And now you have this guy, a member of the Quraysh tribe, the tribe that worships Hubal, the tribe that is in charge of Mecca, that benefits from all these people worshiping these various idols, he's now saying that idol worship is a sin, he's saying that there's no God but God, that all of these idols are false idols. And so the Quraysh tribe, Muhammad's own tribe, begins to significantly persecute the early Muslims. So much so that many of the early Muslims have to migrate from Mecca to the kingdom of Aksum, which was ruled by a Christian king who protects them from the Quraysh tribe, this now modern-day Ethiopia or Eritrea. And so things are not going well for these early Muslims. They're really in the, they're being targeted by the Quraysh tribe, they're being killed, they're being tortured. And then things get even worse for Muhammad. In 619, you have the death of his wife, Khadijah.
