7. The challenge thrown by the Quran.

The following verses of the Quran (2:23, 10:38, 11:13, 17:88, 28:49, 52:34) challenge anyone to bring out a similar book. The Quran was revealed to Prophet Muhammad an illiterate, with a few learned people around with high literary caliber and poetic knowledge of the time. 

The scripture that was revealed to an illiterate surpassed the best literary works of the day and impeccable truth. Hence the Quran, a literary work of this high caliber as being brought out by an illiterate, challenges the learned men of the times to bring out a similar book. This challenge posed to the entire mankind still stands with no takers. Hence these verses of the Quran stand to prove as God’s words.
