Overview
Defense Is Permitted, Aggression Is Not
This framework protects two truths at once. Victims are not required to accept destruction while calling it spirituality, and anger does not free them from moral responsibility. Islam recognizes that force can sometimes stop a greater injustice, but it refuses to worship force or to treat vengeance as justice.
scripture
Why the First Muslims Were Permitted to Fight
The first Muslims had endured years of abuse before receiving permission to fight. This history matters because it shows the difference between patience during vulnerability and passivity when a community can lawfully protect the persecuted. Surah al-Nisa (4:75) also challenges believers about failing to defend oppressed men, women, and children who cry for rescue. Defense in Islam includes concern for people who cannot defend themselves.
scripture
The Limits Are Part of the Permission
Justice also forbids collective guilt. The wrongdoing of a government, army, or faction does not make every person who shares its nationality responsible. Surah al-An'am (6:164) states that no bearer of burdens bears another's burden. In war, as in ordinary judgment, responsibility attaches to conduct. This is why reprisals against families and attacks designed to frighten a population are incompatible with Islamic ethics.

وَقَٰتِلُوا۟ فِى سَبِيلِ ٱللَّهِ ٱلَّذِينَ يُقَٰتِلُونَكُمْ وَلَا تَعْتَدُوٓا۟ ۚ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْمُعْتَدِينَ
سورة البقرة · الآية ١٩٠
Fight in the way of Allah those who fight you but do not transgress. Indeed. Allah does not like transgressors.

The Prophet Protected Noncombatants
Treaties in the Prophet's life show that peace was a real legal relationship, not a pause used only for tactical betrayal. The Treaty of Hudaybiyyah included terms many companions found difficult, yet the Prophet honored it. When conflict resumed, it was linked to a breach by the opposing alliance. Muslims presenting this history should emphasize the religious weight of keeping one's word.

Self-Defense in the Biblical Tradition
The New Testament's personal ethic of nonretaliation can inspire remarkable forgiveness. Christian just-war thinkers nevertheless distinguished private revenge from the public duty to protect society. Islam makes a similar distinction in its own sources: a person may forgive an injury to himself, while a government may still be responsible for stopping an aggressor and protecting others. Mercy and public justice are related but not identical duties.
Key passage
Bible
When those who were around him saw what was about to happen, they said to him, “Lord, shall we strike with the sword?” A certain one of them struck the servant of the high priest, and cut off his right ear. But Jesus answered, “Let me at least do this”—and he touched his ear, and healed him.
Luke 22:49-51
Version: World English Bible
summary
Strength Governed by God-Consciousness
Applied personally, self-defense should use no more force than needed to escape danger. Applied publicly, it requires legitimate authority, reliable evidence, distinction between fighters and civilians, and willingness to stop. The same believer who asks Allah for help must fear standing before Him with innocent blood.
