We will say: We have answered this question in Talkhis Shafi in detail. In brief, if Allah knows that some narrations pertinent to the binding religious laws have not reached people in a situation of Imam’s dissimulation (Taqayyah) and fear from his enemies, He will annul their imperativeness from the people, who do not have access to them. However, if consensus proves that religious duties are continuously binding over all people of the Ummah until Judgment Day, it can be inferred that if such an interruption in transmission of narrations occurs, it will be only in a situation when the Imam is able to appear and make declarations and issue warnings.
