'A'isha reported:
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، أَخْبَرَنَا دَاوُدُ بْنُ عَبْدِ الرَّحْمَنِ الْمَكِّيُّ ، عَنْ مَنْصُورٍ ، عَنْ أُمِّهِ ، عَنْ عَائِشَةَ ، أَنَّهَا قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَتَّكِئُ فِي حِجْرِي وَأَنَا حَائِضٌ فَيَقْرَأُ الْقُرْآنَ .
The Messenger of Allah (ﷺ) would recline in my lap when I was menstruating, and recite the Qur'an.
