Abstract

The main framework of this study will take into account the Thanawīya/dualism belief within Islamic sources and the criticism of the Māturīdiya tradition to such doctrines. Firstly, an overview of the Thanawīya belief and its sects have been taken into account with a general perspective from kalām and history of religion works. Thereafter certain early, middle and late period works of the Māturidī tradition regarding the Thanawīya transformation has been analysed throughout the study. Abū Manṣūr al-Māturidīs Kitāb al-Tawhīd and Abū Shakūr al-Sālimīs Tamhīds examples are among such works chosen from the mutaqaddimīn (early) period. In terms of the muteakhkhirīn (late) period which is accepted to be 6/12. Century, works considered to be of the middle period such as Abū-l’Mu‘īn al-Nasafīs Tabṣirat al-‘Adillah and Abū’l-Thanā al-Lāmishīs al-Tamhīd li Qawa‘id al-Tawhīd are also taken into account. Nūr al-Dīn al-Ṣabūnīs al-Kifayah has also been included due to it being an important and influential work. With regards to the latter period, Shams al-Dīn al-Samarqandīs al-Ṣaḥāif al-ilāhiyyah work has been given as an example. Additionally, a brief information from works of the New Science of Kalām era has been mentioned. Upon researching the entire mentioned works regarding the Thanawīya or one of its sects, related sections from these works will be mentioned briefly by comparing with each other. The extent of criticism to the Thanawīya belief in such cases will be analysed.
