أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، عَنْ سُفْيَانَ، عَنْ مَنْبُوذٍ، عَنْ أُمِّهِ، أَنَّ مَيْمُونَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَضَعُ رَأْسَهُ فِي حِجْرِ إِحْدَانَا فَيَتْلُو الْقُرْآنَ وَهِيَ حَائِضٌ وَتَقُومُ إِحْدَانَا بِخُمْرَتِهِ إِلَى الْمَسْجِدِ فَتَبْسُطُهَا وَهِيَ حَائِضٌ ‏.‏
