Allah
In Judaism, God is usually called YHWH (by scholarly convention pronounced Yahweh) and Eloah. Both names are mentioned in the Old Testament and are one of the seven names of God in Judaism. It can also be noted that in Judaism, Elohim is a name for God and in Islam, Allahuma is a name for God. Since Jewish and Muslim names of God are very similar, Jews and Muslims say that they believe in the same God.
