Q: Salamalikum, What is the islamic idea on aggression? Can one be aggressive to a person if they are not part of the faith? Can one be aggressive to family because of a past problem?
Islam teaches that aggression and violence are not acceptable behaviors, except in cases of self-defense or in the defense of others. Allah (SWT) states in the Quran: There is no aggression except against the oppressors (2:193). This can only be carried by a legal and approved court system. Aggression and violence should only be used as a last resort, when all other efforts to address a problem or conflict have failed and there is no other way to protect oneself or others from harm.
Islam also teaches Muslims that all human beings have inherent dignity and value, it is central to Islam to treat others with kindness, compassion, and respect — be the part of the Islamic faith, or not. The Quran states that Allah does not love the aggressors (2:190) and that believers should repel evil with that which is better (41:34). This means that when faced with aggression or violence, Muslims are encouraged to respond with calmness, patience, and forgiveness, rather than with more aggression or violence.
Allah Certainly knows Best.
