`Abdul-Malik bin Sal` said: ‘Abd Khair used to lead us in Fajr prayer, and he said: One day we Prayed Fajr behind `Ali (رضي الله عنه) and when he said the salam he got up and we got up with him. Then he walked until he reached ar-Rahbah where he sat down and leaned his back against the wall. Then he raised his head and said: O Qanbar, bring me the scoop and the big vessel. Then he said to him: Pour (the water). So he poured water for him. He washed his hands three times, then he put his right hand in the vessel and rinsed his mouth and nose three times. Then he put his hand in the vessel and washed his face three times, Then he put his right hand in the vessel and washed his right arm three times, then he washed his left arm three times, And he said: This is the wudoo’ of the Messenger of Allah (ﷺ).
