This book is a collection of lectures and writings of the leader Islamic revolution Ayatuallah Syed Ali Khamenei. It consists of 17 chapters. It starts with the life of Prophet Mohammad (P.B.U.H) and ends with Imam Hasan al-Askari (A.S). The first three chapters are about the social and political situation of the Islamic Community. Rehbar analyzes the life of the Ma’sumeen (A.S) as if they were one person who lived for 250 years. The book showcases their lifestyle in scenarios where they apparently exhibit different actions, however essentially are all still going towards one direction and fulfilling one objective. This book allows us to see why and how they followed this one direction and how we can understand it with relation to our lives. The period of 250 years is applied to the tenth lunar Hijri year (631 CE) until the Minor Occultation (874 CE).
