You misunderstood this whole thing. Muslims are Gentiles. They are not yehuborim, because yehuborim are a race and not a religion. Their religion, however, is a jewish hoax. Xianity is also a jewish hoax. Both came from Judaism and both have the jewish character Abraham in their texts, and so all 3 are called Abrahamic religions.
The fact that they fight against each other proves they are jewish: Pre-xian Pagan religions were all different yet there were no religious wars before the Abrahamic religions arrived. The mindset of a religion being the "only truth" comes from Judaism, and it's passed to the other two Abrahamic (jewish) religions. So no surprises here, because they have this jewish mindset of theirs being the "only truth", xians even killed other xians whose dogma different in a very small way from their own.
Regarding Islam, Muslims believe yehuborim and xians will go to a lesser heaven, but they'll still go to heaven, contrary to other non-Abrahamists who will burn in their "hell". They also hold yehuborim and xians higher than other religions: according to their Sharia law, Pagans must either convert to Islam or killed. But yehuborim and xians since they both worship their "Allah" will not be killed, but they will have to pay a tax called jizzya and become dhimmis.
