Qur'ani iliendelea kusomwa kwa namna saba hadi katikati ya utawala wa Khalifa ‘Uthmaan, wakati mkanganyiko ulipoibuka katika majimbo ya mbali kuhusu usomaji wa Qur'ani. Baadhi ya makabila ya Kiarabu yalianza kujivunia ubora wa visomo vyao, na ushindani ukaanza kukua. Wakati huo huo, baadhi ya Waislamu wapya nao walianza kuchanganya namna mbalimbali kwa sababu ya ujinga. Khalifa ‘Uthmaan aliamua kutengeneza nakala rasmi za Qur'ani kwa lahaja ya Quraysh, na kuzituma pamoja na wasomaji wa Qur'ani katika vituo vikuu vya Uislamu. Uamuzi huu uliidhinishwa na masahaba wote, na nakala zote zisizo rasmi za Qur'ani ziliharibiwa. Baada ya kusambazwa kwa nakala rasmi, lahaja nyingine zote ziliachwa, na Qur'ani ikaanza kusomwa kwa lahaja moja tu. Hivyo, Qur'ani inayopatikana duniani kote leo imeandikwa na kusomwa kwa lahaja ya Quraysh pekee.29

The Qur’aan continued to be read according to the seven forms until midway through Caliph ‘Uthmaan’s rule, when some confusion arose in other outlying provinces concerning the Qur’aan’s recitation. Some Arabic tribes had begun to boast about the superiority of their readings and a rivalry began to develop. At the same time, some new Muslims also began mixing the various forms out of ignorance. Caliph ‘Uthmaan decided to make official copies of the Qur’aan according to the dialect of Quraysh and send them along with Qur’aanic reciters to the major centers of Islaam. This decision was approved by all of the sahaabah, and all unofficial copies of the Qur’aan were destroyed. Following the distribution of the official copies, all the other dialects were dropped and the Qur’aan began to be read in only one dialect. Thus, the Qur’aan which is available throughout the world today is written and recited only according to the dialect of the Quraysh.29
