Ibn Khallikān says—Jaḥẓah, with a silent ḥāʾ (1)—died in 326 AH. Another report puts his death in 324 AH (2). He had reached the age of eighty. He never engaged in hadith transmission, yet he was a leading authority on astrology and unrivalled at nard (backgammon). He composed a treatise on cookery, and no one exceeded him in the craft of singing (3). He once sang before the caliph al-Muʿtamid, who rewarded him with five hundred dinars. The author of Kitāb al-Aghānī quotes him extensively, as do al-Muʿaffā al-Nahrawānī and Abū ʿUmar ibn Ḥayyawayh (4).

85 – al-Bāb* Abū al-Qāsim Ḥusayn ibn Rūḥ ibn Baḥr

He was the foremost scholar of the Imāmīs and one of the “Gates” to the Awaited Master of the Age: the upright shaykh Abū al-Qāsim Ḥusayn ibn Rūḥ ibn Baḥr al-Qaynī. Ibn Abī Ṭayy states in his History (5) that Abū Jaʿfar Muḥammad ibn ʿUthmān al-ʿUmarī (6) explicitly designated him as his deputy, placing him among the very first to be admitted once he had classified the Shīʿa into ranks.
