Answer:
The holy book for Muslims, the members of Islam, is called the Qur'an (literally: recitation). Muslims believe that the Qur'an was revealed by the angel جبريل, Jibrīl (Gabriel) over a period of years and that it was written down by followers of Muhammad. For Mulsims, the original text in Arabic is the final revelation of God. As every part of the Qur'an is believed to be as God wishes, translations are not, strictly speaking, as authentic as the original text. (See related links)
