It is permissible for a Muhrim to shave his head if there is a problem, but it is obligatory to offer a Fidyah for shaving it, and Clarifying what the Fidyah is

Ka'b b. 'Ujra (Allah be pleased with him) reported: The Messenger of Allah ﷺ came to me on the occasion of Hudaibiya and I was kindling fire under my cooking pot and lice were creeping on my face. Thereupon he (the Holy Prophet) said: Do the vermins harm your head? I said: Yes. He said: Get your head shaved and (in lieu of it) observe fasts for three days or feed six needy persons, or offer sacrifice (of an animal). Ayyub said: I do not know with what (type of expiation) did he commence (the statement).

وَحَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ عُمَرَ الْقَوَارِيرِيُّ، حَدَّثَنَا حَمَّادٌ، - يَعْنِي ابْنَ زَيْدٍ - عَنْ أَيُّوبَ، ح وَحَدَّثَنِي أَبُو الرَّبِيعِ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا أَيُّوبُ، قَالَ سَمِعْتُ مُجَاهِدًا، يُحَدِّثُ عَنْ عَبْدِ الرَّحْمَنِ، بْنِ أَبِي لَيْلَى عَنْ كَعْبِ بْنِ عُجْرَةَ، - رضى الله عنه - قَالَ أَتَى عَلَىَّ رَسُولُ اللَّهِ ﷺ زَمَنَ الْحُدَيْبِيَةِ وَأَنَا أُوقِدُ تَحْتَ - قَالَ الْقْوَارِيرِيُّ قِدْرٍ لِي . وَقَالَ أَبُو الرَّبِيعِ بُرْمَةٍ لِي - وَالْقَمْلُ يَتَنَاثَرُ عَلَى وَجْهِي فَقَالَ " أَيُؤْذِيكَ هَوَامُّ رَأْسِكَ " . قَالَ قُلْتُ نَعَمْ . قَالَ " فَاحْلِقْ وَصُمْ ثَلاَثَةَ أَيَّامٍ أَوْ أَطْعِمْ سِتَّةَ مَسَاكِينَ أَوِ انْسُكْ نَسِيكَةً " . قَالَ أَيُّوبُ فَلاَ أَدْرِي بِأَىِّ ذَلِكَ بَدَأَ .

This hadith is narrated on the authority of Ayyub.

حَدَّثَنِي عَلِيُّ بْنُ حُجْرٍ السَّعْدِيُّ، وَزُهَيْرُ بْنُ حَرْبٍ، وَيَعْقُوبُ بْنُ إِبْرَاهِيمَ، جَمِيعًا عَنِ ابْنِ عُلَيَّةَ، عَنْ أَيُّوبَ، فِي هَذَا الإِسْنَادِ . بِمِثْلِهِ .

Kalb b. Ujra (Allah be pleased with him) reported: It was I for whom this verse was revealed (to the Holy Prophet):" Whoever among you is sick or has an ail- ment of the head, he (may effect) a compensation by lasting or alms or a sacrifice" He said: I came to him (the Holy Prophet) and he said: Come Dear. So Iwent near. He (again) said: Come near. So I went near. Thereupon the Messenger of Allah ﷺ said: Do the vermins trouble you? Ibn Aun (one of the narrators) said: I think he (Ka'b b. Ujra) replied in the affirmative. He (the Holy Prophet) then commanded to do compensation by fasting or by giving @adaqa (feed- ing six needy persons) or by sacrifice (of a animal) that is available.

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنِ ابْنِ عَوْنٍ، عَنْ مُجَاهِدٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنْ كَعْبِ بْنِ عُجْرَةَ، - رضى الله عنه - قَالَ فِيَّ أُنْزِلَتْ هَذِهِ الآيَةُ { فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ} قَالَ فَأَتَيْتُهُ فَقَالَ " ادْنُهْ " . فَدَنَوْتُ فَقَالَ " ادْنُهْ " . فَدَنَوْتُ . فَقَالَ ﷺ " أَيُؤْذِيكَ هَوَامُّكَ " . قَالَ ابْنُ عَوْنٍ وَأَظُنُّهُ قَالَ نَعَمْ . قَالَ فَأَمَرَنِي بِفِدْيَةٍ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ مَا تَيَسَّرَ .

Ka'b b. 'Ujra (Allah be pleased with him) reported that the Messenger of Allah (may peace be, upon him) stood near him and lice were falling from his head. Thereupon he (the Holy Prophet) said: Do these vermins trouble you? I said: Yes. Thereupon he said: Then shave your head;
and it was in connection with me that this verse was revealed:" Whoever among you is sick or has an ailment of the head, he (may effect) a compensation by fasting or alms or a sacrifice". He (the Holy Prophet, therefore) said to me: Observe fast for three days or give a quantity of alms enough to feed six needy persons or offer sacrifice (of an animal) that is available.

وَحَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا سَيْفٌ، قَالَ سَمِعْتُ مُجَاهِدًا، يَقُولُ حَدَّثَنِي عَبْدُ، الرَّحْمَنِ بْنُ أَبِي لَيْلَى حَدَّثَنِي كَعْبُ بْنُ عُجْرَةَ، - رضى الله عنه - أَنَّ رَسُولَ اللَّهِ ﷺ وَقَفَ عَلَيْهِ وَرَأْسُهُ يَتَهَافَتُ قَمْلاً فَقَالَ " أَيُؤْذِيكَ هَوَامُّكَ " . قُلْتُ نَعَمْ . قَالَ " فَاحْلِقْ رَأْسَكَ " . قَالَ فَفِيَّ نَزَلَتْ هَذِهِ الآيَةُ { فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ} فَقَالَ لِي رَسُولُ اللَّهِ ﷺ " صُمْ ثَلاَثَةَ أَيَّامٍ أَوْ تَصَدَّقْ بِفَرَقٍ بَيْنَ سِتَّةِ مَسَاكِينَ أَوِ انْسُكْ مَا تَيَسَّرَ " .

Ka'b b. 'Ujra (Allah be pleased with him) reported that the Apostle of Allah ﷺ happened to pass by him at Hudaibiya before entering Mecca in a state of Ibrim and he (Ka'b) was kindling fire under the cooking pot and virmins were creeping on his (Kalb's) face. Thereupon (the Holy Prophet) said: Dothese vermins trouble you? He (Ka'b) said: Yes. The Messenger of Allah ﷺ said: Shave your head and give some quantity of food enough to feed six needy persons (faraq is equal to three sa's), or observe fast for three days or offer sacri- fice of a sacrificial animal. Ibn Najih (one of the narrators) said:" Or sacrifice a goat."

وَحَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ أَبِي نَجِيحٍ، وَأَيُّوبَ، وَحُمَيْدٍ، وَعَبْدِ، الْكَرِيمِ عَنْ مُجَاهِدٍ، عَنِ ابْنِ أَبِي لَيْلَى، عَنْ كَعْبِ بْنِ عُجْرَةَ، - رضى الله عنه - أَنَّ النَّبِيَّ ﷺ مَرَّ بِهِ وَهُوَ بِالْحُدَيْبِيَةِ قَبْلَ أَنْ يَدْخُلَ مَكَّةَ وَهُوَ مُحْرِمٌ وَهُوَ يُوقِدُ تَحْتَ قِدْرٍ وَالْقَمْلُ يَتَهَافَتُ عَلَى وَجْهِهِ فَقَالَ " أَيُؤْذِيكَ هَوَامُّكَ هَذِهِ " . قَالَ نَعَمْ . قَالَ " فَاحْلِقْ رَأْسَكَ وَأَطْعِمْ فَرَقًا بَيْنَ سِتَّةِ مَسَاكِينَ - وَالْفَرَقُ ثَلاَثَةُ آصُعٍ - أَوْ صُمْ ثَلاَثَةَ أَيَّامٍ أَوِ انْسُكْ نَسِيكَةً " . قَالَ ابْنُ أَبِي نَجِيحٍ " أَوِ اذْبَحْ شَاةً " .

Ka'b b. Ujra (Allah be pleased with him) reported that the Messenger of Allah ﷺ happened to pass by him during the period of Hudaibiya. Thereupon he (the Holy Prophet) said to him (Ka'b b. Ujra): Do these vermins trouble your head? He said: Yes. Thereupon he (the Holy Prophet) said: Shave your head. Then sacrifice a goat or observe fasts for three days or give three sits of dates to feed six needy persons.

وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ، عَنْ خَالِدٍ، عَنْ أَبِي قِلاَبَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنْ كَعْبِ بْنِ عُجْرَةَ، رضى الله عنه أَنَّ رَسُولَ اللَّهِ ﷺ مَرَّ بِهِ زَمَنَ الْحُدَيْبِيَةِ فَقَالَ لَهُ " آذَاكَ هَوَامُّ رَأْسِكَ " . قَالَ نَعَمْ . فَقَالَ لَهُ النَّبِيُّ ﷺ " احْلِقْ رَأْسَكَ ثُمَّ اذْبَحْ شَاةً نُسُكًا أَوْ صُمْ ثَلاَثَةَ أَيَّامٍ أَوْ أَطْعِمْ ثَلاَثَةَ آصُعٍ مِنْ تَمْرٍ عَلَى سِتَّةِ مَسَاكِينَ " .

Abdullah b. Ma'qil said: I sat with Ka'b (Allah be pleased with him) and he was in the mosque. I asked him about this verse:" Compensation in (the form of) fasting, or Sadaqa or sacrifice." Ka'b (Allah be pleased with him) said: It was reveal- ed In my case. There was some trouble in my head. I was taken to the Messenger of Allah ﷺ and lice were creeping upon my face. Thereupon he said: I did not think that your trouble had become so unbearable as I see. Would you be able to afford (the sacrificing) of a goat? I (Ka'b) said: Then this verse was revealed:" Com- pensation (in the form of) fasting or alms or a sacrifice." He (the Holy Prophet) said: (It Implies) fasting for three days, or feeding six needy perscins, half sa' of food for every needy person. This verse was revealed particularly for me and (now) Its applica- tion is general for all of you.

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الأَصْبَهَانِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ مَعْقِلٍ، قَالَ قَعَدْتُ إِلَى كَعْبٍ - رضى الله عنه - وَهُوَ فِي الْمَسْجِدِ فَسَأَلْتُهُ عَنْ هَذِهِ الآيَةِ { فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ} فَقَالَ كَعْبٌ رضى الله عنه نَزَلَتْ فِيَّ كَانَ بِي أَذًى مِنْ رَأْسِي فَحُمِلْتُ إِلَى رَسُولِ اللَّهِ ﷺ وَالْقَمْلُ يَتَنَاثَرُ عَلَى وَجْهِي فَقَالَ " مَا كُنْتُ أُرَى أَنَّ الْجَهْدَ بَلَغَ مِنْكَ مَا أَرَى أَتَجِدُ شَاةً " . فَقُلْتُ لاَ فَنَزَلَتْ هَذِهِ الآيَةُ { فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ} قَالَ صَوْمُ ثَلاَثَةِ أَيَّامٍ أَوْ إِطْعَامُ سِتَّةِ مَسَاكِينَ نِصْفَ صَاعٍ طَعَامًا لِكُلِّ مِسْكِينٍ - قَالَ - فَنَزَلَتْ فِيَّ خَاصَّةً وَهْىَ لَكُمْ عَامَّةً .
