The Book has a very deep view of different Islamic parties (Sunnah, She3ah, Khawareg & Moatazelah). It tackle how each one understand Ruling and apply it. It also Describes how political situation affect the way of thinking of each group or even help in forming it.
The only problem that the book is detailed and big, I believe it can be in a lighter version of half of its current size. Also the book focus too much in Moatzaelah and how they see the Leader, the people and the agreement between them. His Focus on Sunnah and how they were thinking was not clear for me and was something aside.
