Once the Prophet (ﷺ) asked for a tumbler containing water. He washed his hands and face in it and also threw a mouthful of water in it.
Sahih al-Bukhari Book 4, Hadith 62
← Previous Hadith It was the time for prayer, and those whose houses were near got up and went to their people (to perform ablution), and there remained some people (sitting). Then a painted stove pot (Mikhdab) containing water was brought to Allah's Messenger (ﷺ)s The pot was small, not broad enough for one to spread one's hand in; yet all the people performed ablution. (The sub narrator said, "We asked Anas, 'How many persons were you?' Anas replied 'We were eighty or more"). (It was one of the miracles of Allah's Messenger (ﷺ)).

Sahih al-Bukhari Book 4, Hadith 61 Next Hadith → Once Allah's Messenger (ﷺ) came to us and we brought out water for him in a brass pot. He performed ablution thus: He washed his face thrice, and his forearms to the elbows twice, then passed his wet hands lightly over the head from front to rear and brought them to front again and washed his feet (up to the ankles).
