A discussed above, a miracle is defined as “events which lie outside the productive capacity of nature”. The argument posed by Muslim Theologians and Philosophers is that if, with the finite set of Arabic linguistic tools at humanity’s disposal, there has been no effective challenge to try and imitate the Qur'an, then providing a naturalistic explanation for the Qur’an’s uniqueness is not sufficient. This is because the natural capacity of any author is able to produce the varying expressions known in the Arabic language. The development of an entirely unique expression is beyond the scope of the productive nature of any author, hence a supernatural entity, God, is the only sufficient comprehensive explanation.
