In the Qur'anic view, the main mission of the prophets and their heavenly books is preaching. If the Qur'an, in some cases, deals with any subject, it has only a preaching approach. If we look at the Qur'an as a book of preaching, we sometimes come across verses that seem untrue: such as the imprisonment of a people called Gog and Magog behind a dam until the Day of Judgment or the dropping of meteors to drive demons out of the sky. Allameh Tabatabai considers these two as untrue and considers the relevant verses as permissible. However, all the commentators of the Qur'an, in the last fourteen hundred years, have all considered these verses to be true, and it is a difficult claim to claim that they misunderstood the Qur'an. The competitive theory, which is discussed in this article, is that those are myths, and in preaching, there is nothing wrong with using the myths of the audience as a tool. This theory, while leaving the verses of the Qur'an on their apparent meaning that all commentators have understood over fourteen centuries, also proves the legitimacy of the Qur'an.
