The Bible, which is written in two parts, the first half of it is called the Old Testament and the second half the New Testament.
The Old Testament is all the information about the teachings and doings of God before Jesus was born. This is, for all intensive purposes, the core of what Judaism follows.
The New Testament is all the information about the life and teachings and doings of God from a little bit before Jesus was born up to a while after he was crucified. Christians follow the New Testament with referal to and understanding of the Old Testament.
Islam follows the Quran, but accepts The Bible in its entirety as Hadith in the same sort of way Christians accept the Old Testament.
