Muslim believes in all scriptures and revelations of God, as they were complete and in their original versions. Muslims believe in the original scriptures that were given to previous messengers; for example David received the Psalms (Zabur), Moses the Torah (Taurat) and Jesus the Gospel (Injeel). However, the previous scriptures do not exist today in the original form in which they were revealed.
The Quran is the last testament in the series of divine revelations from God, and Muslims recite and turn to it for guidance in all aspects of their life. It comprises the unaltered and direct words of God, revealed through the Angel Gabriel, to the final Prophet, Muhammad, peace be upon him (pbuh), some 1400 years ago. The Quran is unique because it is the only revealed book that exists today in the precise form and content in which it was originally revealed.
The Quran is unrivaled in its recording and preservation. The astonishing fact about this scripture is that it has remainedcompletely unchangedover the past fourteen centuries, a fact that is attested to by both non-Muslim and Muslim scholars alike. There are no versions of the Quran and every copy in the world remains identical, word for word in its original language Arabic. Muslims to this day continue to emphasize the importance of memorizing the Quran word by word, as a whole or in part, recognizing that it is the Speech of God and not a book written by Muhammad (pbuh), as sometimes erroneously thought.
