against the other and refuses to respond to the judgment of Allah’s Book, then fight the one that transgresses until it returns—that is, goes back—“to Allah’s command,” as set forth in His Book. “But if it returns,” that is, returns to the truth, “then make peace between them with justice,” by requiring both parties to be fair and to accept Allah’s judgment. “And be equitable,” that is, act justly. “Surely Allah loves those who uphold justice.”
“Indeed, the believers are brothers, so reconcile your two brothers, and fear Allah, so that you may receive mercy.” (10)
“Indeed, the believers are brothers” in religion and mutual allegiance. “So reconcile your two brothers” when they differ and fight one another.
