For known specification, the source uses a classical legal illustration involving the general term mushrikin and an exclusion for ahl al-dhimmah, people protected by covenant in the historical Islamic legal setting.
The point is the formal structure of specification: a general class, an identifiable excluded group, and a remaining class. The illustration is not a present-day instruction authorizing individuals to act violently. Questions of safety, legal authority and historical conditions require their own governing rules.
