A Manual of Zaydī Muʿtazilī Dogmatic Texts from Early Sixth/Twelfth-Century Iran

MS Riyadh, Maktabat Malik Fahd al-Waṭaniyya 748 is a multitext volume copied by al-Ḥasan b. Muḥammad b. Aḥmad b. ʿAlī Ibn Abī l-ʿAshīra in 552/1157 in Ṣaʿda. It consists of doctrinal texts by Zaydī and Muʿtazilī authors, invariably Iranian. The codex is the only known extant witness of all but two of the tracts it includes (the exceptions being Ismāʿīl b. ʿAlī b. Ismāʿīl al-Farrazādhī’s K. Taʿlīq al-Tabṣira and Abū ʿAbd Allāh Muḥammad b. al-Ḥasan al-Dāʿī al-Ḥasanī’s K. Ḥaqāʾiq al-aʿrāḍ wa-aḥwālihā wa-sharḥihā), and two of its tracts, K. al-Nasīm fī l-uṣūl by one Abū Jaʿfar and K. Muhaj al-ʿulūm by Muʿādh b. Abī l-Khayr al-Hamadhānī, are not even attested in the relevant biobibliographical sources. This study includes critical editions of the doctrinal tracts included in the majmūʿa as well as an additional tract preserved in a related codex that was apparently also copied by Ibn Abī l-ʿAshīra (MS Milan, Ambrosiana, ar. E 462). The edited tracts include Abū l-Faḍl al-ʿAbbās Ibn Sharwīn’s K. al-Wujūh allatī taʿẓumu ʿalayhā l-ṭāʿāt ʿinda llāh, his K. al-Yāqūta, and his Ḥaqāʾiq al-ashyāʾ, ʿAbd al-Jabbār al-Hamadhānī’s Ḥudūd al-alfāẓ, Ibn al-Dāʿī’s K. Ḥaqāʾiq al-aʿrāḍ wa-aḥwālihā wa-sharḥihā, the extant part of the K. al-Nasīm fī l-uṣūl, K. Muhaj al-ʿulūm, by Muʿādh b. Abī l-Khayr al-Hamadhānī, fragments of two theological summae by unidentified Zaydī scholars, and collections of doctrinal definitions of uncertain authorship.
