from Ka'b bin 'Ujrah who said: "The Messenger of Allah ﷺ came to me while I was lighting a fire under a pot, and lice were falling on my face, or on my eye-brows. He said: 'Are your lice bothering you?'" [He said:] "I said: 'Yes.' He said: 'Then shave your head and offer a sacrifice, or fast three days, or feed six needy people.'" Ayyub said: "I do not know which of them he started with." (Using translation from Tirmidhī 2974)
أَتَى عَلَيَّ رَسُولُ اللهِ ﷺ وَأَنَا أُوقِدُ تَحْتَ قِدْرٍ وَالْقَمْلُ يَتَنَاثَرُ عَلَى وَجْهِي أَوْ قَالَ حَاجِبَيَّ فَقَالَ أَيُؤْذِيكَ هَوَامُّ رَأْسِكَ؟ قَالَ قُلْتُ نَعَمْ قَالَ فَاحْلِقْهُ وَصُمْ ثَلَاثَةَ أَيَّامٍ أَوْ أَطْعِمْ سِتَّةَ مَسَاكِينَ أَوْ انْسُكْ نَسِيكَةً قَالَ أَيُّوبُ لَا أَدْرِي بِأَيَّتِهِنَّ بَدَأَ
