Elaborating the negative role of extraordinary affairs in detecting false claimants

One of the important challenges in the path of Mahdaviyat is the existence of false claimants of Mahdaviyat. Understanding the claimants at the beginning and the on time response has a significant impact in counteracting these diversions. In our traditions, It has been mentioned extraordinary affairs such as having a miracle, a lifetime, knowledge, a heavenly voice, Dip on the ground and etc... about the Imam of the Age. Among the functions of these extraordinary affairs are their epistemic and negative functions. The failure of the false claimant to do a miracle is something in which, his non-imamate can be concluded. One who does not have extraordinary longevity can not be Imam of the time. One who does not have vast knowledge and infallibility can not be an Imam .One who does not carry prophets heritages and Jesus Christ does not come to confirm him and help him is not Imam Mahdi(aj).
