When the revelations of the Quran began, the Most Noble Messenger clearly proclaimed the Quran to be the word of God, and said it was impossible for any human being to duplicate it.

If anyone disagreed, he ought to make an attempt to copy it, and should feel free to seek help from any source in doing so. None was able to take up this challenge and produce even a short surah similar to the Quran.

The Qur'an remains a book of inimitable quality, not only from a
linguistic but also from an intellectual point of view. When Muhammad was challenged by his fellow countrymen to present a miracle, in keeping with the tradition of other prophets, he presented the Qur'an to them.

The inimitability of the Qur'an is repeatedly emphasized in the Holy Book itself. The Quran issued a challenge not only to the contemporaries of
the Prophet but also to men in all ages. In order to demonstrate the incapacity and impotence of people to imitate it, it issued the following universal proclamation:



"Were all mankind to come together and wish to produce the like of the Quran, they would never succeed, however much they aided each other". (17:88)
