Article 12

The official religion of Iran is Islam and the Twelver Ja'fari school [in usual al-Din and fiqh], and this principle will remain eternally immutable. Other Islamic schools, including the Hanafi, Shafi'i, Maliki, Hanbali, and Zaydi, are to be accorded full respect, and their followers are free to act in accordance with their own jurisprudence in performing their religious rites. These schools enjoy official status in matters pertaining to religious education, affairs of personal status (marriage, divorce, inheritance, and wills) and related litigation in courts of law. In regions of the country where Muslims following any one of these schools of fiqh constitute the majority, local regulations, within the bounds of the jurisdiction of local councils, are to be in accordance with the respective school of fiqh, without infringing upon the rights of the followers of other schools.
