Agenda:
Judaism, Christianity, and Islam.

The same part: One God, and the same God, Prophet Abraham, Old Testament.

Why they conflict?


Background info:

Abrahamic religions (also Abrahamism) are the monotheistic faiths emphasizing and tracing their common origin to Abraham[1] or recognizing a spiritual tradition identified with him.[2][3][4] They are one of the three major divisions in comparative religion, along with Indian religions (Dharmic) and East Asian religions (Taoic). As of the early twenty-first century, it was estimated that 54% of the world's population (3.8 billion people) considered themselves adherents of the Abrahamic religions, about 30% of other religions, and 16% of no religion.[5][6]

The three major Abrahamic religions are, in chronological order of founding, Judaism, Christianity, and Islam.

Judaism

Judaism's oldest text is the Tanakh, an account of the Israelites' relationship with God from their earliest history until the building of the Second Temple (c. 535 BCE). Abraham is hailed as the first Hebrew and the father of the Jewish people. One of his great-grandsons was Judah, from whom the religion ultimately gets it name. The Israelites were initially a number of tribes who lived in the Kingdom of Israel and Kingdom of Judah. After being conquered and exiled, some members of the Kingdom of Judah eventually returned to Israel. They later formed an independent state under the Hasmonean dynasty in the 2nd and 1st centuries BCE, before becoming a client kingdom of the Roman Empire, which also conquered the state and dispersed its inhabitants. From the 2nd to the 6th centuries Jews wrote the Talmud, a lengthy work of legal rulings and Biblical exegesis which—along with the Tanakh—is a key text of Judaism.

Christianity

Christianity began in the 1st century as a sect within Judaism initially led by Jesus. His followers viewed him as the Messiah; after his crucifixion and death they came to view him as God incarnate,[52] who was resurrected and will return at the end of time to judge the living and the dead and create an eternal Kingdom of God. Within a few decades the new movement split from Judaism. After several periods of alternating persecution and relative peace vis a vis the Roman authorities under different administrations, Christianity became the state church of the Roman Empire in 380, but has been split into various churches from its beginning. An attempt was made by the Byzantine Empire to unify Christendom, but this formally failed with the East–West Schism of 1054. In the 16th century the birth and growth of Protestantism further split Christianity into many denominations.

Islam

Islam is based on the teachings of the Quran. Although it considers Muhammad to be the Seal of the prophets, Islam teaches that every prophet preached Islam, providing a historical back-story for the religion by co-opting Jewish and Christian prophets, and adding others, such as Cyrus the Great (Dhul-Qarnayn) and al-Khidr. The teachings of Quran are presented as the direct revelation and words of Allah, and earlier scriptures are considered to have been corrupted over time. Islam (meaning "submission", in the sense of submission to Allah) is universal (membership is open to anyone); like Judaism, it has a strictly unitary conception of Allah, called tawhid, or "strict" or "simple" monotheism.[50] Early disputes over who would lead Muslims following the death of Muhammad led to a split between Sunni and Shia, Islam's two main denominations.
