What are the main differences between Abrahamic religions?
The main differences between the Abrahamic religions (Judaism, Christianity, and islam) are as follows:

**Founders**
Jewish history is traced to the covenant between God and Abraham, Christianity to Jesus Christ, and Islam to the prophet Muhammad.

**Sacred Texts**
The Jewish faith focuses on the five books of Moses as the central scripture. The New Testament is included in Christianity, including the life and teachings of Jesus. The islamic faith holds the quran to be the primary sacred text, regarded as the revelation of God to Muhammad.

**Belief in Jesus**
Christianity considers Jesus to be the Messiah and the Son of God, while Judaism considers him a teacher or prophet but not a divine being. Islam thinks of Jesus as a prophet, but not as God or the Son of God.

**Concept of God**
All three religions believe in only one God. Nevertheless, the Christian doctrine of the Trinity teaches that God is composed of three persons: Father, Son (Jesus Christ), and Holy Spirit. Both Judaism and islam strongly emphasize the unity of God, without a Trinitarian belief.

**Role of Prophets**
All three religions have prophets, but their importance and teachings are different in each religion. Moses, Isaiah, and Jeremiah are recognized by Judaism. Christianity elevates Jesus as the ultimate prophet and saviour, and islam reveres Muhammad as the last and final prophet, believed to have received the complete revelation from God.

**Salvation and Afterlife**
Christianity teaches that salvation is achieved through faith in Jesus Christ and his sacrificial death and resurrection, which leads to eternal life. In Judaism, salvation is understood as following God's commandments and living a righteous life, with a focus on the present world rather than the afterlife, and islam emphasizes belief in the oneness of God and the obedience to His commands for attaining paradise in the afterlife.
There are some stuff you said that seems wrong to me, can you clarify?
Is Jesus really considered a prophet in Judaism?
Are the first 5 books the central scripture fot Judaism? What about the other books, the Talmud, etc?
Also why don't you capitalize Islam?
