The Mahdi is not to be born in the distant future.
The Mahdi is not to be born in the distant future. He is already living amongst us and shares our joys and sorrows: His appearance will mean not only the materialization of an Islamic aspiration, but will also be the realization of a hope cherished by the entire humanity. Prof. Henry Corbin of Sorbonne University, says: "To my mind the Shi'ite is the only sect which has preserved and perpetuated the link of Divine guidance between man and God through its belief in the Imamate.
According to the Jews the Prophethood, a real link between man and God, came to an end with Moses. They do not believe in the Prophethood of Jesus and Muhammad. The Christians too, do not go beyond Jesus. The Sunnite sect has also stopped at the and believes that the link between man and God has been severed with the end of the Prophethood". It is only the Twelver Shi'ah who believe that the link still exists through the Mahdi and will continue to exist forever.
It is hardly necessary to give an explanation as to why the Mahdi disappeared immediately after assuming the Imamate. Let it suffice to say that Allah in His Divine Wisdom ordained so. In the meantime it is the duty of all the Muslims, especially the Shi'ah, to strive steadfastly for the creation of the proper atmosphere and the right climate for the establishment of a world order based on justice, virtue and piety.
They should not only mould their individual lives according to the teachings and high ideals of Islam, but they should also bend their efforts to set up the Islamic order on the collective and communal level. They should devote themselves to the service of the faith and be prepared to receive the Awaited Saviour. That is what was meant by the Imams when they exhorted the Muslims to keep on waiting for the Mahdi.
An authentic and universally accepted Hadith (tradition) reports the holy Prophet of Islam (Peace and benediction be upon him and his infallible progeny) to have said explicitly on several occasions that he would be followed by twelve Amirs, [^1] (according to another version, twelve caliphs) the first of them being Ali and the last Mahdi.
[^2] According to another reliable tradition he pinpointed the personality to Imam Mahdi when he said that the Mahdi would be a descendant of Imam Husayn in his ninth generation.[^3] In certain other traditions the holy Prophet referred, in clear terms, to the last Imam's mission and narrated the events connected with his occultation and reappearance.
