The Quran was not authored by any human being; it is the actual word of God revealed to the Prophet Muhammad through the angel Gabriel. The process of revelation began in 610 AD and continued over 23 years. The Prophet Muhammad served as the receiver of this divine message, and he did not write it himself. He had scribes who recorded the revelations as they were revealed, ensuring that the Quran was preserved in both written and memorized forms. After the Prophet's death, the compilation of the Quran into its current form was carried out under the caliphate of Abu Bakr and later Uthman, who standardized the text to ensure its preservation. Thus, the Quran is viewed as a divine scripture, revealed on Prophet Muhammad and recorded by his Companions.
