The proposed paper deals with Abū ʿAbd Allāh Muḥammad b. ʿAlī b. ʿUmar al-Māzarī (d. 536/1141), a Tunisian scholar of Sicilian descent known to have been well-versed in a large number of disciplines such as ḥadīth, Ašʿarī theology, Mālikī jurisprudence, legal theory, arithmetic, adab literature, and medicine. Although he was apparently a prolific scholar, only few of his works (and a number of scattered fatwās) have come down to us, and unfortunately the theological tract entitled al-Fawāʾid fī ʿilm al-ʿaqāʾid is not one of them. To a large extent, however, his theological outlook can be deduced from the work for which he is best known: a commentary on Ṣaḥīḥ Muslim entitled al-Muʿlim bi-fawāʾid Muslim, which is based on lecture notes taken by al-Māzarī's students. It is available in a three-volume edition by Muḥammad al-Šāḏilī al-Nayfar (Tunis: Dār al-Ġarb al-Islāmī, 1988). I have selected four short chapters from al-Muʿlim for discussion, namely Kitāb al-ruʾyā, Kitāb al-qadar, Kitāb ṣifat al-qiyāma wa-l-ǧanna wa-l-nār and Kitāb al-ǧanna wa-l-nār, which together give a good indication of his views.
