What areas were influenced by Judaism, Islam and Christianity respectively?

Christianity and Islam are the two largest religions in the world and share a historical traditional connection, with some major theological differences. The two faiths share a common place of origin in the Middle East, and consider themselves to be monotheistic.

Christianity is an Abrahamic, monotheistic religion which developed out of Second Temple Judaism in the 1st century CE. It is founded on the life, teachings, death, and resurrection of Jesus Christ, and those who follow it are called Christians.

Muslims have a range of views on Christianity, from viewing Christians to be People of the Book to regarding them as kafirs (infidels) that commit shirk (polytheism) because of Trinitarianism and as dhimmis (religious taxpayers) under Sharia. Christian views on Islam are diverse and range from considering Islam a fellow Abrahamic religion worshipping the same God, to believing Islam to be heresy or an apostatic cult that denies the Crucifixion and rejects the divinity of Christ.

Islam considers Jesus to be al-Masih, the Arabic term for Messiah, sent to guide the Children of Israel (banī isrā'īl in Arabic) with a new revelation: al-Injīl (Arabic for "the Gospel").

Christianity believes Jesus to be the Messiah of the Hebrew scripture, the Son of God, and God the Son, while Muslims consider the Trinity to be a division of God's Oneness and a grave sin (shirk). Muslims believe Jesus (Isa) to be a messenger of God, not the son of God.

Explanation:

Christianity and Islam have different scriptures, with Christianity using the Bible and Islam using the Quran, though Muslims believe that both the Quran and the Christian Gospel, termed Injeel, were sent by God. Both texts offer an account of the life and works of Jesus. The belief in Jesus is a fundamental part of Islamic theology, and Muslims view the Injeel as tahrif (distorted or altered), while Christians consider their Gospels to be authoritative and the Quran to be a later, fabricated or apocryphal work. Both religions believe in the virgin birth of Jesus through Mary, but the Biblical and Islamic accounts differ.
