[Machine] In the name of Allah, the Most Gracious, the Most Merciful. The verse "So whoever among you is ill or has harm (in his hair) from the head must ransom (the fasting) by feeding the poor or offering a sacrifice or giving charity" was revealed. I asked, "What happened to you?" He said, "We went out with the Messenger of Allah ﷺ in a state of ihram, and lice infested my head, beard, and mustache, until it reached my eyebrows. This was mentioned to the Prophet ﷺ, so he said, 'I did not think that it would be difficult for you, so call the barber.' He called the barber and had his head shaved. Then he asked, 'Do you have anything to offer as ransom?' I said, 'No.' He said, 'Then fast for three days or feed six poor people, giving each poor person half a sa' of food.' This verse was revealed specifically for me, but it is general for all people."  

فِيَّ نَزَلَتْ هَذِهِ الْآيَةُ {فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ} قُلْتُ كَيْفَ كَانَ شَأْنُكَ؟ قَالَ خَرَجْنَا مَعَ رَسُولِ اللهِ ﷺ وَنَحْنُ مُحْرِمُونَ فَوَقَعَ الْقَمْلُ فِي رَأْسِي وَلِحْيَتِي وَشَارِبِي حَتَّى وَقَعَ فِي حَاجِبَيَّ فَذُكِرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ «مَا كُنْتُ أَرَى بَلَغَ بِكَ هَذَا ادْعُ الْحَلَّاقَ» فَدَعَا الْحَلَّاقَ فَحَلَقَ رَأْسَهُ فَقَالَ «هَلْ تَجِدُ نَسِيكَةً؟» قُلْتُ لَا قَالَ «فَصُمْ ثَلَاثَةَ أَيَّامٍ أَوْ أَطْعِمْ سِتَّةَ مَسَاكِينٍ بَيْنَ كُلِّ مِسْكِينَيْنِ صَاعٌ» فَنَزَلَتْ فِيَّ خَاصَّةً وَلِلنَّاسِ عَامَّةً  

I cannot afford it. He then commanded him to observe fasts for three days or feed six needy persons, one sa' for every two needy persons. And Allah the Exalted and Majestic revealed this (verse) particular with regard to him:" So whosoever among you is sick and has an ailment of the head.." ; then (its application) became general for the Muslims. (Using translation from Muslim 1201h)  

أَنَّهُ خَرَجَ مَعَ النَّبِيِّ ﷺ مُحْرِمًا فَقَمِلَ رَأْسُهُ وَلِحْيَتُهُ فَبَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَأَرْسَلَ إِلَيْهِ فَدَعَا الْحَلَّاقَ فَحَلَقَ رَأْسَهُ ثُمَّ قَالَ «هَلْ عِنْدَكَ نُسُكٌ؟» قَالَ مَا أَقْدِرُ عَلَيْهِ فَأَمَرَهُ أَنْ يَصُومَ ثَلَاثَةَ أَيَّامٍ أَوْ يُطْعِمَ سِتَّةَ مَسَاكِينٍ لِكُلِّ مِسْكِينٍ صَاعٌ فَأَنْزَلَ اللهُ ﷻ فِيهِ خَاصَّةً {فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ} ثُمَّ كَانَتْ لِلْمُسْلِمِينَ عَامَّةً
