And in those days Heraclius saw a dream in which it was said to him: “Verily there shall come against you a circumcised nation, and they shall vanquish you and take possession of the land.” So Heraclius thought that they would be the Jews, and accordingly gave orders that all the Jews and Samaritans should be baptized in all the provinces which were under his dominion. But after a few days there appeared a man of the Arabs, from the southern districts, that is to say, from Mecca or its neighbourhood, whose name was Muhammad; and he brought back the worshippers of idols to the knowledge of the One God, and bade them declare that Muhammad was his apostle; and his nation were circumcised in the Hesh, not by the law, and prayed towards the South, turning towards a place which they called the Kaabah.
