Which Caliph ordered the official compilation and standardized distribution of the Holy Quran (Mus’haf al-Uthmani)?

Explanation

Hazrat Uthman ibn Affan (RA), the 3rd Rightly Guided Caliph, commissioned a committee headed by Zayd ibn Thabit (RA) to produce standardized copies of the Quran in the Quraishi dialect to prevent recitation discrepancies across expanding territories. Hence, he is titled ‘Jami-ul-Quran’. Remember that the initial single-volume compilation was conducted during the caliphate of Hazrat Abu Bakr (RA).
