The writers of the Hadiths were mostly sons of Persians, whose national religion was Zoroastrian, and the hadith is filled with off take copies of Jewish, Zoroastrian, and "Christian" stories. The only draw to the Islam religion was in the form of lower taxes, or in some cases keeping one's head. While there were remnants of the Babylonian Jews, in Hira or that area, as there are even a few today, the majority of converts were from Persia and North Africa, and initially a product of the lower taxes for Muslim believers. It is a religion of monetary policy and having an affinity to keep one's head in place. Today, as with a lot of religions, it is a matter of marriage protocols, and large Muslim families, which continuous the Muslim indoctrination. The Muslim death bell will be due to any increase in wealth, and education. The Muslims fleeing the godless USA will keep their indoctrination, but their children, when exposed to non-Muslim education, and a higher standard of living, will shun blowing themselves up for the greater good. Don't get me wrong, Jews can be bought, but generally not in large numbers. They fled from Spain under the Inquisition, which was similar in circumstance, other than the use of fire versus a sword, and theft versus taxes. The ones who stayed feign obedience to the Pope. The good thing is that the Spanish government in 2015 made a law giving dual citizenship to any Jews expelled in 1490 era expulsion. On the other hand, the Muslims still persecute the Jews in their countries.
