Didn’t ISIL “purge with fire” that Muslim Jordanian pilot?

So the concept is there for using fire to purge. It’s not just Christian.

Very interesting...Purgatory (purification by fire) may have actually been brought back by Crusaders of the first and second Crusades...along with many other Islamic practices like prayer beads and flagellation...

Wikipedia - While use of the word "Purgatory" (in Latin purgatorium) as a noun appeared perhaps only between 1160 and 1180, giving rise to the idea of purgatory as a place[7] (what Jacques Le Goff called the "birth" of purgatory),[8]
