The Methodology of Comparative Fiqh in Al-Qawanin

Al-Qawanin al-Fiqhiyyah's comparative approach represents an important but underappreciated strand of Islamic legal scholarship. While the dominant tradition was school-internal — scholars presenting and defending their own school's positions — a comparative tradition also existed, aimed at understanding legal diversity rather than resolving it. Ibn Juzayy's work is one of the finest examples of this comparative tradition in the Maliki school.

The purpose of the comparative approach in al-Qawanin is not to identify the 'correct' position across all schools or to adjudicate between them. Ibn Juzayy is a committed Maliki scholar presenting the Maliki positions as primary. The comparative notes serve a different function: they contextualize the Maliki positions within the broader landscape of Islamic legal reasoning, show students where the Maliki school stands relative to the other schools, and prepare them for engagement with the full range of Islamic scholarly opinion.

This preparation was practically important in the cosmopolitan context of medieval Andalus, where scholars and judges encountered Muslims of different school affiliations regularly. A Maliki judge who understood the Shafi'i or Hanafi positions could engage more productively with litigants who followed those schools, and could make better-informed decisions about when to apply strict school doctrine and when to consider the weight of the broader Islamic scholarly consensus.

Ibn Juzayy's approach also reflects a theological principle that Islamic scholars had long maintained: the differences between the four recognized legal schools are legitimate expressions of diversity within the unified framework of Islamic law, not evidence that some schools have departed from the truth. By presenting the positions of all four schools respectfully and without disparagement, al-Qawanin embodies the principle of rahmat al-ikhtilaf — the mercy inherent in the diversity of scholarly opinion — that many classical scholars articulated.

The legacy of al-Qawanin al-Fiqhiyyah in the Maliki world is that of a reliable comparative reference that combines Maliki fiqh with inter-school awareness. Students who master it understand not only what their school holds but why, and how their school's positions relate to those of other legitimate Islamic legal traditions. This breadth of perspective is increasingly valued in contemporary Islamic scholarship, where inter-school dialogue and understanding are seen as essential for navigating the global diversity of Muslim legal practice.

For historians of Islamic law, al-Qawanin al-Fiqhiyyah is a valuable document of Andalusian Islamic scholarship at its most sophisticated — a tradition that combined rigorous school-based training with an openness to comparative legal reasoning that made it uniquely equipped to engage with the intellectual challenges of a diverse and complex civilization.
