The phrase refers to a modern rhetorical and ideological stance within Islamic discourse, often expressed through nasheeds (Islamic vocal chants) that denounce extremist groups by comparing them to the historical Khawarij . In contemporary contexts, particularly in conflicts between rival militant groups or in anti-extremism propaganda, the label "Khawarij" is used as a powerful pejorative to delegitimize organizations like ISIS by framing them as renegades who have "exited" the true path of Islam. The Identity of the Khawarij

The "Storm the Khawarij" nasheed sits in a legal grey area. It is not simply a "song" but incitement to terrorism under UN Security Council Resolution 1624 (2005) and national laws in the UK (Terrorism Act 2006), the USA (18 U.S.C. § 2339B), and Europe.
