حَدَّثَنِي إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، أَنَّ ابْنَ جُرَيْجٍ، أَخْبَرَهُمْ قَالَ أَخْبَرَنِي عَبْدُ الْكَرِيمِ، أَنَّهُ سَمِعَ مِقْسَمًا، مَوْلَى عَبْدِ اللَّهِ بْنِ الْحَارِثِ يُحَدِّثُ عَنِ ابْنِ عَبَّاسٍ، أَنَّهُ سَمِعَهُ يَقُولُ {لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ} عَنْ بَدْرٍ، وَالْخَارِجُونَ، إِلَى بَدْرٍ.
