Narrated Ka`b bin 'Ujara:
حَدَّثَنَا قَبِيصَةُ ، حَدَّثَنَا سُفْيَانُ ، عَنِ ابْنِ أَبِي نَجِيحٍ ، وَأَيُّوبَ ، عَنْ مُجَاهِدٍ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى ، عَنْ كَعْبِ بْنِ عُجْرَةَ ـ رضى الله عنه. مَرَّ بِيَ النَّبِيُّ صلى الله عليه وسلم وَأَنَا أُوقِدُ تَحْتَ الْقِدْرِ فَقَالَ " أَيُؤْذِيكَ هَوَامُّ رَأْسِكَ ". قُلْتُ نَعَمْ. فَدَعَا الْحَلاَّقَ فَحَلَقَهُ ثُمَّ أَمَرَنِي بِالْفِدَاءِ.
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."
