عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يُجَاوِرُ فِي الْمَسْجِدِ فَيُصْغِي إِلَيَّ رَأْسَهُ فَأُرَجِّلُهُ وَأَنَا حَائِضٌ
Narrated by Sayyida Aisha (may Allah be pleased with her), she said: When the Messenger of Allah (peace and blessings be upon him) used to observe i'tikaf in the mosque, he would lean his blessed head towards me and I would comb his hair, while I was in the state of menstruation during those days.
