Do Abarahamic religions share in common the same strict and solid belief of atheism with regard to the worship of of other (specifically multiple) Gods?

I'm not sure what the strict and solid belief of atheism is, but the Abrahamic religions tend to have the view that there is only one God. Often this God is seen as manifesting through multiple spirits, or personas, (the Christian Trinity view, for instance,) but it is commonly believed that these are not different Gods, just different aspects of the same God.

Most practitioners of the Abrahamic religions would not condone worshipping other gods either. There are many scriptures along the lines of worshipping only one God.
