and said: "This is the way of lying down which Allah Almighty does not like." He says: I raised my head and saw that it was the Messenger of Allah, peace and blessings be upon him.
