The accumulation of Ottoman exegesis has not been enlightened yet. However, with recent scientific studies, this closedness has been tried to be partially eliminated, but these efforts have not been achieved to the desired level. In this study, we will focus on the work of "Fusul al-Taysir fi Usul al-Tafsir", an unknown commentary of Isma`il Haqqi's (1846-1912), one of the last Ottoman scholars. This work, which we will focus on, was prepared by Isma`il Haqqi for the first grade students of the Faculty of Political Sciences as a textbook. In this study, in the context of the exegesis works of the Ottoman period, this work which can be evaluated in the works written about the exegesis method independently; systematics, contents and sources. On this occasion, the contribution of a recent Ottoman scholar to the tradition of exegesis will be discussed and, albeit a bit, the course of Ottoman exegesis will be shed light.
