Sahih al-Bukhari, Volume 6, Book 60, Hadith 114 (USC-MSA) ⓘ

Narrated Sa`id bin Jubair: The people of Kufa disagreed (disputed) about the above Verse. So I went to Ibn `Abbas and asked him about it. He said, "This Verse:-- "And whoever kills a believer intentionally, his recompense is Hell." was revealed last of all (concerning premeditated murder) and nothing abrogated it."

حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا مُغِيرَةُ بْنُ النُّعْمَانِ، قَالَ سَمِعْتُ سَعِيدَ بْنَ جُبَيْرٍ، قَالَ ‏{‏آيَةٌ‏}‏ اخْتَلَفَ فِيهَا أَهْلُ الْكُوفَةِ، فَرَحَلْتُ فِيهَا إِلَى ابْنِ عَبَّاسٍ فَسَأَلْتُهُ عَنْهَا فَقَالَ نَزَلَتْ هَذِهِ الآيَةُ ‏{‏وَمَنْ يَقْتُلْ مُؤْمِنًا مُتَعَمِّدًا فَجَزَاؤُهُ جَهَنَّمُ‏}‏ هِيَ آخِرُ مَا نَزَلَ وَمَا نَسَخَهَا شَىْءٌ‏.‏
