Haqqul Yaqeen, A Compendium of Twelver Shia Religious Beliefs

The book in our hand is a masterpiece of Allamah Muhammad Baqir Majlisi (r.a.); one of the most brilliant star on the firmament of Twelver Shia Faith. It is supposed to be his last writing.

To oppose the tendency to explain how the split in Islam was rooted in perception about the authority of the Prophet, the author explains in fine detail the necessity of declaration, requirements and qualifications of Imamate, the superiority of Ameer al Momineen, and lists the reasons for Indictments of the foremost Caliphs.
