Islam, a major world religion, founded in Arabia and based on the teachings of Muhammad, who is called the Prophet. Muslims follow the Koran, the written revelation brought by Muhammad.
The Muslim world population is estimated at more than 1 billion. Judaism is one of the world's oldest religious traditions.
Pre-modern Judaism constituted (and traditional Judaism today constitutes) an integrated cultural system of Jewish law, custom, and practice encompassing the totality of individual and communal existence.
It is a system of sanctification in which all is to be subsumed under God's rule.
Jesus of Nazareth, a Jewish rabbi, attracted a following of people who believed him to be a new prophet.
Their recollections of Jesus' words and deeds recall his days on earth and the miracle of his resurrection from the dead on the first Easter.
Muhammad began his ministry at the age of 40, when, he claimed, the archangel Gabriel appeared to him in a vision.
At first Muhammad confided his visions only to his family and close friends.
Its deity was Yahweh, the god of the patriarchs, who was worshipped in a sacrificial cult centered in Jerusalem and later at sanctuaries in the north, where a rival Jewish kingdom was formed.
Prophets who warned against the people's reliance on these temple cults saw themselves vindicated when both the northern and southern kingdoms were destroyed by foreign conquerors.
