The documentary explores the origins of Islam, an Abrahamic religion that developed in Arabia in the 7th century and criticises the orthodox Islamic account of this history, claiming that the traditional story lacks sufficient supporting evidence. It was commissioned by the British television company Channel 4 and first broadcast in August 2012. Its release followed the publication of Holland's In the Shadow of the Sword: The Battle for Global Empire and the End of the Ancient World (2012), which also discussed the rise of the Arab Empire and the origins of Islam.
