“The Messenger of Allah ﷺ used to bring his head towards me when he was next door (observing I’tikaf), and I would wash it and comb his hair, when I was in my apartment and I was menstruating, and he was in the mosque.”  

كَانَ رَسُولُ اللَّهِ ﷺ يُدْنِي إِلَىَّ رَأْسَهُ وَهُوَ مُجَاوِرٌ فَأَغْسِلُهُ وَأُرَجِّلُهُ وَأَنَا فِي حُجْرَتِي وَأَنَا حَائِضٌ وَهُوَ فِي الْمَسْجِدِ
