Imamate in Shia doctrine in the context of "Early Muslims"

Alawites (Arabic: العلويون, romanized: al-ʿAlawiyyūn) are an ethnoreligious group who live primarily in the Levant region in West Asia and follow Alawism, an offshoot of Shia Islam as a ghulat branch during the ninth century. Alawites venerate Ali ibn Abi Talib, the "first Imam" in the Twelver school, as a manifestation of the divine essence. It is the only ghulat sect still in existence today. The group was founded during the ninth century by Ibn Nusayr, who was a disciple of the tenth Twelver Imam, Ali al-Hadi, and of the eleventh Twelver Imam, Hasan al-Askari. For this reason, Alawites are also called Nusayris, although this term can be considered derogatory in the present day.

Surveys suggest Alawites represent an important portion of the Syrian population and are a significant minority in the Hatay Province of Turkey and northern Lebanon. There is also a population living in the village of Ghajar in the Golan Heights, where there had been two other Alawite villages (Ayn Fit and Za'ura) before the Six-Day War. The Alawites form the dominant religious group on the Syrian coast and towns near the coast, which are also inhabited by Sunnis, Christians, and Ismailis. They are often confused with the Alevis, a religious group in Turkey that shares certain similarities with the Alawites but has key differences.

Ali ibn Abi Talib (Arabic: عَلِيُّ بْن أَبِي طَالِب, romanized: ʿAlī ibn Abī Ṭālib) (c. 600 – 661 CE) was the fourth Rashidun caliph who ruled from 656 CE until his assassination in 661, as well as the first Shia Imam. He was the cousin and son-in-law of the Islamic prophet Muhammad. Born to Abu Talib ibn Abd al-Muttalib and Fatima bint Asad, Ali was raised by his elder cousin Muhammad and was among the first to accept his teachings.

Ali played a pivotal role in the early years of Islam when Muslims were severely persecuted in Mecca. After the immigration (hijra) to Medina in 622, Muhammad gave his daughter Fatima to Ali in marriage and swore a pact of brotherhood with him. Ali served as Muhammad's secretary and deputy in this period, and was the flag bearer of his army. Numerous sayings of Muhammad praise Ali, the most controversial of which was uttered in 632 at the Ghadir Khumm, "Whoever I am his mawla, then Ali is his mawla." The interpretation of the polysemous Arabic word mawla is disputed: For Shia Muslims, Muhammad thus invested Ali with his religious and political authority, while Sunni Muslims view this as a mere statement of friendship and rapport. When Muhammad died in the same year, a group of Muslims met in the absence of Ali and appointed Abu Bakr (r. 632–634) as their leader. Ali later relinquished his claims to leadership and resigned from public life during the reigns of Abu Bakr and his successor, Umar (r. 634–644). Even though his advice was occasionally sought, the conflicts between Ali and the first two caliphs are epitomized by his refusal to follow their practices. This refusal cost Ali the caliphate to the benefit of Uthman (r. 644–656), who was thus appointed to succeed Umar by the electoral council. Ali was also highly critical of Uthman, who was widely accused of nepotism and corruption. Yet Ali also repeatedly mediated between the caliph and the provincial dissidents angered by his policies.

The holiest sites in Islam are located in the Middle East. While the significance of most places typically varies depending on the Islamic sect, there is a consensus across all mainstream branches of the religion that affirms three cities as having the highest degree of holiness, in descending order: Mecca, Medina, and Jerusalem. Mecca's Al-Masjid al-Haram (including the Kaaba), Al-Masjid an-Nabawi in Medina, and Jerusalem's Al-Aqsa Mosque are all revered by Muslims as sites of great importance.

After the consensus on the first three sites as well as further sites associated with the family of Muhammad, there is a divergence between Sunni Muslims and Shia Muslims on the designation of additional holy sites. Even within each sect, there are disputes as to whether any uniquely holy cities exist apart from the aforementioned three. For Sunnis that argue that there are, sites associated with the Rashidun, other Companions of Muhammad, and Biblical prophets often hold a high level of significance (see holiest sites in Sunni Islam). In particular, the Umayyad Mosque in the city of Damascus and the Ibrahimi Mosque in the city of Hebron have held interchangeable significance as the fourth and fifth-holiest Islamic sites, respectively, for many Sunni Muslims. For Shias, sites associated with the Imamah hold a high level of significance (see holiest sites in Shia Islam).

Political aspects of the religion of Islam are derived from its religious scripture (the Quran holy book, ḥadīth literature of accounts of the sayings and living habits attributed to the Islamic prophet Muhammad, and sunnah), as well as elements of political movements and tendencies followed by Muslims or Islamic states throughout its history. Shortly after its founding, Islam's prophet Muhammad became a ruler of a state, and the intertwining of religion and state in Islam (and the idea that "politics is central" to Islam), is in contrast to the doctrine of rendering "unto Caesar what belongs to Caesar and to God what belongs to God", of Christianity, its related and neighboring religion.

Traditional political concepts in Islam which form an idealized model for Islamic rule, are based on the rule of Muhammad in Mecca (629–632 CE) and his elected or selected successors, known as rāshidūn ("rightly-guided") caliphs in Sunnī Islam, and the Imams in Shīʿa Islam. Concepts include obedience to the Islamic law (sharīʿa); the supremacy of unity, solidarity and community, over individual rights and diversity; the pledging of obedience by the ruled to rulers (al-Bayʿah), with a corresponding duty of rulers to rule justly and seek consultation (shūrā) before making decisions; and the ruled to rebuke unjust rulers. Classical Islamic political thought focuses on advice on how to govern well, rather than reflecting "on the nature of politics".

Taqlid (Arabic: تقليد, romanized: Taqlīd) is a term used in Islamic jurisprudence to denote the conformity of one person to the teaching of another. As such, the person who performs taqlid is termed muqallid. The definite meaning of the term varies depending on context and age. Classical usage of the term differs between Sunni Islam and Shia Islam. Sunni Islamic usage designates the unjustified conformity of one person to the teaching of another, rather than the justified conformity of a layperson to the teaching of a mujtahid (a person who is qualified for independent reasoning). Shia Islamic usage designates general conformity to the teaching of a mujtahid, and there is no negative connotation. The discrepancy corresponds to differing views on the Shia Imamate and Sunni imams.

In contemporary Salafi usage, taqlid is often portrayed in a negative light and translated as "blind imitation". This refers to the perceived stagnation of independent effort (ijtihad) and uncritical imitation of traditional religious interpretation by the religious establishment in general.

Ismailism, known historically and among practitioners as Esotericism, is a branch of Shia Islam. Like all Shia, the Ismailis emphasize a distinction between the exoteric (zahir) and esoteric (batin) dimension of Islam, and hold that the esoteric meaning was preserved from corruption by a line of descendants of Muhammad (imams). However, unlike other Shia, the Ismaili are characterized by a unique emphasis on the esoteric that approaches antinomianism.

The Isma'ili (/ˌɪzmɑːˈɪliː/) get their name from their acceptance of Imam Isma'il ibn Jafar as the appointed spiritual successor (imām) to Ja'far al-Sadiq, wherein they differ from the Twelver Shia, who accept Musa al-Kazim, the younger brother of Isma'il, as the true Imām.
