Kashf al-Yaqin

Kashf al-Yaqin or Kashf al-Yaqin fi Faḍā'il Amīr al-Mu'minīn (Arabic: کشف الیقین) Certainty Uncovered is a medieval Islamic text written by the Shia Islam scholar, Allamah Al-Hilli. Written in Arabic, the book recounts the life and virtues of Ali ibn Abi Talib, the first Imam in Shia Islam and the fourth Caliph in Sunni Islam. It draws upon both Sunni and Shi'a sources to present a theological and historical perspective on Ali's role in early Islamic history.

Commissioned by the Ilkhanid ruler Öljaitü in the 14th century, Kashf al-Yaqin is a notable work in Shi'a literature. The book has been translated into several languages, including Persian and English, with translations by Dr. Ali Akbar Aghili Ashtiani and Sayyed Mojtaba Alavi Tarakamahei.
