Who is Imam Mahdi?
Imam Mahdi (aj) is the twelfth Imam of Shia and he is the last chain of the Purified Imams (as) and the successors of the Holy Prophet(sa). He was born on Friday the 15th of Shaban 255 A.H. in the city of Samarrah.
His great father is Imam Hasan al-Askari (pbuh). His beloved mother is Nargis Khatoon (ra).From her father’s side, she was the descendant of the Cyesar of Rome and from her mother’s side, she was descendant from shamoon the vicegerant of Hazrat Isa (as).
He has the same name and kunniyat as the Holy Prophet (sa). His titles are Mahdi, Hujjat, Qaem, Montazer, Sahibuzzaman and Khalaf al-saleh and the other names we heard.
The Abbasid rulers wanted to kill a boy with the similarity of Imam Mahdi; because they were aware of traditions of the Holy Prophet (sa) about imam Mahdi.
They knew the son of Imam Hasan al-Askari (as) should be the same Mahdi; then they planned to eliminate the child when he is born.
Because of this reason his birth was kept a secret. So no one knew of the existence of Imam Mahdi except for the trusted of his father’s followers.
Abu Ghanim says:
“Abu Muhammad (as) has a son whose name is Muhammad.” On the third day of his birth he brought him before his companions and said:
“After me he is your Master of the affair, he is my successor, he is the same ‘Qaem’, who is awaited by alt When the earth will be fraught with injustice and oppression then he will reappear and fill the earth with justice and righteousness.” (Kamaaluddin Vol. 2 Pg. 431)
There are two occultations for Imam Mahdi. One is short and the other is in the long time. In the short concealment only the special shias will know of his situation. And in the longer one, only his trustworthy followers will know about his place and situation.
So far he is in the long concealment and his followers are waiting for him and praying for his coming. Also we are waiting for a beautiful life in his time.
The Prophet (S) said: “Even if the entire duration of the world’s existence has already been exhausted and only one day is left (before the day of judgment), Allah will expand that day to such a length of time, as to accommodate the kingdom of a person from my Ahlul-Bayt who will be called by my name. He will fill out the earth with peace and justice as it will have been full of injustice and tyranny (by then).”
(Musnad Ahmad Ibn Hanbal, v1, pp 84,376; V3, p63)
