The worshippers of Muhammad believe that Jews and Christians are guilty of what is called in Arabic “tahrif.” That means “forgery.” In other words, we forged the OT and NT in order to hide the “coming” of Muhammad.
There can be no theological debate with members of a religion who accuse other religions of forgery.
True, and the assertion is so patently ludicrous, it kind of implies that trying to debate someone who believes it using logic is going to be quite fruitless.
