ثنا عَلِيُّ بْنُ عَبْدِ اللَّهِ بْنِ مُبَشِّرٍ ، نا أَحْمَدُ بْنُ سِنَانٍ ، نا يَزِيدُ بْنُ هَارُونَ ، نا دَاوُدُ بْنُ أَبِي هِنْدَ ، عَنْ عَامِرٍ ، عَنْ كَعْبِ بْنِ عُجْرَةَ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَرَّ بِهِ وَلَهُ وَفْرَةٌ ، وَبِأَصْلِ كُلِّ شَعْرَةٍ وَبِأَعْلاهَا قَمْلَةٌ أَوْ صُؤَابٌ ، فَقَالَ لَهُ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " إِنَّ هَذَا الأَذَى أَمَعَكَ نُسُكٌ ؟ " ، قَالَ : لا ، قَالَ : " فَإِنْ شِئْتَ فَصُمْ ثَلاثَةَ أَيَّامٍ ، أَوْ أَطْعِمْ ثَلاثَةَ آصُعٍ مِنْ تَمْرٍ بَيْنَ كُلِّ مِسْكِينٍ صَاعٌ " .
Sayyiduna Ka'b bin 'Ujrah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) passed by him; his hair was long, and there were lice at the roots and on the upper part of his hair. The Noble Prophet (peace and blessings be upon him) said to him: "You are in difficulty. Do you have a sacrificial animal with you?" He replied: "No!" The Prophet said: "Then if you wish, fast for three days, or feed three sa's of dates (to the poor), giving each needy person one sa'."
