The advent of mankind’s savior is one of the important issues reflected in the form of Quranic teachings in Shiite narrative sources. These narrations of the Infallibles (the Prophet and twelve Imams of Shia), mostly, express the Mahdavi teachings of the Holy Qur'an at the level of interpretation of non-manifest meaning of the Qur'an. Due to the interpretation of dipper layer of the verses, these narrations have been more vulnerable than other Hadiths. On the other hand, a large number of the teachings of Mahdism and the relevant narrations have been expressed in the form of esoteric interpretation of Quranic verses; Therefore, to recognizing and characterize this group of narrations is of special importance. Using a descriptive-analytical method, the present research analyzes these type of narrations for the recognition of the features and characteristics that are effective to entrust a Hadith or to put doubts in it. The results of the research show that the interpretive narrations that express clear examples of divine verses reassure us; and other narrations, in terms of injurious content or double weakness of the documentation, would be disallowed.
