Narration of Imam Mahdi (As)
The Prophet Muhammad (p.b.u.h) said:
Allah will bring out from concealment al-Mahdi from my family and just before the day of Judgment; even if only one day were to remain in the life of the world, and he will spread on this earth justice and equity and will eradicate tyranny and oppression.
(Musnad Ahmad Ibn Hanbal, Vol. 1, P. 99)
I heard the Prophet (SAW) declare from the pulpit:
The Mahdi from among my descendants, from my family, will rise at the End of Time, while the heavens will pour rain and the earth will bring forth green grass for him. He will fill the earth with justice and equity as it is filled with tyranny and injustice.
(Bihar al-anwar, Vol. 51, P. 74; Ithbat al-hudat, Vol. 7, P. 9)
Abu al-Hujaf (RA) quotes the Prophet (SAW) saying three times :
Listen to the good news about the Mahdi ! He will rise at the time when people will be faced with severe conflict and the earth will be hit by a violent quake. He will fill the earth with justice and equity as it is filled with injustice and tyranny. He will fill the hearts of his followers with devotion and will spread justice everywhere.
(Bihar al-anwar, Vol. 51, P. 74)
The holy Prophet (SAW) said:
The world will not come to an end until a man from the descendants of Hussain (As) takes charge of the affairs of the world and fills it with justice and equity as it is filled with injustice and tyranny.
(Bihar al-anwar, Vol. 51, P. 66)
