حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحِ بْنِ هَانِئٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كُنْتُ أَتَعَرَّقُ الْعَظْمَ وَأَنَا حَائِضٌ، فَيَأْخُذُهُ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فَيَضَعُ فَمَهُ حَيْثُ كَانَ فَمِي وَأَشْرَبُ مِنَ الإِنَاءِ فَيَأْخُذُهُ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فَيَضَعُ فَمَهُ حَيْثُ كَانَ فَمِي وَأَنَا حَائِضٌ ‏.‏

It was narrated from Anas that

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."
