The perfect state of preservation singles out the Quran from its predecessors as a unique vehicle for divine guidance and salvation, one, which will retain its validity until the Day of Judgment. Apart from this fact, the author discusses the Quran in itself being a proof that it is the Book of God. In The Quran: An Abiding Wonder Maulana Wahiduddin Khan briefly discusses two aspects of the Qur’an: firstly, its being in itself a proof that it is the Book of God; secondly its complete preservation in its original form, as revealed to the Arab Prophet Muhammad in the seventh century Hijrah. The author explains that what distinguishes the sacred Islamic text from its forerunners is not just that it is complete and the other revealed books: incomplete. It is that the text of the Qur’an has never been tampered with, whereas all the other Books have long ago lost their original form and. content, which has meant a serious loss of authenticity. It is this characteristic of the Qur’an-its perfect state of preservation-which singles it out from its predecessors as a unique vehicle for divine guidance and salvation, one which will retain its validity until Doomsday.
