The Holy Qur'an is a Miracle

Sura Al-Baqarah

23. "And if you are in doubt of what We have sent down to Our (faithful) Servant (Muhammad), then bring forth one Sura the like thereof, and call your witnesses other than Allah, if you are truthful."

24. "And if you do not do so, and you will never do it, then fear the Fire whose fuel is People and Stones, prepared for the infidels."

Commentary :

After Allah (s.w.t.) explains the state of the hypocrite and disbelievers, and, through the creation of the heaven and the earth, sending down rain and growing plants on the ground, proves the existence of the Creator and Cherisher of the universe, He begins to validate the rightfulness of the Holy Qur'an and the truthfulness of His Messenger.

In order to show everyone the miraculousness of the Qur'an with clear evidence,according to one's portion of wit and understanding, that the Qur'an will be an argument for all, Allah confirms the prophethood of Prophet Muhammad (p.b.u.h.) and the authenticity of the Holy Qur'an by suggesting a challenge, a direct confrontation, not only to all the contemporaries of the Prophet (p.b.u.h.) but also to men in all ages. " And if you are in doubt of what We have sent down to Our (faithful) Servant (Muhammad),..."

It addresses all the rejectors, with a concrete test, saying that if you imagine that the Qur'an, which has been sent down from Pure Holiness to the chosen servant of Allah in the form of statements and with the combination of ordinary alphabetical letters, is not from Him and it is the word of a human, then since outwardly you are in the same state from the point of being a human as the Prophet of Islam (p.b.u.h.) is, you should be able to produce a Sura like that of the Qur'an and call your own witnesses that are like you, the disbelievers of the Qur'an. You would compare your evidence with one of the Suras of the Qur'an, even if it be a small one such as Sura Kauthar and the like. If those two were similar in comparison in all their qualities, merits and privileges, you could rightfully reject the legitimacy of the Qur'an.

The disbelievers and pagan Arabs, who were the masters of literature and eloquence, refrained from accepting this challenge despite their pride and haughtiness in eloquence and avoided the competition. Therefore, inevitably, they turned the literary contest into a bloody battle. Thus, getting killed was easier for them than being disgraced and defeated in a literary contest. The Arab literature became helpless and meagre against the challenge of the Qur'an. Neither those who lived at the time of the Qur'an's revelation, nor the people born in the centuries after that could bring anything like this Holy Book,  or could do anything against it, inspite of trying with their utmost strength. They were thus forced to retreat after exerting utmost efforts.
