حَدَّثَنَا أَبُو الْيَمَانِ ، حَدَّثَنَا شُعَيْبٌ ، عَنِ الزُّهْرِيِّ ، وَأَخْبَرَنِي أَنَسُ بْنُ مَالِكٍ ، قَالَ : فَأَمَرَ عُثْمَانُ زَيْدَ بْنَ ثَابِتٍ وسَعِيدَ بْنَ الْعَاصِ وعَبْدَ اللَّهِ بْنَ الزُّبَيْرِ وعَبْدَ الرَّحْمَنِ بْنَ الْحَارِثِ بْنِ هِشَامٍ أَنْ يَنْسَخُوهَا فِي الْمَصَاحِفِ ، وَقَالَ لَهُمْ : " إِذَا اخْتَلَفْتُمْ أَنْتُمْ وزَيْدُ بْنُ ثَابِتٍ فِي عَرَبِيَّةٍ مِنْ عَرَبِيَّةِ الْقُرْآنِ ، فَاكْتُبُوهَا بِلِسَانِ قُرَيْشٍ ، فَإِنَّ الْقُرْآنَ أُنْزِلَ بِلِسَانِهِمْ فَفَعَلُوا " .
Narrated Anas bin Malik: (The Caliph `Uthman ordered Zaid bin Thabit, Sa`id bin Al-As, `Abdullah bin Az-Zubair and `Abdur- Rahman bin Al-Harith bin Hisham to write the Qur'an in the form of a book (Mushafs) and said to them. "In case you disagree with Zaid bin Thabit (Al-Ansari) regarding any dialectic Arabic utterance of the Qur'an, then write it in the dialect of Quraish, for the Qur'an was revealed in this dialect." So they did it.
