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." Translation Not Available
