Sayyiduna Anas bin Malik (may Allah be pleased with him) says: We were present at (the burial of) a daughter of the Messenger of Allah (peace and blessings be upon him), and the Messenger of Allah (peace and blessings be upon him) was sitting by the grave. I saw his eyes shedding tears, and he said: "Is there any man among you who did not commit (anything) last night?" Sayyiduna Abu Talhah and Sayyiduna Abu Dharr (may Allah be pleased with them both) said: I, O Messenger of Allah. He said: "Then go down into her grave." Fulayh said: I think he meant sin.
