Umar Lee has recently begun an informative series on the history and decline of the salafi movement in the United States. The series is ongoing and currently he has the first 7-parts out on his blog.
I came into Islam after 9/11 and spent much of my first two years in Islam learning by myself about the deen. And I think it would be hard for most Muslims irrespective of their own ideological background in the US to ignore the influence that the often sincere yet not without mistakes salafi dawah has had on the American Muslim community.
I have seen much good and much excess in the salafi movement and did not have a good grasp on how the movement began, flourished, and developed into the state in which I first encountered it. I had done some research into it but Umar Lee’s series has increased my understanding and filled in some gaps and erased some misconceptions that I had about the salafi movement.
The seven posts thus far have been a good quick read and shouldn’t take most people more than 20-30 minutes to get through all of the posts. I highly recommend it.
