(3) باب جَوَازِ غَسلِ الْحَائِضِ رَأْسَ زَوْجِهَا وَتَرْجِيلِهِ وَطَهَارَةِ سُؤْرِهَا وَالاِتِّكَاءِ فِي حِجْرِهَا وَقِرَاءَةِ الْقُرْآنِ فِيهِ
'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.
