مسند أحمد

It was narrated that Abu Hayyah al-Wadi`i said: I saw ‘Ali (رضي الله عنه) urinate in ar-Rahbah, then he called for water and did wudoo’. He washed his hands three times, rinsed his mouth and nose three times, washed his face three times, washed his forearms three times each, wiped his head and washed his feet three times each. Then he said: I saw the Messenger of Allah (ﷺ) do as you have seen me do.
