The world's fastest growing religion is either Islam (if considering annual growth in total numbers) or Mormonism (if considering annual growth in percentage terms). Although no references to Islam exist in the Church's canonized books of scripture, many can be found in Mormon sermons and writings. The positions and tones embedded therein are not homogeneous—but represent sundry views expressed in a variety of circumstances over the Church's 171-year life span. The adaptations vary according to the particular eras, issues, and officers. In short, enough different Mormon associations with Islam have occurred to warrant a critical investigation into them.
