It was narrated from Rib’i bin Hirash that `Ali bin Abi Talib (رضي الله عنه) stood up to deliver a speech in ar-Rahbah. He praised and glorified Allah, then he said what Allah willed that he should say, then he called for a vessel of water. He rinsed his mouth, washed himself, and drank what was left over whilst standing. Then he said: I heard that one of you dislikes drinking whilst standing. This is the wudoo’ of one who has not broken his wudoo’. And I saw the Messenger of Allah (ﷺ) do this.
