As a Muslim, I wanted to understand how Islam is being presented to non-Muslims in an academic way. This is fairly accurate on the fundamentals, but there were several points I would have wanted to correct the professor at, especially in the second half of the course.
I found myself nodding to many points this book makes regarding the misconceptions about Islam that non-Muslims have. While some points can be questioned and could have been presented more clearly, in my opinion, it is a remarkable effort and Professor John Esposito did an admirable job.
