Judaism, Christianity, and Islam religions.
Judaism, Christianity and Islam. Though Islam doesn't view Jerusalem in the same manner as Judaism or Christianity. For Judaism and Christianity, Jerusalem is place of the world's foundation and the city where G-d's presence once rested. Islam's holy city is actually Mecca, in Saudi Arabia. Islam's claim to Jerusalem is political, not religious (or at least not at all in the way Christians and Jews view Jerusalem).
For Judaism and Christianity it is Jerusalem. For Islam it is Mecca.
-- Islam -- Judaism -- Christianity
Christianity and Judaism
Abraham is considered the father of Judaism, Christianity and Islam as the Old Testament's 5 books of Moses - The Pentateuch (books are: Genesis, Exodus, Leviticus, Numeri and Deuteronomy) are included in the Holy Book of Judaism that is Torah. Eventually he is considered as the father of Islam basically claims entire religions of Judaism and Christianity as "prophets" and predecessors of Islam.
The question should be " What does Christianity have to do with Jews (or Judaism)?" Judaism is like a tree where Christianity is its branch and Islam is it leaves. Christianity is based on Judaism and Islam is based on Christianity. The major difference between the three is that Judaism doesn't have jesus in it unlike Christianity and Islam.
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).
