Kamāl al-Dīn wa Tamām al-Niʿma - The Perfection of the Religion

Kamāl al-Dīn wa Tamām al-Niʿma (The Perfection of Religion and the End of Divine Favor), compiled by the great Shīʿī scholar al-Shaykh al-Ṣadūq (d. 381 AH/991 CE), is a seminal theological and historical work written during the formative period following the Major Occultation (al-Ghayba al-Kubrā) of the Twelfth Imam, Muhammad al-Mahdi (a). Its primary subject is a systematic and comprehensive defense of the doctrine of occultation and the imamate of the Hidden Imam, making it the oldest and most authoritative Ḥadīth reference on this central tenet of Twelver Shīʿī belief.
