Ayesha reported,

I would gnaw on a bone with meat still on it, and the Messenger of Allah ﷺ would place his mouth where I had placed mine, even while I was menstruating. I would also drink from a vessel, and he would place his mouth where I had placed mine, even while I was menstruating.

كنت أتعرق العرق فيضع رسول الله ﷺ فاه حيث وضعت وأنا حائض وكنت أشرب من الإناء فيضع فاه حيث وضعت وأنا حائض
