this quran is not such as could have been produced by anyone but god. it fulfills that which came before it and gives a fuller explanation of the revelations. 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
