This paper was delivered at the Congress of the American Oriental Society in Santa Barbara in March 1974. In it, Wilferd Madelung presents his exhaustive research into the origins and sources of a monumental document that was considered lost to history; the Kitab al-idah, Qadi al-Nu‘man’s first legal work – a vast collection of legal traditions transmitted from the family of the Prophet (ahl al-bayt), indicating their points of consensus (ijma‘) and conflict (ikhtilaf) and elucidating what was firmly established doctrine in them with evidence and proofs. This article provides an invaluable resource for academics and students of Islamic studies and related fields.
