Al-Istibsar

Al-Istibsar is one of the four major books of hadith in Shia Islam, compiled by Shaykh al-Tusi (d. 460 AH). It is a collection of narrations focused primarily on jurisprudence, serving as a key source for deriving Islamic legal rulings. The book is unique in its structure: it presents hadith alongside potentially conflicting narrations, followed by explanations that reconcile the differences. That method makes it an essential reference for anyone seeking to understand and resolve variations in Islamic legal traditions, arranged for ease of study across acts of worship, transactions and personal status law.
