Innovation Features in Criticism in the Abbasid Age

It is known that the holy Quran has aroused the Arabs' amazement, allured and fascinated their minds since its early revelation. Especially, it is the source of challenge and inimitability. Thus, the scientists in every age of the centuries after Islam have been trying to unravel the secrets of that challenge, and reach any access to the keys that may lead to know the aspects of this miracle. Meanwhile there was a small part of people who have tried to invalidate Quran and underestimate it. They also tried to oppose it and bring the like of it, but it is far, far away. Allah, the Exalted, the Majestic said "Say: Surely, if mankind and jinn were to get together to produce the like of this Qur'an, they will never be able to produce the like of it, howsoever they might help one another." Consequently, we have seen that the theme of our paper should be relevant to the innovation in criticism in the Abbasid age, and we paid the biggest deal of our attention to criticism related to Quran inimitability, trying to show that the spirit of renewal for all of those who contributed in the writings in this area.
