البخاري:٣٩٥٤حَدَّثَنِي 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
