An-Nazzal bin Sabrah said: "I saw 'Ali (may Allah be please with him) praying Zuhr, then he sat to tend to the people's needs, and when the time for 'Asr came, a vessel of water was brought to him. He took a handful of it and wiped his face, forearms, head and feet with it, then he took what was left and drank standing up. He said: “People dislike this, but I saw the Messenger of Allah (ﷺ) doing it. This is the Wudu' of one who has not committed Hadath”"
