And ʿAlī ibn Hārūn ibn ʿAlī is accorded a biographical notice in Ibn Khallikān’s Taʾrīkh(1).

His brother, the distinguished scholar and boon-companion:

194 – Abū Aḥmad Yaḥyā ibn ʿAlī ibn Yaḥyā al-Munajjim*
He served as a convivial attendant to several caliphs, the last of them being al-Muktafī. He composed a number of books and attained high standing. A committed Muʿtazilite innovator, he was a leading figure of that school. Among his writings are al-Bāhir fī Shuʿarāʾ al-Dawlatayn (The Splendid Book on the Poets of the Two Dynasties), later completed by his son Aḥmad ibn Yaḥyā, and al-Ijmāʿ fī al-Fiqh (Consensus in Jurisprudence).

He was one of the foremost pupils of Muḥammad ibn Jarīr [al-Ṭabarī]. Notable incidents and anecdotes are related between him and the Caliph al-Muʿtaḍid. On one occasion al-Muktafī took offense at him and compelled him to go lion-hunting, whereupon he composed verses, including:
‘They have burdened us with hunting beasts of prey, yet we shall fare well—so long as the beasts of prey do not hunt us!’(2)

He lived fifty-nine years and died in Rabīʿ al-Awwal, 300 AH.
