عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: إِنْ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَيُؤْتَى بِالْإِنَاءِ فَأَشْرَبُ مِنْهُ وَأَنَا حَائِضٌ ثُمَّ يَأْخُذُ فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيِّ، وَإِنْ كُنْتُ لَآخُذُ الْعَرْقَ فَآكُلُ مِنْهُ ثُمَّ يَأْخُذُهُ فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيِّ
It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: A vessel would be brought to the Messenger of Allah (peace and blessings be upon him), I would drink from it first while I was menstruating, then the Prophet (peace and blessings be upon him) would take the vessel and place his mouth where my mouth had been. And I would take a bone with meat on it and eat from it by gnawing the meat off, then the Prophet (peace and blessings be upon him) would take it and place his mouth where my mouth had been.
