The infallibility of the prophets in the system of Gharar [key] verses

The Holy Qurchr('39')an is the sacred source of all Muslims’ beliefs and deeds, and since all Muslims believe in its verses, it can unite them. But the fact that Muslims approach and understand the Quran differently has led to their discrepancy. The infallibility of the prophets constitutes one of the most controversial teachings among Muslims. Accuracy in the instruments of attaining infallibility can determine the extent of the infallibility of the prophets. The main claim of the research at hand is that if a system including the Gharar [key and definite] verses is established, the instruments and the extent of the infallibility of the prophets will be made clear in the Qurchr('39')an. The definite verses of the Qurchr('39')an say that through instruments such as bestowing transcendent knowledge, strengthening the intellect, divine success, and eliminating the dominion of Satan, it is possible to be beautified with the attribute of infallibility. The author uses library archives and follows a descriptive- analytic- method to prove his claim.
