A new Pew Research Center survey of Muslims around the globe finds that most adherents of the world’s second-largest religion are deeply committed to their faith and want its teachings to shape not only their personal lives but also their societies and politics. In all but a handful of the 39 countries surveyed, a majority of Muslims say that Islam is the one true faith leading to eternal life in heaven and that belief in God is necessary to be a moral person. Many also think that their religious leaders should have at least some influence over political matters. And many express a desire for sharia – traditional Islamic law – to be recognized as the official law of their country.

The percentage of Muslims who say they want sharia to be “the official law of the land” varies widely around the world, from fewer than one-in-ten in Azerbaijan (8%) to near unanimity in Afghanistan (99%). But solid majorities in most of the countries surveyed across the Middle East and North Africa, sub-Saharan Africa, South Asia and Southeast Asia favor the establishment of sharia, including 71% of Muslims in Nigeria, 72% in Indonesia, 74% in Egypt and 89% in the Palestinian territories.
