Musannaf Ibn Abi Shaybah 12402 — The punishment of the grave and what

Sayyiduna al-Bara (may Allah be pleased with him) said: We went with the Prophet (peace and blessings be upon him) to the funeral of a man of the Ansar. When we reached the graveyard, and the lahd (niche in the grave) had not yet been prepared, the Prophet (peace and blessings be upon him) sat down, and we sat around him as though there were birds upon our heads. In his hand was a stick with which he was scratching the ground. He raised his head and said: "Seek refuge with Allah Almighty from the punishment of the grave."
