حَدَّثَنِي أَبُو عَبْدِ اللَّهِ بْنُ الْمُهْتَدِي بِاللَّهِ ، نا طَاهِرُ بْنُ عِيسَى بْنِ إِسْحَاقَ التَّمِيمِيُّ ، نا زُهَيْرُ بْنُ عَبَّادٍ ، نا مُصْعَبُ بْنُ مَاهَانَ ، عَنْ سُفْيَانَ الثَّوْرِيِّ ، عَنِ ابْنِ أَبِي نَجِيحٍ ، وَأَيُّوبَ ، وَسَيْفٍ ، عَنْ مُجَاهِدٍ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى ، عَنْ كَعْبِ بْنِ عُجْرَةَ ، قَالَ : مَرَّ بِهِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يُوقِدُ تَحْتَ قِدْرٍ لَهُ وَهُوَ بِالْحُدَيْبِيَةِ ، فَقَالَ لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " أَيُؤْذِيكَ هَوَامُّ رَأْسِكَ ؟ " ، قَالَ : نَعَمْ ، قَالَ : " احْلِقْ " ، فَأُنْزِلَتْ هَذِهِ الآيَةُ فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ سورة البقرة آية 196 . فَالصِّيَامُ ثَلاثَةُ أَيَّامٍ ، وَالصَّدَقَةُ فَرَقٌ بَيْنَ سِتَّةِ مَسَاكِينَ ، وَالنُّسُكُ شَاةٌ .
Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings of Allah be upon him) passed by him while he was kindling a fire under his cooking pot. This was during the incident of Hudaybiyyah. The Noble Prophet (peace and blessings of Allah be upon him) asked him: "Are lice troubling you?" The Noble Prophet (peace and blessings of Allah be upon him) said: "Shave your head." (The narrator states) Then this verse was revealed: "So whoever among you is ill or has an ailment of the head, then (he should offer) a ransom of fasting or charity or sacrifice." The command for fasting is to fast for three days. By charity, it means to give one faraq to six needy people, and by sacrifice, it means to offer a goat.
