Scholarly Reception and Lasting Influence

Al-Mughni was recognized almost immediately as an authoritative reference not only within the Hanbali school but across all four major madhhabs. Its comparative methodology and rigorous hadith grounding gave it a credibility that transcended sectarian boundaries. Scholars of the Shafi'i, Maliki, and Hanafi traditions cited it when they needed to understand Hanbali positions, when they wanted to access well-organized hadith arguments, or when they were writing works of comparative fiqh.

Within the Hanbali tradition, al-Mughni became the primary reference for difficult legal questions. Subsequent Hanbali scholars — including Ibn Taymiyyah and his student Ibn al-Qayyim — relied on it heavily. Ibn Taymiyyah, who was in many ways a critic of uncritical taqlid (blind following) and sought to re-ground legal conclusions in direct evidence, nonetheless treated al-Mughni as a foundational text because of its systematic engagement with primary sources. This is a significant endorsement: a scholar who insisted on direct textual reasoning found Ibn Qudamah's work methodologically acceptable.

The work's influence on later Hanbali legal writing was comprehensive. Every major Hanbali jurist who came after Ibn Qudamah — including Ibn Muflih, al-Mardawi, and al-Buhuti — built on the foundations laid in al-Mughni. Al-Mardawi's al-Insaf, which surveys internal Hanbali disagreements and identifies the relied-upon positions, cites al-Mughni on virtually every page. This indicates that Ibn Qudamah's positions carried decisive weight in the determination of the official madhab stance.

Beyond formal scholarship, al-Mughni influenced the practice of Islamic courts in the Hanbali regions — particularly in the Arabian Peninsula, where the Hanbali madhab was the dominant legal school. Its rulings provided the framework within which judges operated, and its comparative discussions helped courts understand the options available when the Hanbali position needed clarification or when the parties before the court were from different legal traditions. The influence of al-Mughni in this practical judicial context demonstrates that the work was not merely a monument of scholarly literature but a living tool of governance — a text that shaped real outcomes in real cases across the Hanbali-majority territories. This fusion of scholarly depth and practical applicability is among the highest achievements that any work of legal scholarship can attain.
