These ayahs are a proof that the Quran is the Word of Allah. (1) The Quran is such a miracle in regard to its language, style, arguments, themes, topics, teachings and prophecies that it is beyond any human power to produce the like of it, as if to say, "You say that a man has invented this but We challenge that even the whole of mankind combined cannot produce a Book like this: nay, even if the jinns, whom the mushriks worship as deities and whom this Book openly attacks, should come to the help of the disbelievers, they cannot produce a Book like this to refute this challenge. (2) As regards to the charge that Muhammad (peace be upon him) has himself invented this Book, the Quran refutes their claim, as if to say” Muhammad is one of you and not a foreigner. He has lived among you for forty years before the revelation of the Quran. Did you ever hear words like those of the Quran from him even a day before his claim of Prophethood, or did you ever hear him discussing themes and problems contained in the Quran? If you consider the matter from this point of view, it will become obvious to you that the sudden change which has come about in the language, ideas, information, style and the way of thinking of Muhammad, could not take place without divine guidance. (3) Can you not see that after the recital of the Quran, he does not disappear but lives among you? You hear other things than the Quran from him. Do you not notice that the distinction between the two different styles of expression is so obvious that no man can successfully adopt the two styles at one and the same time. The distinction can also be noticed, even today, between the language of the Quran and that of the traditions of the Prophet (peace be upon him). Anyone well versed in the Arabic language and literature notices the difference which is so marked that one can categorically say that these modes of expression cannot belong to one and the same person.
