Musnad Ahmad 32:1439

Yunus and Surayj narrated to us, they said: Fulayh narrated to us, from Hilal ibn Ali ibn Usamah, from Anas ibn Malik, who said: We attended the funeral of a daughter of the Messenger of Allah, may Allah bless him and grant him peace, and the Messenger of Allah, may Allah bless him and grant him peace, was sitting at the grave. I saw his eyes shedding tears. Then he said: "Is there any man among you who did not commit an act last night?" Surayj said: meaning a sin. Abu Talhah said: "I, O Messenger of Allah." He said: "Then descend." He said: So he descended into her grave.
