Imam Hasan al-Askari

Hasan ibn Ali ibn Muhammad was born in Medina into the Husayni line of the Prophet’s family. Sources differ over the exact date: some give 231 AH/845–846 CE, while Imamite authorities commonly report 232 AH/846–847 CE and differ over the month. His mother is protected in this registry as Hudayth; historical works also transmit the names Sawsan and Salil. The variation is best understood as different names or designations for the same respected mother rather than evidence for several separate persons.

During his childhood, Hasan accompanied his father, Ali al-Hadi, when the Abbasid caliph al-Mutawakkil summoned the family from Medina to Samarra in 233 AH/847–848 CE or 234 AH/848–849 CE. They lived in the district known as al-Askar, the military quarter of the Abbasid capital, from which both father and son acquired the designation al-Askari. The move placed the household close to the court but also under continuing political observation.

When Ali al-Hadi died in 254 AH/868 CE, Imamite sources state that he had designated Hasan as his successor. In Twelver doctrine, Hasan al-Askari therefore became the eleventh Imam. Other Muslim biographical traditions acknowledge his noble lineage and residence in Samarra without accepting the full Twelver doctrine of divinely designated imamate. A neutral account must preserve both the historical person and the school-specific meaning attached to his leadership.

His period of leadership coincided with the Abbasid caliphs al-Mu'tazz, al-Muhtadi, and al-Mu'tamid. Sources describe restrictions on his movement, summons to the authorities, and at least a period of imprisonment. The available evidence does not support turning every year of his Samarran life into continuous formal imprisonment, but it does show that access to him was controlled and that the authorities regarded the Alid household as politically sensitive.

These restrictions encouraged reliance on a network of trusted agents. A historical study of the Imamite organization records Uthman ibn Sa'id al-Umari as an agent of both Ali al-Hadi and Hasan al-Askari, and describes letters coordinating representatives in Rayy, Bayhaq, Nishapur, and other regions. The agents transmitted questions, guidance, and religious payments. This network was not merely a financial channel; it enabled dispersed communities to maintain disciplined contact when open public access to the Imam was difficult.

A substantial portion of al-Askari’s preserved legacy consists of letters, answers, and ethical maxims. Tuhaf al-Uqul transmits a long message to Ishaq ibn Isma'il al-Nishapuri and a collection of concise counsels. They emphasize gratitude, self-control, private rather than humiliating public advice, avoidance of pointless dispute and excessive joking, patience in adversity, and the moral responsibility of religious knowledge. These reports belong to the Imamite literary tradition and should be presented as transmitted teachings, not as independently authenticated verbatim recordings in every case.

Al-Kafi's biographical chapter preserves a notable report from Ahmad ibn Ubayd Allah ibn Khaqan, an Abbasid official presented in the account as hostile to the Alids. Despite that background, he described Hasan al-Askari as distinguished in guidance, composure, chastity, nobility, generosity, worship and good character, and said that members of Banu Hashim, commanders, officials, judges, jurists and other people spoke of him with exceptional respect. The report belongs to the Imamite hadith corpus, but its literary force lies in placing the praise in the mouth of an unfriendly administrative witness rather than only a devoted follower.

The question of succession after him became one of the most consequential issues in Islamic sectarian history. Twelver sources name Narjis as the mother of a son, Muhammad ibn al-Hasan, and commonly place his birth in 255 AH/869 CE. Early reports also show that no heir was publicly obvious when al-Askari died, producing competing groups and claims. Twelver belief identifies Muhammad ibn al-Hasan as the twelfth Imam, the Mahdi, and the Imam in occultation. Sunni hadith traditions contain a broad expectation of a future Mahdi from the Prophet’s family, but they do not universally agree with this specific Twelver historical identification, birth narrative, or doctrine of occultation.

Hasan al-Askari died in Samarra on 8 Rabi I 260 AH/1 January 874 CE according to the widely used chronology; Ibn Khallikan preserves an alternative date of 8 Jumada I/1 March. Shared historical sources establish his death at a young age, while Twelver devotional histories commonly report that he was poisoned through Abbasid instigation, often naming al-Mu'tamid. Because the mechanism of death is not established with equal force across source traditions, the poisoning account must remain explicitly attributed rather than presented as universal fact.

He was buried beside his father in the family house at Samarra. The burial place later became the al-Askari shrine, one of the principal sacred sites associated with the later Imams. The user-supplied GPS coordinates in this file point to the present shrine complex, but a map coordinate is a public location anchor, not by itself proof for every biographical or sectarian claim. The historical burial report rests on written sources; the modern coordinate records the physical site where the graves of Ali al-Hadi and Hasan al-Askari are venerated.
