Of course, but is he Sunni or is he Shia?
If he is a member of the Muslim Brother, he is more than likely either a Salafist or a wahabist. Both claim to be of the sect Sunni but neither are. People claim neither exists but Saudi Arabia is proof that they are both alive and well. For more information about this read Dori Gold’s book about the subject on Wahabi’s (sorry the title of the book escapes me at the moment and I really don’t want to dig through my boxes to get the title.)
FYI Al-Qaeda is Wahabi and ISIS more resembles Salafi which is a more violent sect than the Wahabis.
