<P> Muslims believe that the Quran was verbally revealed by God to Muhammad through the angel Gabriel ( Jibril ) , gradually over a period of approximately 23 years , beginning on 22 December 609 CE , when Muhammad was 40 , and concluding in 632 , the year of his death . Muslims regard the Quran as the most important miracle of Muhammad , a proof of his prophethood , and the culmination of a series of divine messages that started with the messages revealed to Adam and ended with Muhammad . The word `` Quran '' occurs some 70 times in the text of the Quran , although different names and words are also said to be references to the Quran . </P>
