I came to `Ali (رضي الله عنه) and he had prayed. He called for water for wudoo’. We said: What is he going to do with water when he has just prayed? He can only want to teach us something. A large vessel and a small vessel were brought to him. He lifted the small vessel and poured water over his hand and washed it three times. Then he dipped his hand in the vessel and rinsed his mouth and nose three times, and he did that from the same handful of water that he had taken. Then he washed his face three times, his right arm three times and his left arm three times. Then he put his hand in the water and wiped his head once. Then he washed his right foot three times and his left foot three times. Then he said: Whoever would like to learn the wudoo’ of the Messenger of Allah (ﷺ), this is it.
