What?
This allah is a demon, and so is his cult.
I am talking about two words, in Hebrew and Arabic, that have essentially identical meanings.
As I said, you are perfectly free to decide the person Muslims actually worship is really a demon. But you are not free to claim that since the Hebrew Bible does not use a word in a language that did not exist at the time, it “proves” something about Jewish/Muslim comparative claims to the Holy Mount.
IOW, while I agree with the author’s conclusions, some of his arguments are illogical or irrelevant.
