The geometric or floral, interlaced forms, taken together, constitute an infinitely repeated pattern that extends beyond the visible material world. To many in the Islamic world, they symbolize the concept of infinite proves of existence of one eternal God. Furthermore, the Islamic artist conveys a definite spirituality without the iconography of Christian art. Non-figural ornaments are used in mosques and buildings around the Muslim world, and it is a way of decorating using beautiful, embellishing and repetitive Islamic art instead of using pictures of humans and animals (which some Muslims believe is forbidden ("Haram") in Islam).
