David Vishanoff's thorough and original unpacking of the Sunn¿ jurist al-Juwayn¿'s (1028-1085) Kit¿b al-Waraq¿t f¿ ü¿l al-fiqh introduces English-speaking readers to the main concepts, terms, principles, and functions of the classical Islamic discipline of legal theory. This volume offers an ideal entry to the otherwise dense and complex mainstream Sunn¿ views that dominated Islamic legal thought in al-Juwayn¿'s day-and that are still widely accepted today. A critical edition of al-Juwayn¿'s Arabic text is also included.
