(16) باب قَوْلِ الْمَرِيضِ إِنِّي وَجِعٌ أَوْ وَارَأْسَاهْ، أَوِ اشْتَدَّ بِي الْوَجَعُ
Narrated Ka`b bin 'Ujara:
The Prophet (ﷺ) passed by me while I was kindling a fire under a (cooking) pot. He said, "Do the lice of your head trouble you?" I said, "Yes." So he called a barber to shave my head and ordered me to make expiation for that."
