مسند أحمد

It was narrated that ‘Abd Khair said: We came to ‘Ali (رضي الله عنه) when he had prayed. He called for a jug, then he rinsed his mouth three times, and rinsed his nose three times. He rinsed his mouth from the hand that held the water. And he washed his face three times, his right arm three times and his left arm three times. Then he said: Whoever would like to know how the Messenger of Allah (ﷺ) did wudoo’, this is it.
