Musannaf Ibn Abi Shaybah 12184 — Reports on burial at night

Abu Yunus al-Bahili says: I heard an old man in Makkah, who was originally a Roman, narrating from Sayyiduna Abu Dharr (may Allah be pleased with him) that a man used to circumambulate the House saying, "Awwah, awwah." Sayyiduna Abu Dharr said: "I went out one night (and saw that) the Prophet (peace and blessings be upon him) was in the graveyard, burying that very man, and he had a lamp with him."
