From my understanding a torah scroll written by a heretic has no sanctity and should be burned (Gittin 45b). May one read torah related material, written by a heretic but that contains nothing heretical, in the bathroom? Similarly may one read the koran in the bathroom since the Koran contains references to Allah which is ostensibly the same thing as Hashem (as opposed to "in God we trust" on currency which is a generic term)?
possibly related - Is there any difference between Jewish G-d and Muslim G-d?
