There are many rulings in Islamic law that are not duties meant to be fulfilled by the individual; instead, they are the domain of the political authority or its representative. Among such rulings are military actions and the moral duty to enjoin good and forbid evil. Forbidding evil can sometimes have uncertain consequences, requiring serious deliberation that cannot be done by just anyone. Sometimes it can lead to an even greater evil, and in such a case, forbidding evil would be prohibited for individuals. The same applies to military action such that the government is the only one ordained to attack enemy states abroad, assemble troops, or suppress insurrection. This is mentioned in al-Qarafi’s Distinctions, where he discusses the engagement by the government; he notes that individuals cannot take on such engagement and that it must be carried out by the government only. The wisdom behind this is that some of these groups that we see today working to redress wrongs by force actually cause civil strife and widespread corruption.
