An Original Examination of the Doctrine of Necessity (Darura) in Islamic Law and Its Contemporary Application to Nigerian Public Law Challenges

The Islamic doctrine of Darura (necessity) permits departure from ordinary legal rules when compelling circumstances create a state of necessity, and its application has been invoked across classical Fiqh in questions ranging from emergency medical treatment to emergency political authority. In contemporary Nigerian Islamic law, Darura has been invoked in judicial decisions, Fatwa opinions, and legislative debates to justify exceptional measures in public law contexts including pandemic governance, emergency security measures, and exceptional financial practices. This study develops an original examination of the theoretical structure of the Darura doctrine and its application to contemporary Nigerian public law challenges. A theoretical and empirical doctrinal methodology is applied, constructing a comprehensive typology of Darura doctrine from classical sources (Ibn Nujaym, Al-Suyuti, Al-Zarkashi) and then systematically analysing its invocation in forty northern Nigerian judicial decisions and twenty-five published Fatawa from 2014 to 2023. The theoretical contribution identifies four previously unrecognised sub-categories of Darura reasoning (temporal, institutional, structural, and individual necessity) that characterise different invocation patterns in the Nigerian judicial record. The study further develops original criteria for distinguishing legitimate Darura invocation from its abuse as a blanket justification for circumventing Islamic rights protections. Available Islamic legal theory literature from Nigeria identifies the under-theorised character of Darura in Nigerian judicial reasoning as a significant doctrinal gap.
