١۔ كتاب الطهارة
"The Messenger of Allah ﷺ used to lay his head in the lap of one of us while she was menstruating and recite Qur'an, and one of us would take the mat to the Masjid and spread it out while she was menstruating."
كَانَ رَسُولُ اللَّهِ ﷺ يَضَعُ رَأْسَهُ فِي حِجْرِ إِحْدَانَا فَيَتْلُو الْقُرْآنَ وَهِيَ حَائِضٌ وَتَقُومُ إِحْدَانَا بِالْخُمْرَةِ إِلَى الْمَسْجِدِ فَتَبْسُطُهَا وَهِيَ حَائِضٌ
