Fiqh al-Jihad (فِقهُ الجِهَادِ — Jurisprudence of Struggle; *jihad* — striving, exertion; the legal framework governing Islamic warfare, including its justification, initiation, conduct, cessation, and the treatment of enemy combatants, civilians, property, and prisoners) is one of the most developed areas of classical Islamic law — elaborated by jurists of all four schools, systematized by scholars like al-Awzai, al-Shaybani, and later Ibn Rushd. The framework is simultaneously a law of war and a framework of ethical constraint: Islamic armies historically operated under rules governing who may be targeted, what may be destroyed, how prisoners must be treated, and when peace must be accepted.

The Classic Non-Combatant Protections

From the Prophet’s instructions and the early Caliphs’ commands before battles:

These are reported as direct prophetic commands and were transmitted as operational orders to Muslim armies.


The Proportionality Principle

The Quran (2:194): “Transgression shall be requited by transgression equivalent. But whoever pardons and makes peace — his reward is with God.” The principle: response to aggression must be proportionate, and forgiveness is actively preferred.

The classical jurists required that jihad be:

  1. Declared by legitimate authority — not by individuals or non-state actors
  2. Preceded by invitation (da’wa) — giving the opposing side the option of peace
  3. Limited to combatants — civilian protection is not optional
  4. Proportionate — the destruction inflicted must not exceed what the military objective requires

Al-Awzai’s Contribution

Al-Awzai of Syria (d. 774 CE) is credited by some historians with the first systematic Islamic law of war treatise — a genre that predates the European development of similar frameworks by over seven centuries. His correspondence with Abu Yusuf (al-Hanafi) over the legal treatment of enemy property and prisoners established precedents still cited.


Prisoners of War

The Quran (47:4): “Thereafter either be gracious or accept ransom.” For prisoners: after battle they could be freed freely, ransomed, exchanged for Muslim prisoners, or (in the framework of the time) enslaved. The Prophet’s practice after Badr — ransoming literate prisoners in exchange for teaching Muslims to read — became a precedent for non-material forms of release.
