One of the most interesting accounts of the early seventh century comes from Sebeos who was a bishop of the House of Bagratunis. From this chronicle, there are indications that he lived through many of the events he relates. He maintains that the account of Arab conquests derives from the fugitives who had been eyewitnesses thereof. He concludes with Mu‘awiya's ascendancy in the Arab civil war (656-61 CE), which suggests that he was writing soon after this date. Sebeos is the first non-Muslim author to present us with a theory for the rise of Islam that pays attention to what the Muslims themselves thought they were doing. As for Muhammad, he has the following to say:
At that time a certain man from along those same sons of Ismael, whose name was Mahmet [i.e., Muḥammad], a merchant, as if by God's command appeared to them as a preacher [and] the path of truth. He taught them to recognize the God of Abraham, especially because he was learnt and informed in the history of Moses. Now because the command was from on high, at a single order they all came together in unity of religion. Abandoning their vain cults, they turned to the living God who had appeared to their father Abraham. So, Mahmet legislated for them: not to eat carrion, not to drink wine, not to speak falsely, and not to engage in fornication. He said: 'With an oath God promised this land to Abraham and his seed after him for ever. And he brought about as he promised during that time while he loved Ismael. But now you are the sons of Abraham and God is accomplishing his promise to Abraham and his seed for you. Love sincerely only the God of Abraham, and go and seize the land which God gave to your father Abraham. No one will be able to resist you in battle, because God is with you.
Sebeos was writing the chronicle at a time when memories of sudden eruption of the Arabs was fresh. He knows Muhammad's name and that he was a merchant by profession. He hints that his life was suddenly changed by a divinely inspired revelation. He presents a good summary of Muhammad's preaching, i.e., belief in one God, Abraham as a common ancestor of Jews and Arabs. He picks out some of the rules of behaviour imposed on the umma; the four prohibitions which are mentioned in the Qur'an. Much of what he says about the origins of Islam conforms to the Muslim tradition.
