To ensure the authenticity of the compiled text of the Holy Qur'ān, extracts written on various materials were cross-checked with texts
Written by Zayd bin Thābit
recalled from memory by early memorizers
delivered by angel Jirīl to the Prophet (S.A.W)
written by the Prophet (S.A.W) himself
Correct answer is B
Muhammad (SAW) did not write Quran as he didn't know how to write. According to tradition, several of Prophet Muhammad's companions served as scribes and recorded the revelations. Shortly after his death, the Quran was compiled by the companions, who had written down or memorized parts of it.Caliph Uthman established a standard version, now known as the Uthmanic codex, which is generally considered the archetype of the Quran known today.
