The term Salafist Group is often used to refer to militant Islamic organizations that follow a strict interpretation of Islam based on the practices of the first three generations of Muslims following the Prophet Muhammad. However, there are several synonyms for Salafist Group, including Salafi Jihadist, Salafi-Sunni, Wahhabi, and Takfiri. Salafi Jihadist emphasizes the use of violence to achieve their goals, while Salafi-Sunni refers to strict adherence to Sunni Islam as practiced during the time of the Prophet and his companions. Wahhabi is a term used to describe followers of an 18th-century Islamic reform movement in Saudi Arabia, while Takfiri denotes those who declare other Muslims as infidels and enemies. Ultimately, all these terms refer to Islamic groups that pursue strict and often violent interpretations of Islam.
