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
