Narrated Anas:
`Uthman called Zaid bin Thabit, `Abdullah bin Az-Zubair, Sa`id bin Al-`As and `AbdurRahman bin
Al-Harith bin Hisham, and then they wrote the manuscripts of the Holy Qur'an in the form of book in
several copies. `Uthman said to the three Quraishi persons. " If you differ with Zaid bin Thabit on any
point of the Qur'an, then write it in the language of Quraish, as the Qur'an was revealed in their
language." So they acted accordingly. (Sa`id bin Thabit was an Ansari and not from Quraish ).
