In the Islamic Republic of Iran, the freedom, independence, unity, and territorial integrity of the country are inseparable from one another, and their preservation is the duty of the government and all individual citizens. No individual, group, or authority, has the right to infringe in the slightest way upon the political, cultural, economic, and military independence or the territorial integrity of Iran under the pretext of exercising freedom. Similarly, no authority has the right to abrogate legitimate freedoms, not even by enacting laws and regulations for that purpose, under the pretext of preserving the independence and territorial integrity of the country.

The official religion of Iran is Islam and the Twelver Ja'fari school, and this principle will remain eternally immutable.

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 constitute the majority, local regulations, within the bounds of the jurisdiction of local councils, are to be in accordance with the respective school, without infringing upon the rights of the followers of other schools.

Article 13 [Recognized Religious Minorities]

In accordance with the sacred verse "God does not forbid you to deal kindly and justly with those who have not fought against you because of your religion and who have not expelled you from your homes" [60:8], the government of the Islamic Republic of Iran and all Muslims are duty-bound to treat non-Muslims in conformity with ethical norms and the principles of Islamic justice and equity, and to respect their human rights. This principle applies to all who refrain from engaging in conspiracy or activity against Islam and the Islamic Republic of Iran.
