Narrated Al-Qasim bin Abi Bazza:
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى ، أَخْبَرَنَا هِشَامُ بْنُ يُوسُفَ ، أَنَّ ابْنَ جُرَيْجٍ ، أَخْبَرَهُمْ قَالَ أَخْبَرَنِي الْقَاسِمُ بْنُ أَبِي بَزَّةَ ، أَنَّهُ سَأَلَ سَعِيدَ بْنَ جُبَيْرٍ هَلْ لِمَنْ قَتَلَ مُؤْمِنًا مُتَعَمِّدًا مِنْ تَوْبَةٍ فَقَرَأْتُ عَلَيْهِ {وَلاَ يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ إِلاَّ بِالْحَقِّ} . فَقَالَ سَعِيدٌ قَرَأْتُهَا عَلَى ابْنِ عَبَّاسٍ كَمَا قَرَأْتَهَا عَلَىَّ. فَقَالَ هَذِهِ مَكِّيَّةٌ نَسَخَتْهَا آيَةٌ مَدَنِيَّةٌ، الَّتِي فِي سُورَةِ النِّسَاءِ.
That he asked Sa`id bin Jubair, "Is there any repentance of the one who has murdered a believer intentionally?" Then I recited to him:-- "Nor kill such life as Allah has forbidden except for a just cause." Sa`id said, "I recited this very Verse before Ibn `Abbas as you have recited it before me. Ibn `Abbas said, 'This Verse was revealed in Mecca and it has been abrogated by a Verse in Surat-An-Nisa which was later revealed in Medina."
