Who was the third Caliph of Islam, known for standardizing the Quranic text?

Explanation

– Uthman ibn Affan (RA) served as the third Caliph of Islam, ruling from 23 AH to 35 AH, and is particularly noted for standardizing the Quranic text into a single official script distributed across the empire to resolve regional recitation disputes.
– His caliphate also saw continued territorial expansion, though it faced increasing internal political challenges in its later years.
– For exams, note that Uthman (RA) was given the honorific title Dhun-Nurayn, meaning ‘possessor of the two lights,’ due to his marriage to two of the Prophet’s daughters successively.
