No Islamic visual images or depictions of God are meant to exist because it is believed that such artistic depictions may lead to idolatry. Moreover, Muslims believe that God is incorporeal, making any two- or three- dimensional depictions impossible. Instead, Muslims describe God by the names and attributes that, according to Islam, he revealed to his creation. All but one sura of the Quran begins with the phrase "In the name of God, the Beneficent, the Merciful". Images of Mohammed are likewise prohibited. Such aniconism and iconoclasm can also be found in Jewish and some Christian theology.
