Judaism came first of the monotheistic religions. Then Christianity came along, and then Islam. All of these religions believe in the same God, but the word in there native languages use different terms for that reference. Each of those religions have the same teachings really.

Jews = Torah - Hebrew
Christians = Old & New Testament - Trasnslated from Hebrew to Greek
Muslims = Quran - Arabic

Each of these religions have many variants of their "bibles" and each sect in those religions all feel they are the "ones". But in reality... those religions are just built on top of each other and it's only the people who are different.
