I read tehse two terms in another thread and was unfamiliar with them and also I read that there are different types of deobandi who oppose each other so without any arguements, could someone give me an article or detailed explanation on this issue, its origins, what thet differ over, how big the groups are etc, inshAllah a detailed analysis of this as its news to me and I never heard of it before this thread: http://www.sunniforum.com/forum/show...rustami-Salafi
