This book is about the history of the conflict between Shia sects, how different sects originated and what are the basic beliefs of world known Usuli Shia sect i.e. State religion of Iran, and how it differs from the True Shia religion. Usuli sect was founded only 10 centuries ago, and only 5 or 6 so-called Shia scholars accepted it in 4th and 5th Hijra century. After that for many centuries Shia scholars and public hated this man-made religion. Only few centuries ago Allama Hilli and his company propagated it again, and he was the first to call himself Ayatollah (which is forbidden in Islam). Baqir Behbahani used power and all other tactics to suppress the Shia religion and occupied shia institutions and mosques, so Usuli sect dominated. What are the true teachings of Shia Islam. The religion presented and practiced by Iranian government is not the Tru Shia Islam, infact they are the biggest enemies of Allah, Infallibles asws and Muslims.
