"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  

The Jews would not sit with a menstruating woman in a house, nor eat with her, nor drink with her. That was mentioned to the Messenger of Allah, then Allah revealed the words: "They ask you concerning menstruation. Say: that is a harmful thing, therefore keep away from women during menses." The Messenger of Allah said: "Do everything except sexual intercourse."  

أَنَّ الْيَهُودَ كَانُوا لاَ يَجْلِسُونَ مَعَ الْحَائِضِ فِي بَيْتٍ وَلاَ يَأْكُلُونَ وَلاَ يَشْرَبُونَ قَالَ فَذُكِرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَأَنْزَلَ اللَّهُ {وَيَسْأَلُونَكَ عَنِ الْمَحِيضِ قُلْ هُوَ أَذًى فَاعْتَزِلُوا النِّسَاءَ فِي الْمَحِيضِ} فَقَالَ رَسُولُ اللَّهِ ﷺ اصْنَعُوا كُلَّ شَىْءٍ إِلاَّ الْجِمَاعَ
