I would eat flesh from a bone when I was menstruating, then hand it over to the Prophet ﷺ and he would put his mouth where I had put my mouth: I would drink, then hand it over to him, and he would put his mouth( at the place) where I drank.
كُنْتُ أَتَعَرَّقُ الْعَظْمَ وَأَنَا حَائِضٌ فَأُعْطِيهِ النَّبِيَّ ﷺ فَيَضَعُ فَمَهُ فِي الْمَوْضِعِ الَّذِي فِيهِ وَضَعْتُهُ وَأَشْرَبُ الشَّرَابَ فَأُنَاوِلُهُ فَيَضَعُ فَمَهُ فِي الْمَوْضِعِ الَّذِي كُنْتُ أَشْرَبُ مِنْهُ
"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."
كُنْتُ أَتَعَرَّقُ الْعَظْمَ وَأَنَا حَائِضٌ فَيَأْخُذُهُ رَسُولُ اللَّهِ ﷺ فَيَضَعُ فَمَهُ حَيْثُ كَانَ فَمِي وَأَشْرَبُ مِنَ الإِنَاءِ فَيَأْخُذُهُ رَسُولُ اللَّهِ ﷺ فَيَضَعُ فَمَهُ حَيْثُ كَانَ فَمِي وَأَنَا حَائِضٌ
"I would drink while I was menstruating, then I would hand it to the Prophet ﷺ, and he would put his mouth where mine had been and drink. And I would nibble at the bone on which some bits of meat were left while I was menstruating, then I would give it to the Prophet ﷺ and he would put his mouth where my mouth had been." (Using translation from Nasāʾī 282)
كُنْتُ أَشْرَبُ وَأَنَا حَائِضٌ فَأُنَاوِلُهُ النَّبِيَّ ﷺ فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ فَيَشْرَبُهُ وَأَتَعَرَّقُ الْعَرْقَ وَأَنَا حَائِضٌ فَأُنَاوِلُهُ النَّبِيَّ ﷺ «فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ»
