There is not an explicit verse about the last Imam, his holiness the Imam Mahdi and Mahdaviat. But according to the abundant narrations which are in hand in farighain resources as interpretation and application, one could consider Mahdaviat and Monjigeraei as one of the epistemic manifestations of Quran which has been descended for human guidance and salvation. The 4th to 8th verses of Asra' surah are among the verses which deal with the advent of his holiness the Imam Mahdi, in an interpretive way and draw this concept out from the time of the children of Israel and Jewish religion to the similar events in Islam. These verses point out to ups and downs of the children of Israel 's history and their ascending and descending ethics as well as their corruption and punishment. These verses, along with the narrations which consider the trail of the last prophet's nation similar to the tradition in the children of Israel time, bring about more awareness and care against seditions before the advent of Imam Mahdi and also lead to loyalty, more intellectual preparation and expectation to the promised age of the savior and the emergence of the reformer and the government of his holiness.
