Arabic

حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، عَنِ الْمُغِيرَةِ بْنِ النُّعْمَانِ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ اخْتَلَفَ أَهْلُ الْكُوفَةِ فِي قَتْلِ الْمُؤْمِنِ، فَرَحَلْتُ فِيهِ إِلَى ابْنِ عَبَّاسٍ، فَقَالَ نَزَلَتْ فِي آخِرِ مَا نَزَلَ وَلَمْ يَنْسَخْهَا شَىْءٌ‏.‏
