To give an actual example, in Bosnia the leader of the Salafi movement has been arrested for recruiting for ISIS.
Ask any mainstream Muslim who the Salafi scholars are in recent times and undoubtedly one of the first names mentioned would be the late Ibn Baz.
Ibn Baz was a harsh critic of Bin Laden and his ideology: https://en.wikipedia.org/wiki/Abd_al-Aziz_ibn_Baz#Osama_bin_...
Here is confirmation from Al Fawzan (the most-respected Saudi scholar now) regarding Ibn Baz's (and his own) position with respect to Bin Laden: https://www.youtube.com/watch?v=1-a65Og2uow
Here is a translated video that includes the speech of a late Yemeni scholar, Muqbil Al Wadi'ee, regarding Bin Laden. It's worth listening to: https://www.youtube.com/watch?v=BO7BcXTc4zw
My point is that anyone can call themselves or ascribe themselves to anything. However, that doesn't necessarily make it a reality (yeah, yeah, no true Scotsman).
Counterargument: "No true Christian" could ever kill an enemy - Jesus was clear in this: turn the other cheek, die on the cross if need be, forgive 70 times 7 times, etc. In my sect, Christianity is totally pacifist. All true Christians are pacifists.
So there's no reason for any Muslim to harbor any enmity against any Christians, because no Christians have ever once harmed a Muslim (by my definition of Christians).
...
And so we're back to square one, arguing over who's really a Scotsman....
It's very funny how this usually ends with apologetic excuses
Actions speak louder than words, and there's an awful amount of Salafists preaching for ISIS
Details of religious cults are not interesting to me and I don't care what some guy in the desert (any of them) wrote in a book thousands of years ago.
This. From the outside, it looks like a conflict within Salafism.
It's hardly the only movement such things have happened to (eg revolutionary socialism vs reformist socialism).
