Shia Islam

It holds that Muhammad designated Ali ibn Abi Talib (r. 656–661) as his successor (khalifa) as the imam, that is the spiritual and political leader of the Muslim community.

Later events such as Husayn's martyrdom in the Battle of Karbala (680 CE) further influenced the development of Shia Islam, contributing to the formation of a distinct religious sect with its own rituals and shared collective memory.

Significant Shia communities are also found in Lebanon, Bahrain, Kuwait, Turkey, Yemen, Saudi Arabia, Afghanistan and the Indian subcontinent.

[15] The Shia, originally known as the "partisans" of ʿAlī ibn Abī Ṭālib, Muhammad's cousin and Fatima's husband, first emerged as a distinct movement during the First Fitna from 656 to 661 CE.

[19] With the murder of ʿUthmān in 657 CE, the Muslims of Medina invited ʿAlī to become the fourth caliph as the last source,[27] and he established his capital in Kufa.

[19] Tensions eventually led to the First Fitna, the first major civil war between Muslims within the empire, which began as a series of revolts fought against ʿAlī.

[38][39] According to this view peculiar to Shia Islam, there is always an Imam of the Age, who is the divinely appointed authority on all matters of faith and law in the Muslim community.

Jesus, who is considered the Masih ("Messiah") in Islam, will descend at the point of a white arcade east of Damascus, dressed in yellow robes with his head anointed.

In the century following the Battle of Karbala (680 CE), as various Shia-affiliated groups diffused in the emerging Islamic world, several nations arose based on a Shia leadership or population.

They believe God chose ʿAlī ibn Abī Ṭālib to be Muhammad's successor and the first caliph (Arabic: خليفة, romanized: khalifa) of Islam.

ʿAlī is regarded as a "perfect man" (Arabic: الإنسان الكامل, romanized: al-insan al-kamil) similar to Muhammad, according to the Shīʿīte perspective.

[69] The Occultation is an eschatological belief held in various denominations of Shīʿa Islam concerning a messianic figure, the hidden and last Imam known as "the Mahdi", that one day shall return on Earth and fill the world with justice.

Twelver Shīʿa Muslims believe that the prophesied Mahdi and 12th Shīʿīte Imam, Hujjat Allah al-Mahdi, is already on Earth in Occultation, and will return at the end of time.

[72][73] Shīʿa Muslims believe that the armaments and sacred items of all of the Abrahamic prophets, including Muhammad, were handed down in succession to the Imams of the Ahl al-Bayt.

[74] Al-Ṣādiq also narrated that the passing down of armaments is synonymous to receiving the Imamat (leadership), similar to how the Ark of Covenant in the house of the Israelites signaled prophethood.

Most of the Shīʿa sacred places and heritage sites in Saudi Arabia have been destroyed by the Al Saud-Wahhabi armies of the Ikhwan, the most notable being the tombs of the Imams located in the Al-Baqi' cemetery in 1925.

[86] Shi'ite theologians and mujtahids (jurists), such as Muḥammad Bāqir Majlisῑ, held that Jews' impurity extended to the point where they were advised to stay at home on rainy or snowy days to prevent contaminating their Shia neighbors.

Ayatollah Khomeini, Supreme Leader of Iran from 1979 to 1989, asserted that every part of an unbeliever's body, including hair, nails, and bodily secretions, is impure.

A significant Shia minority is present in Nigeria, made up of modern-era converts to a Shīʿīte movement centered around Kano and Sokoto states.

hold small minority populations of various Shia subsects, primarily descendants of immigrants from South Asia during the colonial period, such as the Khoja.

All mainstream Twelver and Ismāʿīlī Shia Muslims follow the same school of thought, the Jaʽfari jurisprudence, named after Jaʿfar al-Ṣādiq, the 6th Shīʿīte Imam.

[59] These five principles known as Usul ad-Din are as follow:[137] Besides the Quran, which is the sacred text common to all Muslims, Twelver Shias derive scriptural and authoritative guidance from collections of sayings and traditions (hadith) attributed to Muhammad and the Twelve Imams.

Below is a list of some of the most prominent of these books: According to the theology of Twelvers, the successor of Muhammad is an infallible human individual who not only rules over the Muslim community with justice but also is able to keep and interpret the divine law (sharīʿa) and its esoteric meaning.

After the death or Occultation of Muhammad ibn Imam Ismāʿīl in the 8th century CE, the teachings of Ismāʿīlīsm further transformed into the belief system as it is known today, with an explicit concentration on the deeper, esoteric meaning (bāṭin) of the Islamic faith.

Another Shia Imami Ismāʿīlī community are the Dawudi Bohras, led by a Da'i al-Mutlaq ("Unrestricted Missionary") as representative of a hidden Imam.

In recent centuries, Ismāʿīlīs have largely been an Indo-Iranian community,[146] but they can also be found in India, Pakistan, Syria, Palestine, Saudi Arabia,[147] Yemen, Jordan, Uzbekistan, Tajikistan, Afghanistan, East and South Africa, and in recent years several Ismāʿīlīs have emigrated to China,[148] Western Europe (primarily in the United Kingdom), Australia, New Zealand, and North America.

Historically, Zaydīs held that Zayd ibn ʿAlī was the rightful successor of the 4th Imam since he led a rebellion against the Umayyads in protest of their tyranny and corruption.

Muhammad al-Baqir did not engage in political action, and the followers of Zayd ibn ʿAlī maintained that a true Imam must fight against corrupt rulers.

In matters of Islamic jurisprudence, Zaydīs follow the teachings of Zayd ibn ʿAlī, which are documented in his book Majmu'l Fiqh (in Arabic: مجموع الفِقه).

"[191] In 1802, the Al Saud-Wahhabi armies of the Ikhwan from the First Saudi State (1727–1818) attacked and sacked the city of Karbala, the Shia shrine in Najaf (eastern region of Iraq) that commemorates the martyrdom and death of Ḥusayn ibn ʿAlī.
