Ayesha reported,

I used to gnaw meat from a bone while I was menstruating, then the Messenger of Allah ﷺ would take it and place his mouth where mine had been. And I would drink from a vessel, then the Messenger of Allah ﷺ would take it and place his mouth where mine had been, while I was menstruating.

Ibn Majah 643

حدثنا محمد بن بشار حدثنا محمد بن جعفر حدثنا شعبة عن المقدام بن شريح بن هانئ عن أبيه

عن عائشة قالت

كنت أتعرق العظم وأنا حائض فيأخذه رسول الله ﷺ فيضع فمه حيث كان فمي وأشرب من الإناء فيأخذه رسول الله ﷺ فيضع فمه حيث كان فمي وأنا حائض
