Islam is Deen and Deen means a complete system and a perfect code of life as this is given by the very creator of the worlds, who knows all about his creatures, their qualities, and their shortcomings, and can provide a perfect solution to their problems. But unfortunately, some people have been doing wrong in the name of Khalafat and presenting their wrong idea as the Islamic political system, so there was a great need for a book that can present the proper shape of an Islamic state and Islamic political system given by the Creator; when executed properly, it is a mercy and blessing for the creatures. This book explains this concept clearly.
