Sahih al-Bukhari 4530
Narrated Ibn Az-Zubair:
I said to `Uthman bin `Affan (while he was collecting the Qur'an) regarding the Verse:-- "Those of 
you who die and leave wives ..." (2.240) "This Verse was abrogated by an other Verse. So why 
should you write it? (Or leave it in the Qur'an)?" `Uthman said. "O son of my brother! I will not shift 
anything of it from its place."
حَدَّثَنِي أُمَيَّةُ بْنُ بِسْطَامٍ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ حَبِيبٍ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، قَالَ ابْنُ الزُّبَيْرِ قُلْتُ لِعُثْمَانَ بْنِ عَفَّانَ ‏{‏وَالَّذِينَ يُتَوَفَّوْنَ مِنْكُمْ وَيَذَرُونَ أَزْوَاجًا‏}‏ قَالَ قَدْ نَسَخَتْهَا الآيَةُ الأُخْرَى فَلِمَ تَكْتُبُهَا أَوْ تَدَعُهَا قَالَ يَا ابْنَ أَخِي، لاَ أُغَيِّرُ شَيْئًا مِنْهُ مِنْ مَكَانِهِ‏.‏
