And he moves his people to a new city called Medina where he is welcomed. He is brought in as a new leader, somebody that is to unite the Christians and the Jewish people and the different ancient tribes. And this is done according to a constitution called the Constitution of Medina where different things occur, where they start praying towards Mecca instead of Jerusalem, where there is tolerance for other faiths. But there's also the idea that Muhammad's going to be the guy in charge. So it's kind of a balance between a little bit of diversity, but the Muslims really having their first city in Medina. Now in 630 Muhammad's ranks are going to grow. He's going to have about 10,000 people under his command now.
