عَبْدُ الرَّحْمَنِ بْنُ أَبِي لَيْلَى ، حَدَّثَنِي
كَعْبُ بْنُ عُجْرَةَ رَضِيَ اللَّهُ عَنْهُ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَقَفَ عَلَيْهِ ، وَرَأْسُهُ يَتَهَافَتُ قَمْلًا ، فَقَالَ : " أَيُؤْذِيكَ هَوَامُّكَ ؟ ، قُلْتُ : نَعَمْ ، قَالَ : فَاحْلِقْ رَأْسَكَ ، قَالَ : فَفِيَّ نَزَلَتْ هَذِهِ الْآيَةُ فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ سورة البقرة آية 196 ، فَقَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : صُمْ ثَلَاثَةَ أَيَّامٍ أَوْ تَصَدَّقْ بِفَرَقٍ بَيْنَ سِتَّةِ مَسَاكِينَ أَوِ انْسُكْ مَا تَيَسَّرَ " .
Ka'b bin 'Ujra (RA) reported that the Messenger of Allah (ﷺ) 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.
