Analytical Study of the Compatibility of Islamic Human Rights Doctrine with the Nigerian Constitutional Rights Framework

The relationship between Islamic human rights concepts, as articulated in instruments like the Cairo Declaration on Human Rights in Islam, and the internationally influenced rights framework of the 1999 Nigerian Constitution is a theoretically contested terrain with practical implications for the operation of Sharia law in multi-constitutional Nigeria. This study analytically examines the areas of compatibility, tension, and irresolvable conflict between Islamic human rights doctrine and the Nigerian constitutional rights framework. A comparative doctrinal methodology is applied, systematically comparing the provisions of the Cairo Declaration 1990, classical Islamic jurisprudence on political and personal freedoms, and the Chapter IV rights provisions of the 1999 Nigerian Constitution across eleven identified rights categories including freedom of religion, right to life, gender equality, freedom of expression, and fair trial. The analysis draws on comparative constitutional jurisprudence from the Nigerian Supreme Court and the African Court of Human and Peoples' Rights alongside Islamic law scholarship. Available comparative law literature identifies significant compatibility in fair trial, right to life, and family privacy provisions while identifying material tensions in religious freedom, gender equality, and freedom of expression rights. The Maqasid al-Shariah hierarchy and the African Charter on Human and Peoples' Rights provide additional comparative frameworks. Findings are expected to map both convergence and divergence across rights categories with nuanced doctrinal analysis. Recommendations address legislative drafting approaches that honour both frameworks in areas of tension.
