It is narrated from Hazrat Abu Saeed Khudri that the Messenger of Allah, peace and blessings be upon him, said: There will be a Mahdi in my Ummah. Whether his age is long or short, he will rule over the earth for seven years, or eight years, or nine years. Then he will fill the earth with justice and fairness just as it had been filled with oppression. And then rain will descend from the sky and the earth will bring forth its blessings. The Prophet, peace and blessings be upon him, said: My Ummah will live a life in his time such as it has never lived before.

It is narrated from Hazrat Abu Saeed that he said: The Messenger of Allah, peace and blessings be upon him, said: A man from among my Ahl al-Bayt will appear at the end of times when tribulations become manifest. His giving will be full and generous.

It is narrated from Hazrat Abu Saeed that the Messenger of Allah, peace and blessings be upon him, said: In the last era, such caliphs will emerge who will give rights without measure.

It is narrated from Hazrat Ibn Abbas (may Allah be pleased with them both) that he said: Days and nights will not pass until a young man from among us, the Ahl al-Bayt, will become a leader, whom trials will not confuse, nor will he confuse the trials. The narrator said: We asked, "O Abu al-Abbas, will your elders be unable to meet him and your youth will find him?" He replied: "That is Allah's command; He grants it to whom He wills."

It is narrated from Abdullah bin Abbas, he said: Among us there will be three men; among us will be the Saffah, among us will be the Mansur, and among us will be the Mahdi.

It is narrated from Hazrat Abdullah bin Umar that he said: O people of Kufa, you are the most fortunate among the people because of Mahdi.

It is narrated from Hazrat Ali (may Allah be pleased with him) that he reported from the Prophet (peace and blessings be upon him) that he said: Mahdi will be from among us, that is, from the Ahl al-Bayt. In one night, Allah Almighty will grant him the ability (for leadership and caliphate).

A narration similar to the above-mentioned report is transmitted from Hazrat Ali (may Allah be pleased with him), and Hazrat Ali (may Allah be pleased with him) did not transmit it as a marfu’ (attributed directly to the Prophet).

It is narrated from Hazrat Mujahid that he said: Mahdi is Isa ibn Maryam. (Note: In this narration, Isa is called Mahdi. This does not necessarily negate the Mahdi whose name is Muhammad bin Abdullah, because Isa is among the rightly guided people and the group of prophets who possess infallibility and high status. Therefore, being Mahdi here is in the linguistic sense. Otherwise, the fact that Isa and Mahdi are two separate personalities is established as clearly as daylight by numerous authentic and mutawatir ahadith.)

It is narrated from Hazrat Abdullah that the Messenger of Allah, peace and blessings be upon him, said: The world will not end until Allah sends a man from my Ahl al-Bayt whose name will be in accordance with my name (referring to Hazrat Mahdi, whose name will be Muhammad bin Abdullah).
