6) بَابُ قَوْلِ اللَّهِ تَعَالَى: {أَوْ صَدَقَةٍ} وَهْيَ إِطْعَامُ سِتَّةِ مَسَاكِينَ

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سَيْفٌ، قَالَ حَدَّثَنِي مُجَاهِدٌ، قَالَ سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ أَبِي لَيْلَى، أَنَّ كَعْبَ بْنَ عُجْرَةَ، حَدَّثَهُ قَالَ وَقَفَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم بِالْحُدَيْبِيَةِ، وَرَأْسِي يَتَهَافَتُ قَمْلاً فَقَالَ ‏"‏ يُؤْذِيكَ هَوَامُّكَ ‏"‏‏.‏ قُلْتُ نَعَمْ‏.‏ قَالَ ‏"‏ فَاحْلِقْ رَأْسَكَ ـ أَوْ قَالَ ـ احْلِقْ ‏"‏‏.‏ قَالَ فِيَّ نَزَلَتْ هَذِهِ الآيَةُ ‏{‏فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِنْ رَأْسِهِ‏}‏ إِلَى آخِرِهَا‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ صُمْ ثَلاَثَةَ أَيَّامٍ، أَوْ تَصَدَّقْ بِفَرَقٍ بَيْنَ سِتَّةٍ، أَوِ انْسُكْ بِمَا تَيَسَّرَ ‏"‏‏.‏
