أَخْبَرَنَا نَصْرُ بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا مُعْتَمِرٌ، عَنْ أَبِيهِ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم ثُمَّ ذَكَرَ كَلِمَةً مَعْنَاهَا قَالَ " ائْتُونِي بِالْكَتِفِ وَاللَّوْحِ " . فَكَتَبَ { لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ } وَعَمْرُو بْنُ أُمِّ مَكْتُومٍ خَلْفَهُ فَقَالَ هَلْ لِي رُخْصَةٌ فَنَزَلَتْ { غَيْرُ أُولِي الضَّرَرِ } .
