Challenge Of Quran?
Man has no knowledge of the metaphysical world nor is capable to know it, no matter how long he may live. He cannot know what will happen tomorrow let alone methaphysical world which tells how and why the world came into existence and to what end they are heading. There is God and what He is and what are his attributes and what He desires. So there is not chance to create or compose a Quranic surah. It is not just jargon but of a unique stylistic way of composition and of knowledge which is not human.
