The Quran was orally revealed by God to the final prophet, Muhammad, through the archangel Gabriel (Jibril), incrementally over a period of some 23 years, beginning on 22 December 609 CE, when Muhammad was 40, and concluding in 632, the year of his death.

The Quran as Muhammad's most important miracle, a proof of his prophethood, and the culmination of a series of divine messages starting with those revealed to Adam, including the Tawrah (Torah), the Zabur ("Psalms") and the Injil ("Gospel"), and ending with Muhammad's revelation.
