al-Usul min Ilm al-Usul

al-Usul min Ilm al-Usul (The Foundations of the Science of Legal Theory) is a concise introductory treatise on Islamic jurisprudence and legal theory (usul al-fiqh) composed by the Saudi Hanbali scholar Muhammad ibn Salih al-Uthaymin (1347–1421 AH / 1929–2001 CE) al-Usul min Ilm al-Usul+1.

Background and Purpose

Ibn Uthaymin authored the treatise as a targeted educational text following the curriculum designated for the third secondary year in Saudi religious institutes (al-Ma'ahid al-Ilmiyyah) al-Usul min Ilm al-Usul. The manual was designed to provide students with a foundational grounding in the core terminology, principles, and analytical instruments of legal theory al-Sharh al-Kabir li-Mukh…+1.

Content and Structure

The treatise begins by outlining foundational concepts, defining usul al-fiqh both as a genitive compound (murakkab idafi) and as an established technical title (laqab) for the independent discipline, along with defining its utility: acquiring the capacity to derive practical legal rulings from their overarching proofs on sound foundations al-Usul min Ilm al-Usul+1. It notes that Muhammad ibn Idris al-Shafi'i was the first to compile legal theory as an autonomous science al-Usul min Ilm al-Usul.

The book is structured around standard divisions of legal theoretical discourse:

• Legal Rulings (al-Ahkam): Definitions of divine legislation, dividing rulings into prescriptive norms (al-ahkam al-taklifiyyah)—the obligatory (al-wajib), recommended (al-mandub), prohibited (al-muharram), disliked (al-makruh), and permissible (al-mubah)—and declaratory norms (al-ahkam al-wad'iyyah), including legal validity (al-sihhah) and invalidity (al-fasad) in both acts of worship and contracts al-Usul min Ilm al-Usul+3.
• Linguistic and Textual Evidences: The classification of speech, textual commands (al-amr) and prohibitions (al-nahy), general and specific expressions (al-amm wa-l-khass), absolute and qualified language (al-mutlaq wa-l-muqayyad), and clarification (al-mujmal wa-l-mubayyan) al-Usul min Ilm al-Usul+1.
• Legal Epistemology and Proofs: Discussions on abrogation (al-naskh), transmitted reports (al-akhbar), scholarly consensus (al-ijma'), and analogical deduction (al-qiyas) al-Usul min Ilm al-Usul.
• Hermeneutics and Ijtihad: Resolution of apparent textual contradiction (al-ta'arud), juristic reasoning (ijtihad) alongside its strict prerequisites, following qualified authority (taqlid), and the norms governing legal responses (al-ifta') al-Usul min Ilm al-Usul+1.
