It was narrated that 'Aishah said: I used to eat the meat from a bone when I was menstruating, then the Messenger of Allah would take it and put his mouth where my mouth had been. And I would drink from a vessel, and the Messenger of Allah would take it and put his mouth where my mouth had been, and I was menstruating.
It was narrated from Anas that: The Jews would not sit with a menstruating woman in a house, nor eat with her, nor drink with her. That was mentioned to the Messenger of Allah, then Allah revealed the words: They ask you concerning menstruation. Say: that is a harmful thing, therefore keep away from women during menses. The Messenger of Allah said: Do everything except sexual intercourse.
