Sayyid Muḥammad Abū Jaʿfar was the eldest son of ʿAlī al-Hādī and older brother of al-Ḥasan al-ʿAskarī. He is widely known by the title Sabʿ al-Dujayil — the Lion of Dujayil — in reference to the ancient Dujayil river, a tributary of the Tigris, that once flowed through the region where he died and was buried. He was born around 228 AH in the village of Ṣurayā near Medina — the same village founded by Mūsā al-Kāẓim — and left there as a child when his father was summoned under duress by the Abbasid caliph al-Mutawakkil to Samarra. He grew up in Medina, known for his gravity, piety, and exceptional character. A contemporary named ʿAllān al-Kalābī who knew him in his youth said he had never seen anyone more dignified, more pure, or more noble in bearing. Many believed he would be designated to follow his father in spiritual leadership, given his seniority and manifest qualities. In 252 AH he made the Hajj and then travelled to Samarra to visit his father. On his return journey toward the Hijaz, he fell suddenly and gravely ill in the town of Balad — approximately nine farsakhs from Samarra — and died there on the 28th or 29th of Jumādā al-Ākhira 252 AH, aged around his mid-twenties. The cause of his death remains uncertain in the sources; a number of scholars consider it likely he was poisoned by Abbasid agents, who knew of his standing among the community and feared him as an heir apparent to his father's authority. He was buried where he died, and the site became a place of visitation and deep veneration. The shrine's earliest construction is attributed to the Buyid ruler ʿAḍud al-Dawla al-Daylamī in the fourth Islamic century, and it was later rebuilt by the Safavid Sultan Ismāʿīl after the conquest of Baghdad. The mausoleum has a dome, a courtyard, and surrounding rooms, and draws pilgrims who hold the Sayyid in the highest esteem — a reverence that has endured across centuries and communities throughout the region.
