And we saw in 615, the migration of some of Muhammad's followers to Abyssinia, the kingdom of Aksum, modern-day Eritrea in Ethiopia, to escape some of that persecution. Things got worse for Muhammad. We saw in that last video the death of his first wife, and up to that point, his only wife. And this is where we start to see a bit of a turning point for Muhammad and his followers. In 620, and this is according to Muslim traditions, there isn't historical evidence for this, and this is one of the more metaphysical events that we'll talk about in this narrative. But according to the Islamic faith, in 620, Muhammad had a night journey from Mecca to the farthest mosque, which today is believed by many Muslims to be the Al-Aqsa Mosque, which was built later in Jerusalem. So right, right, let me, right over here.
