Arabic hadith text
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، فَقَالَنَزَلَتْ فِي آخِرِ مَا نَزَلَ وَلَمْ يَنْسَخْهَا شَىْءٌ.
Translation
Narrated Sa`id bin Jubair
The people of Kufa differed as regards the killing of a believer so I entered upon Ibn `Abbas (and asked him) about that. Ibn `Abbas said, "The Verse (in Surat-An-Nisa', 4:93) was the last thing revealed in this respect and nothing cancelled its validity."
