" [A] history of Islam's origins cannot be written without reference to the origins of Judaism and Christianity - and [...] a history of the origins of Judaism and Christianity cannot be written without reference to the world that incubated them both. The vision of God to which both rabbis and bishops subscribed, and which Muhammad's followers inherited, did not emerge out of nowhere. The monotheisms that would end up established as state religions from the Atlantic to central Asia had ancient, and possibly unexpected, roots. To trace them is to cast a searchlight across the entire civilisation of late antiquity. "
