His insistence on the limits of law underscores the importance of non-legal (not to be confused with illegal) considerations in determining the proper course of action, with significant implications for legal reform in the modern Islamic world. His views on the common good (maslahah) and custom provide means to accommodate the space-time differential between modern and premodern realities. The most important of his many works are Al-dhakhirah (The Stored Treasure), Al-furuq (Differences), Nafais al usul (Gems of Legal Theory), and Kitab al-ihkam fi tamyiz al-fatawa an al-ahkam wa tasarrufat al-qadi wal-imam (The Book of Perfecting the Distinction Between Legal Opinions, Judicial Decisions, and the Discretionary Actions of the Judge and the Caliph).
