Amr bin al-Sharid narrates from his father, Sayyiduna al-Sharid (may Allah be pleased with him), about the Prophet (peace and blessings be upon him), that whenever he found a man lying on his face with nothing covering his buttocks, he would nudge him with his foot and say: "This is the most hateful way of lying down in the sight of Allah Almighty."
Ahmad recorded it, and its narrators are the narrators of the Sahih.
