Muslims are the followers of Islam that is the religion of Allah (or God in English and same God in Christianity and Judaism). Islam is the oldest God religion in the universe. Islam means full submission to God and to His will. Islam per Torah revelation to Moses is called Judaism. Islam per the Bible revelation to Jesus is called Christianity. Islam per Quran revelation to Muhammad is called the same name Islam as it is the last God religion on earth. Accordingly, Muslims (per Quran revelation to prophet Muhammad) didn't get anything from Judaism and or Christianity. The three religions got their teachings, ritual worships, and morals from the same source that is Allah (or God in English and same God in Christianity and Judaism).
Abrahamic religions include Judaism, Christianity, Islam and the Baha'i faith. Christianity recognize Judaism but not Islam. Islam recognizes Judaism, Christianity but not Baha'i faith. And finally Baha'i faith recognizes Judaism, Christianity and Islam all together. And obviously he did not start anything. He simply preached the word of God, i.e. the holy revelations.
They're similar in the fact that they have one god (Allah in Islam, Yahweh in Christianity.)
