The revelation of the Qur'an took a period of 23 years. The Qur'an is the central religious text of Islam and contains the revelations that were received by the Prophet Muhammad from Allah, the Islamic God, over a period of 23 years. The revelations were received in fragments or chapters known as surahs, which were later compiled into the complete text of the Qur'an. The process of revelation began in 610 CE when the Prophet Muhammad received his first revelation in the Cave of Hira, near Mecca, and continued until his death in 632 CE. Over the course of the 23-year period, the revelations provided guidance and instruction to the early Muslim community, addressing a range of topics including faith, morality, social issues, and governance.
