The wahabbism of the saudis, that they've exported, is a relatively new movement though, and not one traditionally practiced in Islam in the region though, atleast through my studies.
Well, I'll say it as politely as possible. Your studies are full of shyt. Since the Afghanistan war on the soviets the Saudi cancer started pumping wahhabi money, mosques, clerics and weapons, the Holy trinity of this pig shyt of an ideology into the area.
As of the mid 80's Afghanistan and Pakistan became strongholds for wahhabi Islam aka Salafi Islam.
In Egypt once these little dogs were set free from a dictator they voted for the Salafis into power, showing once again how Wahhabi Islam has spread at an insane rate.
In Syria the god Bashar Al Assad doesn't have enough bombs to kill them all. There's just too many flocking from all over the world seeking their after life virgins.
fukk these studies you've water your time on, go study butterflies or a cure to cancer you're wa sting your time studying a none curable cancer.
At least Shia Islam seems to have taken the better road, otherwise we would be in deep shyt
