"As interest in the Ibāḍiyya continues to grow, the need for reliably edited Ibāḍī sources increases. Following on their earlier publication of the works of the early Omani Ibāḍī jurist, theologian and scholar Abū al-Mundhir Bashīr b. Muḥammad b. Maḥbūb (Early Ibāḍī Literature, Weisbaden, 2011) Drs. al-Salimi and Madelung’s new preparation of al-Fazārī’s kalām texts are a welcome addition to the growing library of early Ibāḍī sources. In addition, such a large collection of early kalām materials illumines in significant ways not only the development of Ibāḍī thought, but the progression of early Islamic theology in general. It is to be hoped that more scholars will follow in the footsteps of the editors, bringing the truly vast and important corpus of Ibāḍī texts to ever wider audiences."Adam R. Gaiser, Florida State University"Der Band – und namentlich die Typographie des arabischen Teils – sind sehr ansprechend gestaltet".Jan Thiele in Wiener Zeitschrift für die Kunde des Morgenlandes, vol. 106/2016
