The Four Rules of God (Mauretanian: Arbá Égras al'Alá) are a set of guidelines for religious tolerance created by the Empire of Mauretania and enforced through its domains. Historically, a religious sect could only be tolerated by the Imperial Government if it accepted these Four Rules: * No aggressivity against any other religion; * No aggressive recruitment or proselytism; * No aggression against the moral rules of the majority of belivers from all the religions; * No incitation to civil disorder.
