Islam is the dominant religion in Indonesia, which also has a larger Muslim population than any other country in the world, with approximately 202.9 million identified as Muslim (88.2% of the total population) as of 2009.

The majority adheres to the Sunni Muslim tradition mainly of the Shafi'i madhhab. Around one million are Shias, who are concentrated around Jakarta. In general, the Muslim community can be categorized in terms of two orientations: "modernists," who closely adhere to orthodox theology while embracing modern learning; and "traditionalists," who tend to follow the interpretations of local religious leaders (predominantly in Java) and religious teachers at Islamic boarding schools
