Ayesha reported,

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

Nasai 342

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