It is a must read for muslims living in western countries. The book deals with the issues of BELONGING(specially immigrant muslims), EXTREMELY IMPORTANT concept of Darul Harb and Darul Islam and a thorough discussion of what is required of a muslim living/working/studying in non-muslim lands in general.
He mentions the CORE characteristics that makes muslim ummah, THE BEST NATION i.e. Telling Mankind the real purpose of life and conveying the message of the prophets. When muslims live amongst non-muslims they automatically are calling non-muslims to Islam by the way they act, they work or do any thing else whether they actually call people to Islam or not.
Tariq Ramadhan gives the western muslims confidence and encourages them to stop being isolationist and engage fully in the society around them to make the situation better for themselves as a community and also to fulfill their obligation of transmitting the message of the prophets to their fellow citizens. Even if these concepts are not new to you as a muslim, it is a must to read and reflect upon what brother Tariq says. Our reading, reflecting and then actually DOING DAWAH can make a difference of us entering HELL or entering PARADISE in the hereafter. No matter how bad the situation becomes for muslims and how bad the non-muslims treat muslims, muslims can NEVER EVER forget their obligation to save themselves and the non-muslims from Hellfire and Tariq makes an excellent case for that.
You would for sure like reading this book. I don't agree with each and everything in the book but I pray for him for writing about the core issues we face as muslims. And don't even once look at the price, reading this book is far better then eating at your favorite restaurant.
As the issues indicate the book is primarily for muslims but would help non-muslims too specially the ones interested to find out about muslims in the west in particular and Islam in general. If you are a non-muslim then I would HIGHLY RECOMMEND "What Everyone Should Know About Islam and Muslims" by Suzanne Haneef apart from reading the FINAL REVELATION to mankind, THE HOLY QURAN.
I believe this is one of the best books I have read in a long time. It was the first time a scholar elaborates on what it really means to be both Western and Muslim. He tackles just about every issue facing Muslims in the West - and while obvously not everyone will agree with him - he is the first one to really discuss these issues as far as I know.
