An extensive work by one of the late, great scholars of Islam, Shaykh al-Saduq. It covers the topic of khalifat (successorship) starting from Prophet Adam (peace be upon him) to the last savior known as the Mahdi (may his return be hastened). It covers the leadership of the main prophets of Islam as well--a must read for Muslims and non-Muslims alike!
The book deals with the personality of the Hidden Imam, his occultation and everything related to him with analytical and systematic manner and is penetrating in its subject and exceptional in its domain. Ahadith have been quoted extensively from the Holy Prophet sawa and the Infallible Imams in support of the writer's contentions. The book is in two volumes and carries original Arabic text on one side of the page and its English translation on the opposite side.
