[Machine] The Prophet ﷺ used to have his head shaved near the mosque, and I would wash his head while I was menstruating. Abu 'Abd al-Rahman said: Hisham ibn 'Urwah narrated this hadith and did not mention that I was menstruating.  

كَانَ رَسُولُ اللهِ ﷺ «يُخْرِجُ إِلَيَّ رَأْسَهُ مِنَ الْمَسْجِدِ وَهُوَ مُجَاوِرٌ فَأَغْسِلُهُ وَأَنَا حَائِضٌ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ رَوَاهُ هِشَامُ بْنُ عُرْوَةَ وَلَمْ يَذْكُرْ وَهُوَ مُجَاوِرٌ  

While in menses, I used to comb the hair of Messenger of Allah ﷺ . (Using translation from Bukhārī 295)  

«كُنْتُ أُرَجِّلُ رَأْسَ رَسُولِ اللهِ ﷺ وَأَنَا حَائِضٌ»
