this quran is not such as can be produced by other than allah on the contrary it is a confirmation of that went before it and a fuller explanation of the book wherein there is no doubt from the lord of the worlds.
وما كان هذا القرآن أن يفترى من دون الله ولكن تصديق الذي بين يديه وتفصيل الكتاب لا ريب فيه من رب العالمين
