Abdullah bin Muhammad bin Aqil said: A group of us went to Sayyidah al-Rubayyi' bint Mu'awwidh bin Afra (may Allah be pleased with her) and asked her about the ablution (wudu) of the Messenger of Allah (peace and blessings be upon him). She said: "Yes, the Messenger of Allah (peace and blessings be upon him) used to perform ablution from a vessel like this" — and she was pointing with her hand to a small vessel which, as I think, held one and a third mudd of water by the old measure — "He (peace and blessings be upon him) rinsed his mouth, sniffed water into his nose, washed his face and hands three times, then wiped the front and back of his head, wiped his ears together with the back of his head, and washed his feet."
