Sunan an-Nasai
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَعَلِيُّ بْنُ حُجْرٍ، - وَاللَّفْظُ لَهُ - أَنْبَأَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ أُمِّهِ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ كَانَ رَأْسُ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي حِجْرِ إِحْدَانَا وَهِيَ حَائِضٌ وَهُوَ يَتْلُو الْقُرْآنَ .
It was narrated that 'Aishah said: "The head of the Messenger of Allah (ﷺ) would rest in the lap of one of us when she was menstruating, and he would recite Qur'an."
