Usul al-Fiqh
Usul al-Fiqh (أصول الفقه) is the methodological discipline that governs the interpretation of textual sources and the derivation of legal rulings in Islam. It establishes how the Qur’an, Sunnah, Ijma, and Qiyas are interpreted, prioritized, and synthesized. While Fiqh is the product, usul is the process.
It is not a theological discipline, but an epistemological one, concerned with the tools, categories, hierarchies, and limitations of ijtihad.
