Al Salamu 'Alaykum.
A question that frequently crops up among the wider Muslim community is of the identity of the Barelwis. The Deobandis are well-known throughout the Islamic world because they are a scholarly group and their books have carried their identity far and wide. Since the Barelwis are a non-scholarly group, usually operating locally at a sub-intellectual level with no connection to the Qur'an and Sunna, their beliefs and acts are often incomprehensible to the Muslims outside the Indo-Pak region. Mawlana Ilyas Ghuman has written a book on this firqa-e-batilah and put it online for Urdu readers. I hope that an English translation will come up soon.
