Shia–Sunni relations

The succession to Muhammad in 632 led the Muslims to be split into two camps: the Sunnis, who believed that the caliphs of the Islamic community should be chosen by a council, as in Saqifa; and a second group, the Shia, who believed that Muhammad had named his successor to be Ali ibn Abi Talib, his cousin and son-in-law. Today there are differences in religious practice and jurisprudence, traditions, and customs between Shia and Sunni Muslims. Although all Muslim groups consider the Quran to be divine, Sunni and Shia have different opinions on interpretations (hadith) of the Quran.[1]

Demographics

Sunni Muslims are the vast majority of Muslims in most Muslim communities in Central Asia (including China). Within Shia Islam about 85% are Twelver, and within Twelver Shia, the overwhelming majority follow the Usuli school of jurisprudence. In Iran, an officially Shia country since 1501, around 90–95% of Muslims are Shia.[1]

Mahdi

The Mahdi is the prophesied redeemer of Islam. While Shia and Sunnis differ on the nature of the Mahdi, many members of both groups believe that the Mahdi will appear at the end of the world to bring about a perfect and just Islamic society.[1]

Hadith

The Shia accept some of the same hadiths of Muhammad used by Sunnis as part of the sunnah and the basis of divine law and religious practice. In addition, they consider the sayings of Ahl al-Bayt that are not attributed directly to Muhammad as hadiths. Shia do not accept many Sunni hadiths unless they are also recorded in Shia sources or the methodology of how they were recorded can be proven.[1]

Sufism

Shiism and Sufism are said to share a number of hallmarks: Belief in an inner meaning to the Quran, special status for some mortals (saints for Sufi, Imams for Shia), as well as veneration of Ali and Muhammad's family.[1]

Pillars of faith

The Five Pillars of Islam (Arabic: أركان الإسلام) is the term given to the five duties incumbent on every Muslim and are held by both Sunni and Shia. These duties are Shahada (profession of faith), Salat (prayers), Zakāt (giving of alms), Sawm (fasting, specifically during Ramadan) and Hajj (pilgrimage to Mecca). In addition, Shia theology has two concepts that define religion as a whole.[1]

Growth in sectarianism

Among the explanations for the growth in sectarianism are conspiracies by outside forces to divide Muslims, the recent Islamic revival and increased religious purity and consequent takfir, upheaval, destruction and loss of power of Sunni caused by the US invasion of Iraq, and sectarianism generated by Arab regimes defending themselves against the mass uprisings of the Arab Spring.[1]

Outside conspiracies

Many in the Muslim world explain the bloodshed as the work of conspiracies by outside forces—"the forces of hegemony and Zionism which aim to weaken [Arabs]" (Akbar Hashemi Rafsanjani and Yusuf al-Qaradawi), unspecified "enemies" (Iran president Mahmoud Ahmadinejad), or "oppressive pressure by the imperialist front." (Mahmoud Ahmadinejad).[1]

History of shia iran

Early and pre-modern history

The origin of Shia Islam arose in response to the succession to Muhammad and whether Ali ibn Abi Talib or a more experienced member of the Quraysh tribe should succeed. The concept of Shi'ism further crystallized around events at the Battle of Karbala (680 CE) where Husayn ibn Ali, the son of Ali and grandson of Muhammad, was killed alongside many of his supporters. Thus a political split became a far more personal one, marked by blood feud, and a cause for further divergence.[1]

Iran, officially the Islamic Republic of Iran, and historically known as Persia, is a country in West Asia. It borders Iraq to the west; Turkey, Azerbaijan, and Armenia to the northwest; the Caspian Sea to the north, Turkmenistan to the northeast; Afghanistan to the east; Pakistan to the southeast; and the Gulf of Oman and the Persian Gulf to the south. With a population of over 92 million, Iran ranks 17th globally in both geographic size and population.[8]

Prehistory

The earliest known presence of hominins in Iran dates to around 800,000 years ago, in the Middle Paleolithic. Many Middle Paleolithic sites have been discovered, mainly in the Zagros Mountains in western Iran and some sites associated with Neanderthals. The Zarzian culture is documented in Iran during the Epipaleolithic (25,000–11,500 years ago).[8]

Antiquity

Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 4000 BC, including the Jiroft culture in southeastern Iran. Inscriptions in the Proto-Elamite script, which predates cuneiform, have been found from the early third millennium BC. The western part of the Iranian plateau participated in the traditional ancient Near East with Elam (3200–539 BC), and later with other peoples such as the Kassites, Mannaeans, and Gutians.[8]

Medieval period

Most of the Sasanian Empire's lifespan was overshadowed by the frequent Byzantine–Sasanian wars, a continuation of the Roman–Parthian Wars. The last of these wars ultimately contributed to the empire's fall, which culminated with the Islamic conquest of Persia. The Rashidun Caliphate conquered the Sasanian Empire between 632 and 654.[8]

Safavid conversion of Iran to Shia Islam

Following their rise to power in Iran in the 16th century, the Safavid dynasty initiated a campaign of forced conversion against the Iranian populace, seeking to replace Sunni Islam, whose Shafi'i school of jurisprudence pervaded the country, as the denomination of the majority of the population. Over the course of three centuries, the Safavids (who were Twelver Shias) heavily persecuted Sunni Muslims, Jews, Christians, and other religious groups, eventually transforming Iran into a bastion of Shia Islam. This process led to hostilities with Iran's Sunni-majority neighbours, most notably the Ottoman Empire.[11]

Background

After the Islamic prophet Muhammad died in 632, a group of followers (Shia) of his cousin Ali proclaimed the latter as the legitimate heir and caliph. But the hopes of this group were not achieved for thirty years, during which time Abu Bakr, Umar, and Uthman—three of the Prophet's Companions—became caliphs. Sunni Islam was eventually represented by these caliphs.[11]

Under Ismail I

During the reign of the first Safavid shah (king), Ismail I (r. 1501–1524), the military, political, and religious goals of the Safavids became unified. In 1501, he proclaimed himself the King of Kings and the creator of a new Shia state, thus creating a strong ideological foundation.[11]

Under Tahmasp I

In 1524, Ismail I was succeeded by his son Tahmasp I (r. 1524–1576). It was during his rule that Shia Islam in Iran solidified itself.[11]

Under Ismail II

Tahmasp I was succeeded by his son Ismail II (r. 1576–1577), who immediately decided to overturn many of the religious policies established by his father and grandfather. He opted for a kinder approach toward Sunnis and attempted to halt the anti-Sunni propaganda that had gained popularity under his father.[11]

Under Mohammad Khodabanda and Abbas the Great

Ismail II was succeeded by Tahmasp's eldest son, Mohammad Khodabanda (r. 1578–1587), under whom Twelver Shia Islam was restored as the official religion of the realm. By the early reign of Abbas the Great in the end of the 16th century, the majority of Iranians had accepted Shia Islam and virtually, Sunni Islam had disappeared from the central Safavid provinces, only remaining on the outskirts of the realm, such as in Kurdistan, Afghanistan and Baluchistan.[11]

Under Soltan Hoseyn

The religiosity of Soltan Hoseyn (r. 1694–1722) is implied through the numerous awqaf he gifted. He may not have been as intolerant as he commonly is described, as implied by his trust in the Sunni grand vizier Fath-Ali Khan Daghestani, his interest when visiting to the Armenian churches of New Jolfa, as well as the numerous decrees (farman) he declared, which protected the Christian population of Iran and allowed Catholic missionaries to perform their work.[11]

The status, practices and reception of the Shia ulama

Even after two centuries of Persianization, the cultural orientation of the Shia ulama remained largely unchanged. Masquerading with their madrasa (religious school) education, they displayed an anti-intellectual attitude through a strong focus on hadith, conservatism, ritualistic practices in Shia Islam, opposition against diversity, and a heavy emphasis on the stories of the Imams' suffering. It was characteristic of their sociocultural stance that they were hostile to Persian literary and artistic endeavors and treated even ordinary Shia Muslims with disrespect.[11]

Immigration of Arab Shia scholars from Jabal Amil

The Arab Shia scholars of Jabal Amil in Southern Lebanon proved to be eager allies and supporters for Ismail I and his advisors. After years of persecution in their own country by the Mamluks and then the Ottomans, they found a benefactor in Ismail I and a place of luxury and esteem in Safavid Iran. The Amilis (and Arab scholars from other regions) were intentionally placed in important religious and quasi-administrative positions by the early Safavid Shahs, so that they could spread their well-defined Islamic creed rooted in the Shia school of thought (madhhab).[11]

Shia scholars from Mazandaran, including the Mar'ashis

In the 1530s and 1540s, the Safavid household was under heavy influence by the Uskuya sayyids of Tabriz. A new network of sayyids, mostly from Mazandaran, rose to prominence in politics and administration with the capital shift to Qazvin in the 1550s. In recent scholarship, greater attention has been given to the increasing influence of the Mazandarani religious elite within the Safavid state, a subject historically overshadowed by the focus on theologians from Jabal Amil.[11]
