Idolatry is the worship of an idol or image, being a picture, a statue, or a person in place of God. In Judaism, Christianity and Islam, idolatry means worshiping something that is not God. These religions teach that there is only one God. Idolatry is said to be the "worship of false gods". It is forbidden by religious rules such as the Ten Commandments. There it says, "You shall not make a carved image (as a God)" and "You shall not have any other god ahead of Me (the only God). The monotheistic religions all have such rules.
