Christianity in Arabia

Addas was a Christian slave from Nineveh, owned by one of the sons of Rabi'a of Mecca, who served grapes to Prophet Muhammad in an orchard outside Ta'if and recognised his prophethood from his knowledge of Jonah.

Waraqah ibn Nawfal, a Christian scholar of Mecca and cousin of Khadijah, identified the first revelation to Prophet Muhammad as the same that had come to Moses, and the Prophet later said he had seen him in Paradise, wearing white.
