They probably hate Paul for the same reason the Nazis hated him - he had been the Jew Saul before the conversion on the road to Damascus.
From what I understand, their hatred of Jews stems from the direct contradiction between Judaism and Islam. They cannot both be correct. And since all the prophets were Jews (except their false one), they also see Jews as a threat. “In time we hate that which we often fear”. Islam is not about spiritual enlightenment, but is a cult which appeals to the basic animal instinct of “us vs. them”. To be Islamic means you must hate everyone else.
