Hadith 386
أَخْبَرَنَا نَصْرُ بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا عَبْدُ الأَعْلَى، قَالَ حَدَّثَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، أَنَّهَا كَانَتْ تُرَجِّلُ رَأْسَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهِيَ حَائِضٌ وَهُوَ مُعْتَكِفٌ فَيُنَاوِلُهَا رَأْسَهُ وَهِيَ فِي حُجْرَتِهَا .
It was narrated from 'Aishah that she used to comb the hair of the Messenger of Allah (ﷺ) when she was menstruating and he was performing I'tikaf. He would put his head out to her while she was in her room.
