Dear Fellow,
I wrote "jahangir's book" to have you an overall idea about the topics and course of Muslim Law.But if you are consulting B.A level book as a primary book then consult Mulla's book for detailed study as this book is considered authentic on the subject.Moreover,its easy to understand and contains many relevent examples.But again,some topics are also missing in it.
In my personal opinion go with these two books initially.Later on you can prepare remaining topics from somewhere else.
Or Put your queries on forum.

Yup... I am available for any kind of help in this regard.This is an easy subject and may seem interesting to you too.Its just about management.Look around you you will discover it everywhere.
While preparing for Muslim law ..have a look at these video lectures:

Hope so you will enjoy the scene and please put your Public ad queries in relevent threads.
