He died in Shaʿbān of the year 454 AH (1) after contracting leprosy. His poet, al-Ḥasan ibn Rashīq of Qayrawān (2), composed an elegy for him, and his death took place at al-Mahdiyya (3). After him the authority passed to his son Tamīm (4) ibn al-Muʿizz.

76 – al-Jaʿfarī, Abū Yaʿlā Ḥamzah ibn Muḥammad al-Hāshimī
A scholar of the Imāmī school, the noble Abū Yaʿlā Ḥamzah ibn Muḥammad al-Hāshimī, known as al-Jaʿfarī, was one of the leading advocates of Shīʿism. He closely accompanied Shaykh al-Mufīd (5), achieving mastery in their jurisprudence, legal theory, and dialectical theology; al-Mufīd married him to his daughter and entrusted him with his books. He also studied under al-Sharīf al-Murtaḍā, authored several works, and used to argue for the Qurʾān’s originated nature on the basis that it contains both abrogating and abrogated material. He was moreover skilled in Qurʾānic readings. Ibn Abī Ṭayy says in his History of the Shīʿa: “He was among the righteous of his sect.”
