Iran Religions
To talk about Iran Religions; we should stated that overwhelming majority of Iranians; at least 90 percent of the total population are Muslims who adhere to Shia Islam. In contrast, the majority of Muslims throughout the world follow Sunni Islam. Of the several Shia sects, the Twelve Imam or Twelver (ithna- ashari), is dominant in Iran; most Shias in Bahrain, Iraq, and Lebanon also follow this sect. All the Shia sects originated among early Muslim dissenters in the first three centuries following the death of the Prophet Muhammad in A.D. 632.
To add more information about Iran Religions; the principal belief of Twelver’s, but not of other Shias, is that the spiritual and temporal leadership of the Muslim community passed from Muhammad to Ali and then sequentially to eleven of Ali’s direct male descendants, a tenet rejected by Sunnis. Over the centuries various other theological differences have developed between Twelver Shias and Sunnis.
Iran Religions; Shia:
Although Shias have lived in Iran since the earliest days of Islam, and there was one Shia dynasty in part of Iran during the tenth and eleventh centuries, it is believed that most Iranians were Sunnis until the seventeenth century. The Safavid dynasty made Shia Islam the official state religion in the sixteenth century and aggressively proselytized on its behalf. It is also believed that by the mid-seventeenth century most people in what is now Iran had become Shias, an affiliation that has continued.
All Shia Muslims believe there are seven pillars of faith, which detail the acts necessary to demonstrate and reinforce faith. The first five of these pillars are shared with Sunni Muslims. They are shahada, or the confession of faith; namaz, or ritualized prayer; zakat, or almsgiving; sawm, fasting and contemplation during daylight hours during the lunar month of Ramazan; and hajj, or pilgrimage to the holy cities of Mecca and Medina once in a lifetime if financially feasible. The other two pillars, which are not shared with Sunnis, are jihad–or crusade to protect Islamic lands, beliefs, and institutions, and the requirement to do good works and to avoid all evil thoughts, words, and deeds.
Iran Religions; Sunni:
Sunni Muslims constitute approximately 8 percent of the Iranian population. A majority of Kurds, virtually all Baluchis and Turkomans, and a minority of Arabs are Sunnis, as are small communities of Persians in southern Iran and Khorasan. The main difference between Sunnis and Shias is that the former do not accept the doctrine of the Imamate. Generally speaking, Iranian Shias are inclined to recognize Sunnis as fellow Muslims, but as those whose religion is incomplete. Shia clergy tend to view missionary work among Sunnis to convert them to true Islam as a worthwhile religious endeavor. Since the Sunnis generally live in the border regions of the country, there has been no occasion for Shia-Sunni conflict in most of Iran. In those towns with mixed populations in West Azarbaijan, the Persian Gulf region, and Baluchestan va Sistan, tensions between Shias and Sunnis existed both before and after the Revolution. Religious tensions have been highest during major Shia observances, especially Moharram.
