"The Constitution of the Islamic Republic of Iran advances the cultural, social, political, and economic institutions of Iranian society based on Islamic principles and norms, which represent an honest aspiration of the Islamic Ummah. This aspiration was exemplified by the nature of the great Islamic Revolution of Iran, and by the course of the Muslim people's struggle, from its beginning until victory, as reflected in the decisive and forceful calls raised by all segments of the populations. Now, at the threshold of this great victory, our nation, with all its beings, seeks its fulfillment."
