The Koran confirms the existence of the Christian and Jewish Scriptures and demands belief in Jesus, Moses, and all other prophets. As the last Holy Book, the Koran carries a vision of Christianity and Judaism, stating that although these religions had once been similar to Islam, they were tampered with and altered to the form they are in today. There are many verses in the Koran that directly address Christian and Jewish people, refuting their beliefs, and inviting them to submit to Allah.
