[Machine] The Prophet ﷺ stopped at Al-Hudaybiyah, and as he did, lice were crawling on his head. He asked, "Do your lice harm you?" I replied, "Yes." He then said, "Shave your head." In the Quran, Allah said, "And whoever among you is ill or has an ailment of the head, then a ransom of fasting [three days], or charity or sacrifice [is required]" (2:196). The Messenger of Allah ﷺ commanded me to observe fasting for three days, or give charity, or make a sacrifice according to my capability.
أَنَّ النَّبِيَّ ﷺ وَقَفَ عَلَيْهِ بِالْحُدَيْبِيَةِ قَالَ وَرَأْسُهُ يَتَهَافَتُ قَمْلًا قَالَ أَيُؤْذِيكَ هَوَامُّكَ ؟ قَالَقُلْتُ نَعَمْ قَالَ فَاحْلِقْ رَأْسَكَ قَالَ فِيَّ نَزَلَتْ {فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ} [البقرة 196] قَالَ فَأَمَرَنِي رَسُولُ اللهِ ﷺ فَقَالَ صُمْ ثَلَاثَةَ أَيَّامٍ أَوْ تَصَدَّقْ بِفِرْقٍ بَيْنَ سِتَّةٍ أَوْ بِنُسُكٍ مَا تَيَسَّرَ
