Jesus is God.
Allah is Satan.
The verse I supplied explicitly addresses the deity of Christ. If one is not worshipping Jesus Christ, he is not worshipping the Father. This applies to both Muslims and Jews.
These might even use the words of the Bible to reference "god". They might even claim they are looking forward to a messiah. But, if they deny that Jesus is the Christ (the Messiah), they do not have God. They do not have the Son. They do not have the Father.
Just for clarification’s sake, Allah is simply the Arabic word for God. It’s used by middle eastern Christians as well.
