The existence of the Mahdi and that he will emerge in the end times, that he is from the family of the Prophet (saas) and the sons of Fatima, are explained by hadith at the level of tewatur and there is no sense in denying these hadith. It has been proved by clear and explicit hadith that exceed the level of tewatur that the Mahdi is from the predecessors of Fatima, that he will emerge before the end of the world, that he will bring justice and peace to this world which is full of injustice and oppression, that Jesus (as) will descend from the sky in his time and pray in his leadership.
(Serif Muhammed b. Resul Berazenci Medeni, el-isae, s.184 ve 305/ Mehdilik ve Imam Mehdi (Mahdism and Imam Mahdi), p.328)
In a hadith widely regarded as authentic, Muhammad 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, God will expand that day to such a length of time, as to accommodate the kingdom of a person out of Ahl al-Bayt who will be called by my name. He will then fill the Earth with peace and justice as it will have been filled with injustice and tyranny before then."
-Sahih Tirmidhi, V2, P86, V9, P74-75.
The Mahdi, according to Shi'ite tradition, will arise at some point before the day of judgement, institute a kingdom of justice, and will in the last days fight alongside the returned Jesus against the Dajjal, the Antichrist.
Thus just before the Second Coming of Jesus, Mahdi will appear and will establish a righteous kingdom.
