this quran could not have been produced by anyone other than god. in fact it is a confirmation of what preceded it and an elaboration of the book. there is no doubt about it—it is from the lord of the universe.
وما كان هذا القرآن أن يفترى من دون الله ولكن تصديق الذي بين يديه وتفصيل الكتاب لا ريب فيه من رب العالمين
