Now Mecca was already seen as kind of a place that people would pilgrimage to, pre-Islamic. But they would be not just Christians and Jews, but pagans, polytheistic people, people that would go to something called the Kaaba. The Kaaba where they would put stones and idols and different worship ceremonies. But it was already a pretty religious place. And in 605 there's a crisis among the different religious leaders. And what had happened is during renovations of the Kaaba they took out something called the Black Stone. And they couldn't agree who gets to put the Black Stone back.
