Abstract
The first sect that emerged in the history of Islam was the Khārijite. The Khārijites were divided into different subgroups at the time, and only the Ibādītya sect of has continued to the present day. Shortly after they were formed as a group, the Khārijites quarreled among themselves and decoupled into different groups. One of the reasons for this debate is related to the attitude they will show to their opponents. Some of them have been extremely strict and thrifty towards their opponents. Some of them have taken a softer and more understanding attitude. Those who were relentless with their opponents have been erased from history. The non-marginal ones have continued their existence to the present day. Representing the moderate wing of the Khārijites, the Ibādīte have continued their existence until today. Although the Ibādīte remains a minority sect in the shadow of Khārijite throughout history, Ibādītes have succeeded in creating their own religious and intellectual literature. In the historical process, almost all of the literature that has survived in the context of Khārijite- Ibādīte belongs to the Ibādītes. There is an academic interest in Ibādīte in our country, especially recently. One of the most critical issues in the study of literature is terminology. Because words acquire different meanings when they enter thought systems, it is possible to understand literature correctly only by knowing its terminology. In this context, the Ibādītes has created a particular vocabulary for themselves. This research aimed to identify and define the concepts frequently used in the Ibādīte literature. The research subject is the concepts used by the authors of the sect with meanings unique to the Ibādīte. Therefore, the study did not aim to identify all the concepts belonging to the Ibādīte. Particular attention was paid to identifying concepts with specific uses and contents of Ibādītes. The concepts identified are given in alphabetical order. This article has been prepared using screening and comparison methods. For the meanings of the terms, primarily Ibādīte sources and dictionaries were used, and comparisons were made by referring to non-sectarian works where necessary. This study generally consists of two parts. In the introduction and the first part of the study, brief information about the concept of Ibādīte and terminology is given; In the second part, the identified concepts were divided into three groups and presented as items.
