Although "Judaism birthed both Christianity and Islam", the "three monotheistic faiths went their separate ways". The three faiths "understand the role of Abraham" in "differing ways", and the relationships between Judaism and Christianity and between Judaism and Islam are "uneven".
According to tradition, the Islamic prophet Muhammad was born in Mecca around the year 570. His family belonged to the Quraysh. When he was about forty years old he began receiving what Muslims regard as divine revelations delivered through the angel Gabriel, which would later form the Quran.
