Tahdhib al-ahkam (book)
|Original title||تَهذیب الأحکام|
Tahdhīb al-aḥkām (Arabic: تَهذیب الأحکام) is a collection of hadiths by Abu Ja'far Muhammad b. Hasan al-Tusi (d. 460/ 1068) known as Shaykh al-Ta'ifa and al-Shaykh al-Tusi. For Imamiyya, this is one of the most reliable collections of hadiths and one of al-Kutub al-Arba'a (the Four Books). Al-Shaykh al-Tusi authored the book before writing his al-Istibsar. Tahdhib al-ahkam includes only hadiths related to the laws of sharia.
