Translated by: Sayyid Athar Husain S. H. Rizvi
The book was written on the recommendation of Imam of the Age (a.s) as the writer himself describes. The original book is in Arabic, deals with the importance of recognizing the Imam, his specialties and the proofs of his Imamate etc. The later chapters are concerned with the best times and methods of praying for Imam, and lastly on the duties of the Shias towards the Imam of the time.
