Muʿtazilite exegetical tradition has been defined primarily by reference to the theological dimensions of the tafsīr works authored by the Muʿtazila. This article is an attempt to go beyond this focus by exploring the significance of an exegete's affiliation to the tradition that is implicit in his selection of interpretations and his references to authorities. Focusing on the tafsīr of the tenth-century Muʿtazilite scholar ʿAlī ibn ʿĪsā al-Rummānī, the article analyses al-Rummānī's references to his three Muʿtazilite predecessors: Abū ʿAlī al-Jubbāʾī, Abū l-Qāsim al-Balkhī and Ibn al-Ikhshīd. The content of these references indicates that, for al-Rummānī, the authority of these Muʿtazilite scholars extended beyond their views on the theological implications of the Quranic verses. The context suggests that the scholars were part of a distinct exegetical tradition that allowed for certain differences of opinion.
