Aggression is mentioned in the Quran in these verses:
[7:33] Say, “My Lord prohibits only evil deeds, be they obvious or hidden, and sins, and unjustifiable aggression, and to set up beside God powerless idols, and to say about God what you do not know.”
[8:39] You shall fight them to ward off oppression, and to practice your religion devoted to God alone. If they refrain from aggression, then God is fully Seer of everything they do.
