Sahih Muslim | Book 3 | Hadith Number 630

Narrated by 'Aisha
'Aisha reported: I and the Messenger of Allah (may peace be upon him) took a bath from one vessel which was placed between me and him and he would get ahead of me, so that I would say: Spare (some water for) me, spare (some water for) me; and she said that they had had sexual intercourse.
