Ka’ab bin ‘Ujrah said that the Apostle of Allaah ﷺ came upon him (during their stay) at Al Hudaibiyyah. He asked do the insects of your head (lice) annoy you? He said Yes. The Prophet ﷺ said Shave your head, then sacrifice a sheep as offering or fast three days or give three sa’s of dates to six poor people.  

أَنَّ رَسُولَ اللَّهِ ﷺ مَرَّ بِهِ زَمَنَ الْحُدَيْبِيَةِ فَقَالَ قَدْ آذَاكَ هَوَامُّ رَأْسِكَ قَالَ نَعَمْ فَقَالَ النَّبِيُّ ﷺ احْلِقْ ثُمَّ اذْبَحْ شَاةً نُسُكًا أَوْ صُمْ ثَلاَثَةَ أَيَّامٍ أَوْ أَطْعِمْ ثَلاَثَةَ آصُعٍ مِنْ تَمْرٍ عَلَى سِتَّةِ مَسَاكِينَ  

Ka’ab bin ‘Ujrah said that the Apostle of Allaah ﷺ said to him, If you like sacrifice an animal or if you like fast three days or if you like give three sa’s of dates to six poor people.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَهُ إِنْ شِئْتَ فَانْسُكْ نَسِيكَةً وَإِنْ شِئْتَ فَصُمْ ثَلاَثَةَ أَيَّامٍ وَإِنْ شِئْتَ فَأَطْعِمْ ثَلاَثَةَ آصُعٍ مِنْ تَمْرٍ لِسِتَّةِ مَسَاكِينَ  

The Messenger of Allah ﷺ came upon him (during their stay) at al-Hudaybiyyah. He then narrated the rest of the tradition. This version adds: "He asked: Do you have a sacrificial animal? He replied: No. He then said: Fast three days or give three sa's of dates to six poor people, giving one sa' to every two persons."  

أَنَّ رَسُولَ اللَّهِ ﷺ مَرَّ بِهِ زَمَنَ الْحُدَيْبِيَةِ فَذَكَرَ الْقِصَّةَ فَقَالَ أَمَعَكَ دَمٌ قَالَ لاَ قَالَ فَصُمْ ثَلاَثَةَ أَيَّامٍ أَوْ تَصَدَّقْ بِثَلاَثَةِ آصُعٍ مِنْ تَمْرٍ عَلَى سِتَّةِ مَسَاكِينَ بَيْنَ كُلِّ مِسْكِينَيْنِ صَاعٌ  

A man from the Ansar said on the authority of Ka'b ibn Ujrah that he was feeling pain in his head (due to lice); so he shaved his head. The Prophet ﷺ ordered him to sacrifice a cow as offering.  

أَخْبَرَهُ عَنْ كَعْبِ بْنِ عُجْرَةَ وَكَانَ قَدْ أَصَابَهُ فِي رَأْسِهِ أَذًى فَحَلَقَ فَأَمَرَهُ النَّبِيُّ ﷺ أَنْ يُهْدِيَ هَدْيًا بَقَرَةً  

Ka’b bin ‘Ujrah said I had lice in my head when I accompanied the Apostle of Allaah ﷺ in the year of Al Hudaibiyyah so much so that I feared about my eyesight. So Allaah, the exalted revealed these verses about me. “And whoever among you is sick or hath an aliment of the head.” The Apostle of Allaah ﷺ called me and said “Shave your head and fast three days or give a faraq of raisins to six poor men or sacrifice a goat. So, I shaved my head and sacrificed.  

أَصَابَنِي هَوَامُّ فِي رَأْسِي وَأَنَا مَعَ رَسُولِ اللَّهِ ﷺ عَامَ الْحُدَيْبِيَةِ حَتَّى تَخَوَّفْتُ عَلَى بَصَرِي فَأَنْزَلَ اللَّهُ سُبْحَانَهُ وَتَعَالَى { فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ } الآيَةَ فَدَعَانِي رَسُولُ اللَّهِ ﷺ فَقَالَ لِي احْلِقْ رَأْسَكَ وَصُمْ ثَلاَثَةَ أَيَّامٍ أَوْ أَطْعِمْ سِتَّةَ مَسَاكِينَ فَرَقًا مِنْ زَبِيبٍ أَوِ انْسُكْ شَاةً فَحَلَقْتُ رَأْسِي ثُمَّ نَسَكْتُ  

"Whichever of these you do, it will suffice."  

عَنْ كَعْبِ بْنِ عُجْرَةَ فِي هَذِهِ الْقِصَّةِ زَادَ أَىَّ ذَلِكَ فَعَلْتَ أَجْزَأَ عَنْكَ
