Aydınlı Rûşeni Ömer Dede'nin Kadı Beyzâvî tefsirine hâşiyesi ankebut sûresinin başından fâtır sûresinin sonuna kadar (inceleme ve tahkik)

The aim of this thesis is to examine and verify the valuable scientific annotation made by Dede Omar Rushani Aydini (d. 892/1487), one of the scholars of the Ottoman period, to the Bydawi Tafsir, from the Ankabut Sura to the end of the Fatır Sura. Aydini's annotation includes the views of the commentators in the interpretation of the verses, the reasons for the revelation of the verses, and the solutions to the problems and objections that arise in some verses. In addition, the views of linguistic, grammatical and grammatical scholars in order to explain the words and determine their origins and places are also included. The work touches upon the science of meaning, the effect of context, the characteristics of meaning and the elements of rhetoric such as priority-recency, determination-ambiguity. The researcher used the descriptive historical method while examining the author's personal and scientific life, and the scientific examination method in the verification of the manuscripts. Thanks to this study, light has been shed on Aydini's life, it has been proven that the annotation belongs to the author, his method in the exegesis has been clarified, and his different sources and rich knowledge have been revealed. He has generally supported the exegetical views he included in the work with logical evidence; he has resorted to verses and hadiths to prove the accuracy of his views and, when he deemed appropriate, he has consulted the views of lexicographers, linguists and rhetoricians. He has paid particular attention to linguistic exegesis by using simple and understandable language. His critical personality has come to the fore in the annotation; he has supported his unique views with logical justifications, and he has dealt with linguistic issues including grammar, grammar, eloquence, exegesis, jurisprudence, hadith, and even various branches of science such as logic and theology .
