ABSTRACT
The tremendous growth of Islam in 20th-century America—in which immigration, propagation, and conversions have made it the nation’s third-largest (perhaps second-largest) religion—is a powerful indicator of the expansion of American religion beyond Judeo-Christian tradition. But like Christianity and Judaism, it is a monotheistic, scriptural faith. Teaching submission to God, or Allah, it requires daily prayer facing its birthplace in Mecca, Saudi Arabia, almsgiving, a month of fasting each year, and pilgrimage to Mecca.
