While al-Isfahani's Baghdadi informants were wide-ranging in their expertise as well as sectarian and theological tendencies, his Kūfan sources, to a certain degree, can be characterised as either Shi'i or keen on preserving and disseminating memory that favours Ali and his family. For example, Ibn ʿUqda (d. 333/944), mentioned in both the Aghānī and the Maqātil, is invariably cited for the reports about the Alids and their merits.[83][84][85][lower-alpha 22]
