Edward Trimnell's Online Guide to the Middle East
What are the common roots between Judaism, Christianity, and Islam?
The histories of the world’s three major monotheistic religions intersect in the Middle East.
All of them recognize Abraham as the earliest prophet. Tradition holds that Abraham migrated from Mesopotamia (modern-day Iraq) to Canaan (modern-day Palestine around 3000 B.C.E.)
Muslims belief that Allah is the deity described in the Old Testament. Muslims also acknowledge Jesus as a prophet (though they do not ascribe any divinity to him.)
