Uthmanic codex

Wikipedia extract

The Uthmanic codex —according to historical accounts— is the only edition of the Quran compiled by the third Rashidun caliph Uthman ibn Affan. He ordered it to be copied and the copies sent to Islamic countries, after the death of Muhammad. The Quran was collected in a single book by order of the first caliph Abu Bakr al-Siddiq, and when the caliphate was handed over to Uthman ibn Affan, the Islamic conquests expanded and the companions spread in the conquered countries, teaching people the Quran and how to read its different readings. When the Companion Hudhayfah ibn al-Yaman noticed that Muslims differed in reading and some of this difference was tinged with melody, he told the Caliph about it, and Uthman ordered that the Quran be collected in one way. He sent Hafsa bint Umar to allow him to use the copy of the Quran in her possession to use it as a reference, and Uthman ordered several copies of the Quran to unify the reading and ordered them to be distributed to the Muslim countries, and ordered the destruction of anything that contradicts that Quran.
