Islamic jurisprudence

Islamic jurisprudence, or fiqh, is the human understanding of divine law (sharia). While sharia is considered immutable and revealed, fiqh is the product of juristic interpretation and thus subject to change. It covers all aspects of life, including ritual worship (ibadat), transactions (muamalat), family law, criminal law, and ethics. The term fiqh literally means 'deep understanding' and originally referred to religious knowledge in general, but it came to denote legal science specifically.¹

The primary sources of Islamic jurisprudence are the Quran and the Sunnah (the recorded sayings and actions of the Prophet Muhammad). When these do not provide a clear ruling, jurists use ijma (scholarly consensus) and qiyas (analogical reasoning). The methodology of deriving rulings from these sources is called usul al-fiqh (roots of jurisprudence). It includes principles such as istihsan (juristic preference), istislah (public interest), and ijtihad (independent reasoning). These tools allow jurists to address new situations not explicitly covered by the primary texts.

Islamic jurisprudence began in the 7th century with the companions of the Prophet, who issued legal opinions based on their knowledge. By the 8th and 9th centuries, regional schools emerged in Medina, Kufa, and elsewhere. The four major Sunni schools—Hanafi, Maliki, Shafi'i, and Hanbali—were codified by their eponymous founders and their students. Among Shia Muslims, the Ja'fari school (followed by Twelver Shia) and the Zaydi school are prominent. Each school has its own methodology and rulings, but they all recognize the same fundamental sources.

Beyond the well-known schools, Islamic jurisprudence has a rich tradition of legal maxims (qawa'id fiqhiyya) that summarize principles across areas of law, such as 'certainty is not overruled by doubt' and 'hardship begets facility.' The field also includes siyasa shar'iyya (governance in accordance with sharia), which allows rulers to enact administrative regulations as long as they do not contradict Islamic law. Another niche area is fiqh al-aqalliyyat (jurisprudence for Muslim minorities), which addresses the legal challenges faced by Muslims living in non-Muslim societies. Additionally, the concept of darura (necessity) permits temporary relaxation of certain rules in extreme circumstances, such as allowing the consumption of otherwise forbidden food to save a life.²
