Key Fiqh IssueJihad classification farḍ ʿayn vs. farḍ kifāyahContext-dependent classificationDetermines who must participate and when

School ComparisonAll four schools: defensive jihad is farḍ ʿayn; offensive is farḍ kifāyah when state organizes; minimum one expedition per year (sunnah view by Shāfiʿī); Ḥanbalī: one per year obligatoryFarḍ ʿayn (defensive) / Farḍ kifāyah (offensive)Most significant when Muslim lands are attacked

Uṣūl PrincipleTafāwut al-wujūb graduated obligation based on circumstanceVariable obligation levelObligation level changes with military circumstances

Al-Qurṭubī derives from verse 4 "Allah loves those who fight in His cause in rows as though they were a single compact structure" that organized, disciplined combat is the model of jihad, and that the obligation to participate is calibrated to circumstances. When Muslim lands are attacked (defensive jihad), it becomes farḍ ʿayn on every capable Muslim in the attacked region an individual obligation that cannot be discharged by others. When the Muslim state mounts an expedition into enemy territory (offensive jihad), it is farḍ kifāyah the state bears the duty, discharged when sufficient forces participate.

The Shāfiʿī school's requirement of at least one military expedition per year against non-Muslim territories (as farḍ kifāyah on the state) reflects the classical theory of dār al-Islām expansion. The Ḥanbalī school agrees. The uṣūl principle of tafāwut al-wujūb (graduated obligation) is al-Qurṭubī's framework: the same act (jihad) carries different obligation levels depending on who is attacked, how near the enemy is, and whether the state has mobilized. This prevents jihad from being a continuous farḍ ʿayn on every Muslim at all times.

إِنَّ اللَّهَ يُحِبُّ الَّذِينَ يُقَاتِلُونَ فِي سَبِيلِهِ صَفًّا Inna llāha yuḥibbu lladhīna yuqātilūna fī sabīlihi ṣaffā Meaning: "Indeed Allah loves those who fight in His cause in a row, as though they are a single compact building" Al-Qurṭubī: "ṣaffā" (in a row) organized, unified combat is the legal model; undisciplined fighting or individual freelancing without state organization does not carry the same legal status as organized jihad; state authorization is therefore a condition for offensive jihad.

تُؤْمِنُونَ بِاللَّهِ وَرَسُولِهِ وَتُجَاهِدُونَ فِي سَبِيلِ اللَّهِ بِأَمْوَالِكُمْ وَأَنفُسِكُمْ Tuʾminūna bi-llāhi wa-rasūlihi wa-tujāhidūna fī sabīli llāhi bi-amwālikum wa-anfusikum Meaning: "You believe in Allah and His Messenger and strive in His cause with your wealth and yourselves" Al-Qurṭubī: "amwāl" (wealth) before "anfus" (lives) financial jihad (supporting the war effort) is an obligation parallel to physical participation; those unable to fight physically can discharge the obligation through financial contribution.

Defensive jihad (when Muslim lands are attacked) is farḍ ʿayn an individual obligation on every capable Muslim in the attacked region; cannot be discharged by others.
Offensive jihad (state-organized expedition) is farḍ kifāyah discharged when sufficient forces participate; individual Muslims in other areas are not individually obligated.
State authorization is a legal condition for offensive jihad individual or group expeditions without state sanction do not carry the same legal status.
Financial contribution to the war effort is a parallel jihad obligation "amwāl" before "anfus" in the verse indicates financial jihad is not secondary.
Minimum annual expedition (farḍ kifāyah on the state) per Shāfiʿī and Ḥanbalī the Islamic state bears an annual obligation to maintain the capacity and demonstration of defensive power.
