"According to Article 12 of the Constitution of the Islamic Republic, the Twelver Ja’farî school of Islam is the official religion of the country, and this principle will remain “eternally immutable.”1 The very same article also states that adherents of the four major Sunni schools are free to practice their faiths, and that in localities where they are in the majority, local ordinances would be in accordance with their religious beliefs.2 Sunni Muslims are by far Iran's largest religious minority."
