Musnad Ahmad 5:434

'Abdullah narrated to us, Abu Bakr ibn Abi Shaybah narrated to me, Sharik narrated to us, from Khalid ibn 'Alqamah, from 'Abd Khayr, from 'Ali, who said: "He performed ablution, so he rinsed his mouth three times, and inhaled water into his nose three times, from a single handful. He washed his face three times, then he inserted his hand into the water vessel and wiped his head, and washed his feet." Then he said: "This is the ablution of your Prophet, may Allah bless him and grant him peace."
