Introduction

Muhammad al-Tahir ibn Ashur (1879–1973 CE / 1296–1393 AH) was among the most eminent Maliki scholars of the twentieth century, serving as the Grand Mufti and Shaykh al-Islam of Tunisia and as the rector of the Zaytuna mosque-university. His Maqasid al-Shariah al-Islamiyyah, first published in 1946, represents the first full-length systematic treatise devoted entirely to the theory of the higher objectives of Islamic law. While the concept of maqasid had been discussed by earlier scholars — most notably by al-Ghazali in Al-Mustasfa, al-Izz ibn Abd al-Salam in Qawa'id al-Ahkam, and al-Shatibi in Al-Muwafaqat — Ibn Ashur elevated maqasid from a supporting tool of legal methodology into an independent discipline with its own principles, definitions, and investigative framework.

The significance of this work lies in the intellectual problem it addresses: how can Islamic jurisprudence remain coherent, adaptive, and authoritative in a rapidly changing modern world without sacrificing its fidelity to divine revelation? Ibn Ashur's answer is that the fuqaha must engage systematically with the purposes behind the rulings of the Shariah, not merely with the rulings themselves. He argues that the Shariah has demonstrable higher objectives — among them the preservation of religion, life, intellect, lineage, and wealth — and that understanding these objectives allows jurists to reason about novel situations with principled consistency. His framework strengthens legal reasoning by anchoring it to the overarching wisdom of divine legislation rather than leaving it to the vagaries of analogical reasoning alone.

Ibn Ashur's methodology is both inductive and normative. He examines the totality of Islamic legal rulings across the four accepted madhabs to extract recurring patterns that reveal the underlying objectives of the Shariah, then formulates these objectives as positive principles that can guide new legal determinations. He insists that maqasid must be derived rigorously from the primary sources — Quran, Sunnah, and scholarly consensus — and warns against the misuse of maqasid-reasoning as a pretext to override clear textual rulings. This careful balance between methodological innovation and textual fidelity is what has made the work authoritative across a wide spectrum of Sunni scholarship.

For students of Islamic law and legal theory, Maqasid al-Shariah al-Islamiyyah is essential reading. It provides not only a theoretical framework but a practical methodology for jurisprudential reasoning in contemporary contexts — from bioethics to financial regulation to governance. Scholars working in Islamic economics, family law, human rights discourse, and environmental jurisprudence have drawn heavily on Ibn Ashur's framework. Readers should approach the work systematically, engaging first with his foundational definitions before moving to his applied analysis, and should read it alongside Al-Shatibi's Al-Muwafaqat to appreciate how Ibn Ashur built upon and extended the classical tradition.
