Sahih al-Bukhari, Hadith 2028 ⓘ
Narrated `Aisha: The Prophet used to (put) bend his head (out) to me while he was in I`tikaf in the mosque during my monthly periods and I would comb and oil his hair.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، عَنْ هِشَامٍ، قَالَ أَخْبَرَنِي أَبِي، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ النَّبِيُّ صلى الله عليه وسلم يُصْغِي إِلَىَّ رَأْسَهُ وَهْوَ مُجَاوِرٌ فِي الْمَسْجِدِ، فَأُرَجِّلُهُ وَأَنَا حَائِضٌ.
