صَحِيحُ مُسْلِمٍ
Sahih Muslim 297 d
The Book of Menstruation
It is permissible for a menstruating woman to wash her husband’s head, and comb his hair; her leftovers are pure (tahir); and regarding reclining in her lap and reciting Qur’an
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو خَيْثَمَةَ، عَنْ هِشَامٍ، أَخْبَرَنَا عُرْوَةُ، عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُدْنِي إِلَىَّ رَأْسَهُ وَأَنَا فِي حُجْرَتِي فَأُرَجِّلُ رَأْسَهُ وَأَنَا حَائِضٌ .
'Urwa reported it from 'A'isha that she observed: The Messenger of Allah (ﷺ) inclined his head towards me (from the mosque) while I was in my apartment and I combed it in a state of menstruation.
