"The survey, which involved more than 38,000 face-to-face interviews in over 80 languages, finds that in addition to the widespread conviction that there is only one God and that Muhammad is His Prophet, large percentages of Muslims around the world share other articles of faith, including belief in angels, heaven, hell and fate (or predestination). While there is broad agreement on the core tenets of Islam, however, Muslims across the 39 countries and territories surveyed differ significantly in their levels of religious commitment, openness to multiple interpretations of their faith and acceptance of various sects and movements."
