Foundations of Jurisprudence: An Introduction to Im m Sh Legal Theory is a critical edition of Mab di al-wu l il ilm al-u l by al- All mah al- ill, based upon six manuscripts, four of which date from the lifetime of the author. Sayyid Amjad H. Shah Naqavi has provided a critical edition of the Arabic text, along with an English translation, and analytical introduction. Al- All mah al- ill participated in leading debates of his day and applied his vast erudition in philosophy, logic, and theology to the paramount subject of jurisprudence. This text presents an exemplar of the rich revival of Sh scholarship in the thirteenth and fourteenth centuries CE. Concise, yet comprehensive, this work sets the standard for the subsequent development and discussion of Im m Sh legal theory, such that its influence can be traced through to modern times. This dual-text edition is indispensible for students and scholars of Im mi Sh jurisprudence."
