The Qur'an, therefore, invited the Arabian orators of that time to reply to even one of the shortest of the Suras. It challenged them with the decree of:
And if you are in doubt about what We have revealed to Our servant,
then produce a Sura resembling it.5
It also said: "If you do not believe, you shall be damned and shall go to Hell." It provoked them intensely. It smashed their pride in fearsome manner. It was contemptuous of their arrogant minds. It condemned them firstly to eternal extinction and then to eternal extinction in Hell, as well as to worldly extinction. It said: "Either dispute me, or you and your property shall perish."
If it had been possible to dispute the Qur'an, is it at all possible that while there was an easy solution like disputing it with one or two lines and nullifying the claim, they should have chosen the most dangerous and most difficult, the way of war? Yes, is it at all possible that that clever people, that politically-minded nation, who at one time were to govern the world through politics, should have abandoned the shortest, easiest, and most light way, and chosen the most dangerous, which was going to cast their lives and all their property into peril? For if their literary figures had been able to dispute it with a few words, the Qur'an would have given up its claim, and they would have been saved from material and moral disaster. Whereas they chose a perilous, lengthy road like war. That means it was not possible to dispute in by word; it was impossible, so they were compelled to fight it with the sword.
Furthermore, there are two compelling reasons for the Qur'an being imitated. The first is its enemies' ambition to dispute it, the other, its friends' pleasure at imitating it. Impelled by these, millions of books in Arabic have been written, but not one of them resembles the Qur'an. Whether learned or ignorant, whoever looks at it and at them is bound to say: "The Qur'an does not resemble these. Not one of them has been able to imitate it." The Qur'an is therefore either inferior to all of them, and according to the consensus of friend and foe alike, this is completely non-valid and impossible, or the Qur'an is superior to all of them.
