Regarding the unlimited divine grace, one of the important points in eschatology is pagan's eternal staying in the hellfire. This point has been mentioned in the explicit wordings of Quran as well as traditions. On the other hand, logical reasoning and mystical findings have something different to say. In this paper, when presenting the important reasons of the both agreed and disagreed with views, we have mentioned Sadra's view. He, by means of his theory of pagans' natural change, tries to make these two seemingly contradictions in harmony with the help of Quran, reasoning and mysticism. Finally, he, using a mystical exploration, seems to have found a tendency toward the theory of eternal staying in torture. Then, it should be said that neither reason nor mysticism can solve the problem, therefore, it remains to say that only Quran can be relied on in the field.
