Quran or Koran, is the central religious text of Islam, which Muslims believe to be a revelation from God (Allah). It is widely regarded as the finest work in classical Arabic literature Slightly shorter than the New Testament, it is organized in 114 chapters (Arabic: سورة sūrah, plural سور suwar). Muslims believe that 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. Muslims regard 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. The word “Quran” occurs some 70 times in the Quran’s text, and other names and words are also said to refer to the Quran It is thought by Muslims to be not simply divinely inspired, but the literal word of God.
