Sunan Abi Dawud 111

Musaddad narrated to us; Abu Awanah narrated to us, from Khalid ibn Alqamah, from Abd Khayr, who said: Ali (may Allah be pleased with him) came to us after he had prayed and called for water for purification. We said: ‘What will he do with water, since he has already prayed? He must only be teaching us.’ A vessel containing water and a washbasin were brought. He poured from the vessel onto his right hand and washed his hands three times. He rinsed his mouth and cleared his nose three times, rinsing and expelling from the handful with which he took water. He washed his face three times, then his right hand three times and his left three times. Then he put his hand in the vessel, took water, and wiped his head once. He washed his right foot three times and his left three times, then said: ‘Whoever wishes to know how the Messenger of Allah (peace and blessings be upon him) performed ablution, this is it.’
