QUICK FACTS
At a Glance
A concise reference to the identity, lineage and historical periods traditionally associated with Imam Muhammad al-Mahdi.
In the traditional Twelve-Imam succession.
NOBLE LINEAGE
The Son of Imam Hassan al-Askari
From Imam Hassan al-Askari
Imam Muhammad al-Mahdi is traditionally identified as the son of Imam Hassan al-Askari, the eleventh Imam, and a descendant of Imam Hussain ibn Ali through the preceding Imams. His lineage connects the final Imam with the household of Prophet Muhammad (S.A.W.W.) through Lady Fatema al-Zahra and Imam Ali (A.S.).
A Life Under Surveillance
His father lived in Samarra under close Abbasid surveillance. Traditional accounts therefore emphasize discretion, protection and a limited circle who were said to have known of the child.
THE BIRTH
A Birth Kept from Public Eyes
Traditional biographical accounts place his birth in Samarra on 15 Sha'ban 255 AH, while some historical presentations give 256 AH. The traditions describe a young child whose existence was known to a limited circle because the Abbasid authorities were understood to be watching the household of Imam Hassan al-Askari.
HIS NAMES & TITLES
Names that express guidance, truth and the awaited age
Al-Mahdi
“The guided one” — a title expressing guidance and right direction.
Al-Qa'im
A title associated with rising or standing for the truth.
Sahib al-Zaman
Commonly rendered as “Master of the Age.”
Imam al-Asr
A devotional title connected with the age in which he is awaited.
THE IMAMATE
Leadership in an Age of Hiddenness
After the death of Imam Hassan al-Askari in 260 AH, traditional accounts identify Muhammad al-Mahdi as assuming the position of Imam while still very young. Unlike the preceding Imams, his public life was not lived openly. The central feature of his historical memory is therefore a long period in which guidance and religious hope were preserved through a hidden existence.
THE OCCULTATION
Two Periods of Ghaybah
Minor Occultation
260–329 AH. Communication was traditionally associated with four successive special deputies.
Major Occultation
From 329 AH onward. The Imam is understood to remain hidden until the time appointed by Allah.
THE FOUR SPECIAL DEPUTIES
Four Representatives of the Minor Occultation
Uthman ibn Sa'id al-Amri
Traditionally regarded as the first special deputy and a trusted representative of Imam Hassan al-Askari before serving the young Imam al-Mahdi.
Muhammad ibn Uthman
He succeeded his father and served for many years, maintaining the channel of communication during the Minor Occultation.
Husayn ibn Ruh al-Nawbakhti
A respected figure who succeeded Muhammad ibn Uthman and became the third special deputy.
Ali ibn Muhammad al-Samarri
The fourth and final special deputy. His death in 329 AH traditionally marks the end of the Minor Occultation.
THE AWAITED REAPPEARANCE
Hope, Justice and the Enduring Promise
Hope without a speculative timetable
In Islamic tradition, al-Mahdi is associated with a future reappearance in which justice and righteousness will prevail after a period of widespread injustice. The exact signs and chronology of that event are described differently across bodies of Islamic scholarship, so this page presents the central theme carefully: hope in divine justice, moral steadfastness and the expectation of a righteous renewal rather than a speculative timetable.
HIS LEGACY
A Legacy of Patience and Hope
The enduring legacy associated with Imam Muhammad al-Mahdi is the discipline of hope: to remain faithful, patient and committed to justice even when the promised resolution cannot be seen. His story links the Ahl al-Bayt with a vision of moral renewal and reminds believers that justice is not merely an aspiration but a responsibility to pursue in one's own conduct.
