Final answer:
Judaism is the belief that laid the foundation for Christianity and Islam, which are collectively known as the Abrahamic faiths. They share Abraham as a common patriarch and have influenced moral thought and world history significantly.
Step-by-step explanation:
The belief that became the foundation of two other great monotheistic religions besides Judaism is Islam and Christianity.
These are among the world's major faiths and share many commonalities including holy sites, like Jerusalem, and figures, such as Abraham, who is a central patriarch in all three religions.
Judaism, the earliest, established the principle of worshipping only one God. Christianity emerged next, with its followers believing in the divinity of Jesus Christ and the Holy Bible, including the Old Testament shared with Judaism.
Finally, Islam, as the youngest of the three, believes in the prophethood of Muhammad and follows the Qur'an as its holiest book.
Abraham is a key figure in the foundation of the Jewish faith, which regards him as the founding patriarch who entered into a covenant with God.
This faith also laid the groundwork for Christianity, with its worship centered on the life and teachings of Jesus Christ, and Islam, which recognizes both Moses and Jesus as prophets, with Muhammad as the final prophet.
The shared lineage and principles underscore the profound role these religions have played in shaping world history and moral thought.
