عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يُجَاوِرُ فِي الْمَسْجِدِ فَيُصْغِي إِلَيَّ رَأْسَهُ فَأُرَجِّلُهُ وَأَنَا حَائِضٌ
It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: The Messenger of Allah (peace and blessings be upon him) used to be in the state of i'tikaf in the mosque and would lean his blessed head towards me, so I would comb his (peace and blessings be upon him) hair while I was menstruating.
