صحيح البخاري#4190Sahihحَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ أَبِي لَيْلَى، عَنْ كَعْبِ بْنِ عُجْرَةَ ـ رضى الله عنه ـ قَالَ أَتَى عَلَىَّ النَّبِيُّ صلى الله عليه وسلم زَمَنَ الْحُدَيْبِيَةِ، وَالْقَمْلُ يَتَنَاثَرُ عَلَى وَجْهِي فَقَالَ {أَيُؤْذِيكَ هَوَامُّ رَأْسِكَ}. قُلْتُ نَعَمْ. قَالَ " فَاحْلِقْ، وَصُمْ ثَلاَثَةَ أَيَّامٍ، أَوْ أَطْعِمْ سِتَّةَ مَسَاكِينَ، أَوِ انْسُكْ نَسِيكَةً ". قَالَ أَيُّوبُ لاَ أَدْرِي بِأَىِّ هَذَا بَدَأَ.
Narrated Ka`b bin Ujra:The Prophet (ﷺ) came to me at the time of Al-Hudaibiya Pledge while lice were falling on my face. He said, "Are the lice of your head troubling you?" I said, "Yes." He said, "Shave your head and fast for three days, or feed six poor persons, or slaughter a sheep as sacrifice." (The sub-narrator, Aiyub said, "I do not know with which of these three options he started)
Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. When they judged only its chain of narrators (“Isnaad”), the label says “Sound chain”. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
