The title of the video represents the cleric, Omar Gharba, as saying, “We won’t accept anything but Wahhabism in Syria,” but that is not what he says. What he actually says is, “Only Allah will be worshipped in the land of al-Sham [Syria], and only the rule of Allah will be established….We won’t accept anything but Allah, the religion of Allah, and the Sunnah of the prophet of Allah, Muhammad ibn Abdullah.”
Wahhabis present themselves not as the adherents of some sect, but as the authentic embodiment of true Islam. That is how they gain recruits among other Muslims. The way this video is titled obscures that, whether deliberately or not.
