In this article, this issue is analyzed with an analytical method and by referring to library sources, in which, in addition to stating the conditions of the miracle (especially tahaddi), various views regarding the reason for the human inability to bring a surah or a book like the Qur'an are explained. According to the findings of the research, mathematical calculations regarding the number of probable sentences (fasih & baligh, eloquent and fluuent) (from Arabic words) show that in addition to the two theories of "sarfeh" (disability of man by God) and the opposite view (human natural disability), is a more accurate point of view that believes in the field. it, therefore, can be said that the reason for human inability to bring the example of the Qur'an is actually the lack of a text of its size, not his own lack of ability and, in fact, the challenge of the Qur'an is the discovery of the lack of such text.
