46. There is a general misunderstanding that the challenge of the Quran to produce a book, nay, a Surah like this, is in regard to its eloquent, pure and unique literary excellence. This has been the natural result of the way in which discussions have been carried on to prove the miracle of the Quran. But the Quran is far above this that it should claim to be a unique and matchless book because of its excellent diction. There is no doubt at all that it is unique and matchless in this respect also, but the real basis of its claim and challenge, that no human brain is capable of producing a book like this, is its subject matter and teachings. The Quran itself has stated at different places those aspects which are a sure proof of its revelation from Allah and the refutation of the false aspersions that it was a human invention. This has already been explained at appropriate places and will be explained in the succeeding pages. See (E.N. 26, 27 of Surah At-Toor).
