Musnad Ahmad 1153:1161

'Abd al-Razzaq narrated to us, Ma'mar informed us, from al-Zuhri, from 'Urwah or 'Amrah, from 'Aishah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said during his illness in which he died: "Pour over me from seven water skins whose ties have not been loosened, so that perhaps I may find relief and then give instructions to the people." 'Aishah said: So we seated him in a tub belonging to Hafsah, made of copper, and we poured water over him from them until he began to signal to us that you have done enough. Then he went out.
