Musannaf Ibn Abi Shayba 27:27

Hatim ibn Isma'il narrated to us, from Anas ibn Abi Yahya, from his father, from Abu Sa'id, who said: The Messenger of Allah (may Allah bless him and grant him peace) went out while we were in the mosque, and he had his head bound with a piece of cloth during the illness in which he died. He inclined toward the pulpit, and we followed him. He said: "By the One in Whose hand is my soul, I am standing at the Basin (al-Hawd) at this very moment."
