Concept:The standardization of the Qur'an refers to the collection of its text into one uniform, authoritative version during the reign of Caliph Uthman.
Explanation:During military campaigns, Islamic soldiers from different regions recited the Qur'an in varying dialects and readings.
This created confusion and sharp disagreements about the correct recitation.
Hudhayfah b. Yamani witnessed these severe disputes while leading troops in the conquest of Armenia and Azerbaijan.
Alarmed by the division, he rushed to Caliph Uthman and strongly urged him to save the Muslim community from conflict over the Qur'an.
Following Hudhayfah's advice, Uthman ordered the compilation and standardization of the text into the Quraysh dialect.
Thus, although the actual standardization was executed by Uthman's committee, Hudhayfah b. Yamani was the key person who identified the problem and initiated the process.
Among the given options, he is the one directly connected with this historic step.
Answer:B. Hudhayfah b. Yamani
