Isma'ilism in the context of "Musta'li"

A madhhab (Arabic: مَذْهَب, romanized: madhhab, lit. 'way to act', IPA: [ˈmaðhab], pl. مَذَاهِب, madhāhib, [ˈmaðaːhib]) refers to any school of thought within Islamic jurisprudence. The major Sunni madhhab are Hanafi, Maliki, Shafi'i and Hanbali. They emerged in the ninth and tenth centuries CE and by the twelfth century almost all Islamic jurists aligned themselves with a particular madhhab. These four schools recognize each other's validity and they have interacted in legal debate over the centuries. Rulings of these schools are followed across the Muslim world without exclusive regional restrictions, but they each came to dominate in different parts of the world. For example, the Maliki school is predominant in North and West Africa; the Hanafi school in South and Central Asia; the Shafi'i school in East Africa and Southeast Asia; and the Hanbali school in North and Central Arabia. The first centuries of Islam also witnessed a number of short-lived Sunni madhhabs. The Zahiri school, which is considered to be endangered, continues to exert influence over legal thought. The development of Shia legal schools occurred along the lines of theological differences and resulted in the formation of the Ja'fari madhhab amongst Twelver Shias, as well as the Isma'ili and Zaydi madhhabs amongst Isma'ilis and Zaydis respectively, whose differences from Sunni legal schools are roughly of the same order as the differences among Sunni schools. The Ibadi legal school, distinct from Sunni and Shia madhhabs, is predominant in Oman. Unlike Sunnis, Shias, and Ibadis, non-denominational Muslims are not affiliated with any madhhab.

The transformations of Islamic legal institutions in the modern era have had profound implications for the madhhab system. With the spread of codified state laws in the Muslim world, the influence of the madhhabs beyond personal ritual practice depends on the status accorded to them within the national legal system. State law codification commonly drew on rulings from multiple madhhabs, and legal professionals trained in modern law schools have largely replaced traditional ulama as interpreters of the resulting laws. In the 20th century, some jurists began to assert their intellectual independence from traditional madhhabs. With the spread of Salafi influence and reformist currents in the 20th century; a handful of Salafi scholars have asserted independence from being strictly bound by the traditional legal mechanisms of the four schools. Nevertheless, the majority of Sunni scholarship continues to uphold post-classical creedal belief in rigorously adhering (Taqlid) to one of the four schools in all legal details.

Islamic schools and branches have different understandings of Islam. There are many different sects or denominations, schools of Islamic jurisprudence, and schools of Islamic theology, or ʿaqīdah (creed). Within Sunnī Islam, there may be differences, such as different orders (tariqa) within Sufism, different schools of theology (Atharī, Ashʿarī, Māturīdī) and jurisprudence (Ḥanafī, Mālikī, Shāfiʿī, Ḥanbalī). Groups in Islam may be numerous (Sunnīs make up 87-90% of all Muslims), or relatively small in size (Ibadis, Ismāʿīlīs, Zaydīs).

Differences between the groups may not be well known to Muslims outside of scholarly circles, or may have induced enough passion to have resulted in political and religious violence (Barelvism, Deobandism, Salafism, Wahhabism). There are informal movements driven by ideas (such as Islamic modernism and Islamism), as well as organized groups with governing bodies (such as Nation of Islam). Some of the Islamic sects and groups regard certain others as deviant or not being truly Muslim (for example, Sunnīs frequently discriminate against Ahmadiyya, Alawites, Quranists, and sometimes Shīʿas). Some Islamic sects and groups date back to the early history of Islam between the 7th and 9th centuries CE (Kharijites, Mu'tazila, Sunnīs, Shīʿas), whereas others have arisen much more recently (Islamic neo-traditionalism, liberalism and progressivism, Islamic modernism, Salafism and Wahhabism), or even in the 20th century (Nation of Islam). Still others were influential historically, but are no longer in existence (non-Ibadi Kharijites and Murji'ah).

The Druze, who call themselves al-Muwaḥḥidūn (lit. 'the monotheists' or 'the unitarians'), are an Arab esoteric religious group from West Asia who adhere to the Druze faith, an Abrahamic, monotheistic, and syncretic religion whose main tenets assert the unity of God, reincarnation, and the eternity of the soul.

Although the Druze faith developed from Isma'ilism, Druze do not identify as Muslims. They maintain the Arabic language and culture as integral parts of their identity, with Arabic being their primary language. Most Druze religious practices are kept secret, and conversion to their religion is not permitted for outsiders. Interfaith marriages are rare and strongly discouraged. They differentiate between spiritual individuals, known as "uqqāl", who hold the faith's secrets, and secular ones, known as "juhhāl", who focus on worldly matters. Druze believe that, after completing the cycle of rebirth through successive reincarnations, the soul reunites with the Cosmic Mind (al-ʻaql al-kullī).

The Encyclopedia of the Epistles of Purity is an esoteric Shia Islamic text written by the mysterious Brethren of Purity during the Buyid era. Composed of 52 treatises, it had a great influence on later intellectual leading lights of the Muslim world, such as Ibn Arabi, and was transmitted as far abroad within the Muslim world as al-Andalus.

The identity and period of the authors of the Encyclopedia have not been conclusively established, though the work has been mostly linked with Isma'ilism. Idris Imad al-Din, a prominent 15th-century Isma'ili missionary in Yemen, credited the authorship of the encyclopedia to Muhammad al-Taqi, the 9th Isma'ili Imam, who lived in occultation in the era of the Abbasid Caliphate at the beginning of the Islamic Golden Age.

The nations which make up Central Asia are five of the former Soviet republics: Kazakhstan, Kyrgyzstan, Turkmenistan, Tajikistan and Uzbekistan, which have a total population of about 76 million. Afghanistan is not always considered part of the region, but when it is, Central Asia has a total population of about 122 million (2016); Mongolia and Xinjiang (part of China) is also sometimes considered part of Central Asia due to its Central Asian cultural ties and traditions, although geographically it is East Asian. Most central Asians belong to religions which were introduced to the area within the last 1,500 years, such as Sunni Islam, Shia Islam, Ismaili Islam, Tengriism and Syriac Christianity (mostly East Syriac). Buddhism, however, was introduced to Central Asia over 2,200 years ago, and Zoroastrianism, over 2,500 years ago.

The Fatimid dynasty (Arabic: الفاطميون, romanized: al-Fāṭimiyyūn) was an Arab dynasty that ruled the Fatimid Caliphate, between 909 and 1171 CE. Descended from Fatima and Ali, and adhering to Isma'ili Shi'ism, they held the Isma'ili imamate, and were regarded as the rightful leaders of the Muslim community. The line of Nizari Isma'ili imams, represented today by the Aga Khans, claims descent from a branch of the Fatimids. The Alavi Bohras, predominantly based in Vadodara, also claim descent from the Fatimids.

The Fatimid dynasty emerged as the leaders of the clandestine early Isma'ili missionary movement (da'wa) in the ninth century CE, ostensibly acting on behalf of a hidden imam, implied at the time to be Muhammad ibn Isma'il. The Isma'ili da'wa spread widely across the Islamic world, then ruled by the Abbasid Caliphate. In 899, the future first Fatimid caliph, Abdallah, proclaimed himself to be the expected imam, causing a rift in the Isma'ili da'wa as the Qarmatians, who did not recognize his imamate, split off. In the meantime, Isma'ili agents had managed to conquer large parts of Yemen and Ifriqiya, as well as launch uprisings in Syria and Iraq. Fleeing Abbasid persecution to Ifriqiya, Abdallah proclaimed himself openly and established the Fatimid Caliphate in 909. From there, the Fatimid imam–caliphs extended their rule over most of the Maghreb as well as Sicily, before conquering Egypt in 969. Founding Cairo as their new capital, for the next two centuries, the Fatimids would be based in Egypt and identified with the country. At their height, the Fatimids claimed control or suzerainty over much of North Africa, Sicily, Egypt, the Levant, the Hejaz, Yemen, and Multan.

Abū Muḥammad ʿAbd Allāh ibn al-Ḥusayn (Arabic: أبو محمد عبد الله بن الحسين; 31 July 874 – 4 March 934), better known by his regnal name al-Mahdī biʾllāh (Arabic: المهدي بالله, "The Rightly Guided by God"), was the founder of the Isma'ili Fatimid Caliphate, the only major Shi'a caliphate in Islamic history, and the eleventh Imam of the Isma'ili branch of Shi'ism.

He was born as Saʿīd ibn al-Ḥusayn (سعيد بن الحسين) in Askar Mukram to a family that led the secret Isma'ili missionary network (da'wa), propagating on behalf of the hidden imam, Muhammad ibn Isma'il, who would return as the prophesied Islamic messiah (mahdi). Orphaned at a young age, he moved to Salamiya, the family's base of operations, where he was adopted by his uncle. In the mid-890s Sa'id succeeded to the leadership of the expanding da'wa, which had expanded and gained adherents across the then Muslim world. However, his claims of not merely being a trustee of the hidden imam, but of him and his ancestors holding the imamate itself, led in 899 to a schism in the Isma'ili movement: those who did not recognise his claims split off to become the Qarmatians. The schism was followed by uprisings of pro-Isma'ili Bedouin in Syria in 902–903, launched without his consent by over-eager supporters, who aimed to force him to come forward as the mahdi. The Bedouin uprising was suppressed by the Abbasids, but drew the attention of the Abbasid Caliphate's authorities to him, forcing him to abandon Salamiya, and flee first to Ramla, then Fustat in Egypt, and finally Sijilmasa in what is now Morocco. There he remained, living as a merchant, until one of his missionaries, Abu Abdallah al-Shi'i, at the head of the Kutama Berbers overthrew the Aghlabid dynasty of Ifriqiya in 909.

Nowruz (Persian: نوروز, Iranian Persian: [noːˈɾuːz], lit. 'New Day') is the Iranian or Persian New Year. Historically, it has been observed by Iranian peoples, but is now celebrated by many ethnicities worldwide. It is a festival based on the Northern Hemisphere spring equinox, which marks the first day of a new year on the Iranian calendars and the currently used Hijri calendar; it usually coincides with a date between 19 March and 22 March on the Gregorian calendar.

The roots of Nowruz lie in Zoroastrianism, and it has been celebrated by many peoples across West Asia, Central Asia, the Caucasus and the Black Sea Basin, the Balkans, and South Asia for over 3,000 years. In the modern era, while it is observed as a secular holiday by most celebrants, Nowruz remains a holy day for Zoroastrians, Baháʼís, and Ismaʿili Shia Muslims.

Nizari Isma'ilis (Arabic: النزارية, romanized: al-Nizāriyya) are the largest segment of the Ismailis, who are the second-largest branch of Shia Islam after the Twelvers. Nizari teachings emphasise the independent legal jurisprudence or ijtihad—though they reject legal reasoning, or usul—pluralism (the acceptance of racial, ethnic, cultural and inter-religious differences) and social justice. Nizaris, along with Twelvers, adhere to the Jaʽfari school of jurisprudence. The Aga Khan, currently Aga Khan V, is the spiritual leader and Imam of the Nizaris. The global seat of the Ismaili Imamate is in Lisbon, Portugal.

The ghulāt (Arabic: غُلَاة, lit. 'exaggerators, extremists') were a branch of early Shi'a Islam. The term mainly refers to a wide variety of extinct Shi'i sects active in 8th- and 9th-century Kufa in Lower Mesopotamia, and who, despite their sometimes significant differences, shared several common ideas. These common ideas included the attribution of a divine nature to the Imams, metempsychosis (the belief that souls can migrate between different human and non-human bodies), a particular gnostic creation myth involving pre-existent 'shadows' (azilla) whose fall from grace produced the material world, and an emphasis on secrecy and dissociation from outsiders. They were named ghulat by other Shi'i and Sunni Muslims for their purportedly "exaggerated" veneration of Muhammad (c. 570–632) and his family, most notably Ali (c. 600–661) and his descendants, the Imams.

The ideas of the ghulat have at times been compared to those of the late antique gnostics, but the extent of this similarity has also been questioned. Some ghulat ideas, such as the notion of the occultation (ghayba) and return (raj'a) of the Imam, have been influential in the development of Twelver Shi'ism. Later Isma'ili Shi'i authors such as Ja'far ibn Mansur al-Yaman (died c. 957) and Abu Ya'qub al-Sijistani (died after 971) also adapted ghulat ideas to reformulate their own doctrines. The only ghulat sect still in existence today are the Alawites, historically known as Nusayris after their founder Ibn Nusayr (died after 868).

Zaydism (Arabic: الزَّيْدِيَّة, romanized: az-Zaydiyya), also referred to as Fiver Shi'ism, is a branch of Shia Islam that emerged in the eighth century following Zayd ibn Ali's unsuccessful rebellion against the Umayyad Caliphate. Zaydism is one of the three main branches of Shi'ism, the other two being Twelverism and Ismailism.

Zaydism is typically considered the Shia branch that is closest to Sunni Islam, although the "classical" form of Zaydism (usually referred to as Hadawi) historically changed its stance on Sunni and Shia traditions multiple times, to the point where Zaydis' simply accepting Ali as a rightful successor to Muhammad was enough to consider them Shia.

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. The Safavid campaign sought to ensure Twelver dominance among Shia Muslims, particularly with regard to Zaydism and Ismaʿilism—each of which had previously experienced their own eras of sectarian dominance.
