"Islam is a monotheistic religious tradition that developed in the Middle East in the 7th century C.E. Islam, which literally means "surrender" or "submission," was founded on the teachings of the Prophet Muhammad as an expression of surrender to the will of Allah, the creator and sustainer of the world. "
"The religious rituals of Islam are relatively few in number, but great in importance. The Five Pillars I are five practices regarded by all sects as essential to the Muslim faith. Other notable Islamic practices include the mystical rituals of Sufism and various distinctive Shi'ite practices."
Muslims never keep or have a picture of their god or their prophet.
