'And fight them until there is no fitnah,' meaning: polytheism (shirk). 'Then if they cease,' meaning: from their polytheism, 'then there is no aggression,' meaning: then there is no path (to punish), 'except against the wrongdoers,' meaning: the polytheists.

Muhammad said: The root of aggression is injustice. The meaning of aggression here is recompense; [he says]: there is no recompense [for injustice] except against the wrongdoers. [Verse 194-195]
