Shia Islam in the context of "Ja'fari"

Sufi philosophy includes the schools of thought unique to Sufism, the mystical tradition within Islam, also termed as Tasawwuf or Faqr according to its adherents. Sufism and its philosophical tradition may be associated with both Sunni and Shia branches of Islam. It has been suggested that Sufi thought emerged from the Middle East in the eighth century CE, but adherents are now found around the world.

According to Sufi Muslims, it is a part of the Islamic teaching that deals with the purification of inner self and is the way which removes all the veils between the divine and humankind. It was around 1000 CE that early Sufi literature, in the form of manuals, treatises, discourses and poetry, became the source of Sufi thinking and meditations. Sufi philosophy, like all other major philosophical traditions, has several sub-branches, including cosmology and metaphysics, as well as several unique concepts.

The issue of succession following the death of the Islamic prophet Muhammad is the central issue in the schisms that divided the early Muslim community in the first century of Islamic history into numerous schools and branches. The two most prominent branches that emerged from these divisions are Sunni and Shia as well as Ibadi branches of Islam. Sunni Islam and Ibadi Islam asserts that Abu Bakr rightfully succeeded Muhammad through a process of election. In contrast, Shia Islam maintains that Ali ibn Abi Talib was Muhammad's designated successor.

These differing viewpoints on succession stem from varying interpretations of early Islamic history and the hadiths, which are the recorded sayings of Muhammad. Sunni Muslims contend that Muhammad did not explicitly appoint a successor, leaving the choice of leadership to the Muslim community. They recognize the legitimacy of Abu Bakr's rule, who was elected at Saqifah, as well as that of his successors, collectively known as the Rashidun caliphs.

Religious conversion is the adoption of a set of beliefs identified with one particular religious denomination to the exclusion of others. Thus "religious conversion" would describe the abandoning of adherence to one denomination and affiliating with another. This might be from one to another denomination within the same religion, for example, from Protestant Christianity to Roman Catholicism or from Shi'a Islam to Sunni Islam. In some cases, religious conversion "marks a transformation of religious identity and is symbolized by special rituals".

People convert to a different religion for various reasons, including active conversion by free choice due to a change in beliefs, secondary conversion, deathbed conversion, conversion for convenience, marital conversion, and forced conversion. Religious conversion can also be driven by practical considerations. Historically, people have converted to evade taxes, to escape military service or to gain political representation.

Kurds (Kurdish: کورد, romanized: Kurd), or the Kurdish people, are an Iranic ethnic group from West Asia. They are indigenous to Kurdistan, which is a geographic region spanning southeastern Turkey, northwestern Iran, northern Iraq, and northeastern Syria. Consisting of 30–45 million people, the global Kurdish population is largely concentrated in Kurdistan, but significant communities of the Kurdish diaspora exist in parts of West Asia beyond Kurdistan and in parts of Europe, most notably including: Turkey's Central Anatolian Kurds, as well as Istanbul Kurds; Iran's Khorasani Kurds; the Caucasian Kurds, primarily in Azerbaijan and Armenia; and the Kurdish populations in various European countries, namely Germany, France, Sweden, and the Netherlands.

The Kurdish languages and the Zaza–Gorani languages, both of which belong to the Western Iranic branch of the Iranic language family, are the native languages of the Kurdish people. Other widely spoken languages among the community are those of their host countries or neighbouring regions, such as Turkish, Persian, or Arabic. The most prevalent religion among Kurds is Sunni Islam, with Shia Islam and Alevism being significant Islamic minorities. Yazidism, which is the ethnic religion of the Kurdish-speaking Yazidi people, is the largest non-Islamic minority religion among the broader Kurdish community, followed by Yarsanism, Zoroastrianism, and Christianity.

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).

Twelver Shi'ism (Arabic: اِثْنَا عَشَرِيَّة, romanized: Ithnā ʿAshariyya) is the largest branch of Shia Islam, comprising about 85% of all Shia Muslims. The term Twelver refers to its adherents' belief in the twelve successors, referred to as Twelve Imams, and their belief that the last Imam, Muhammad al-Mahdi, lives in occultation (ghayba) and will reappear as "the awaited Mahdi" (al-Mahdi al-muntazar) alongside Isa al-Masih (Jesus Christ), son of Bibi Mariam (The Virgin Mary), in order to restore justice and peace.

Twelver Shi'as believe that the Twelve Imams are divinely appointed as both spiritual and political successors to the Islamic prophet Muhammad, and that they possess special knowledge and authority to guide the Muslim community. According to Twelver theology, the Twelve Imams are exemplary human individuals who rule over the Muslim community (Ummah) with justice, and are able to preserve and interpret the Islamic law (Sharia) and the esoteric meaning of the Qur'an. The words and deeds (sunnah) of Muhammad and the Imams are a guide and model for the Muslim community to follow. As a result, Muhammad and the Imams must be free from error and sin, a doctrine known as Ismah (literally 'protection') or infallibility, and must be chosen by divine decree, or nass, through Muhammad.

A confessional state is a state which officially recognises and practices a particular religion (also known as a state religion), usually accompanied by a public cult, ranging from having its citizens incentivised to do likewise through government endorsement to having public spending on the maintenance of church property and clergy be unrestricted, but it does not need to be under the legislative control of the clergy as it would be in a theocracy.

Over human history, many states have been confessional states. This is especially true in countries where Islam, Christianity, and Buddhism were the religions of the state. Until the beginning of the 20th century, many if not most nations had state religions enshrined in their respective constitutions or by decree of the monarch, even if other religions were permitted to practice.

A religious denomination is a subgroup within a religion that operates under a common name and tradition, among other activities.The term refers to the various Christian denominations (for example, non-Chalcedonian, Eastern Orthodox, Catholic, and the branches of Protestantism, such as Lutheranism). It is also used to describe the five major branches of Judaism (Karaite Judaism, Orthodox, Conservative, Reform, and Reconstructionist). Within Islam, it can refer to the branches or sects (such as Sunni and Shia), as well as their various subdivisions, such as sub-sects, schools of jurisprudence, schools of theology and religious movements.

The world's largest religious denomination is the Sunni Islam.

The Saqifa (Arabic: سَقِيفَة, romanized: Saqīfah) of the Banu Sa'ida clan refers to the location of an event in early Islam where some of the companions of the Islamic prophet Muhammad pledged their allegiance to Abu Bakr as the first caliph and successor to Muhammad shortly after his death in 11 AH (632 CE). The Saqifa meeting is among the most controversial events in early Islam, due to the exclusion of a large number of Muhammad's companions, including his immediate family and notably Ali, his cousin and son-in-law. The conflicts that arose soon after Muhammad's death are considered to be the main cause of the current division among Muslims. Those who accepted Abu Bakr's caliphate were later labeled Sunnis, while the supporters of Ali's right to caliphate were later labeled Shia.

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.

From 613 to 619 CE, the Islamic prophet Muhammad gathered in his hometown of Mecca a small following of those who embraced his message of Islam and thus became Muslims. The first person who professed Islam was his wife, Khadija bint Khuwaylid. The identity of the second male Muslim, after Muhammad himself, is disputed largely along sectarian lines, as Shia and some Sunni sources identify him as the first Shia imam Ali ibn Abi Talib, a child at the time, who grew up in the household of his cousin, Muhammad. Other sources report that the first male convert was Abu Bakr, who later succeeded Muhammad as the first Sunni caliph, or Muhammad's foster son, Zayd ibn Haritha. While it is difficult to establish the chronological order of early conversions, the identities of early Muslims are known with some certainty.

The Five Pillars of Islam (arkān al-Islām أركان الإسلام; also arkān ad-dīn أركان الدين "pillars of the religion") are fundamental practices in Islam, particularly Sunni Islam, considered to be obligatory acts of worship for all Muslims. They are summarized in the hadith of Gabriel. The Sunni and Shia agree on the basic details of the performance and practice of these acts, but Shia denominations may have their own lists of pillars that differ from the Sunni five, such as the Twelver Ancillaries of the Faith (consisting of four pillars and six obligatory acts) and the Ismaili Seven Pillars. The five pillars are: profession of faith (Shahada), prayer (Salah), almsgiving (Zakat), fasting in the month of Ramadan (Sawm), and pilgrimage to Mecca (Hajj).

The Shahada (Arabic: الشَّهَادَةُ aš-šahādatu; Arabic pronunciation: [aʃʃahaːdatʊ], 'the testimony'), also transliterated as Shahadah, is an Islamic oath and creed, and one of the Five Pillars of Islam and part of the Adhan. It reads: "I bear witness that there is no god but God, and I bear witness that Muhammad is the Messenger of God."The Shahada declares belief in the oneness (tawhid) of God and the acceptance of Muhammad as God's messenger. Some Shia Muslims also include a statement of belief in the wilayat of Ali, but they do not consider it as an obligatory part for converting to Islam. A single honest recitation of the Shahada is all that is required for a person to become a Muslim according to most traditional schools.

Salah (Arabic: ٱلصَّلَاةُ, romanized: aṣ-Ṣalāh, also spelled Salat), also known as Namaz (Persian: نماز, romanized: namāz), is the practice of formal worship in Islam, consisting of a series of ritual prayers performed at prescribed times daily. These prayers, which consist of units known as rak'ah, include a specific set of physical postures, recitation from the Quran, and prayers from the Sunnah, and are performed while facing the direction towards the Kaaba in Mecca (qibla). The number of rak'ah varies depending on the specific prayer. Variations in practice are observed among adherents of different madhahib (schools of Islamic jurisprudence). The term salah may denote worship in general or specifically refer to the obligatory prayers performed by Muslims five times daily, or, in some traditions, three times daily.

The obligatory prayers play an integral role in the Islamic faith, and are regarded as the second and most important, after shahadah, of the Five Pillars of Islam for Sunnis, and one of the Ancillaries of the Faith for Shiites. In addition, supererogatory salah, such as Sunnah prayer and Nafl prayer, may be performed at any time, subject to certain restrictions. Wudu, an act of ritual purification, is required prior to performing salah. Prayers may be conducted individually or in congregation, with certain prayers, such as the Friday and Eid prayers, requiring a collective setting and a khutbah (sermon). Some concessions are made for Muslims who are physically unable to perform the salah in its original form, or are travelling.

Eid al-Fitr (Arabic: عيد الفطر, romanized: ʿĪd al-Fiṭr, lit. 'Festival of Breaking the Fast') is the first of the two main festivals in Islam, the other being Eid al-Adha. It falls on the first day of Shawwal, the tenth month of the Islamic calendar. Eid al-Fitr is celebrated by Muslims worldwide as it marks the end of the month-long, dawn-to-dusk fasting (sawm) during Ramadan. The holiday is known under various other names in different languages and countries around the world.

Eid al-Fitr has a particular salah that consists of two rakats generally performed in an open field or large hall. It may only be performed in congregation (jamāʿat) and features six additional Takbirs (raising of the hands to the ears whilst reciting the Takbir, saying "Allāhu ʾAkbar", meaning "God is the greatest"). In the Hanafi school of Sunni Islam, there are three Takbirs at the start of the first rakat and three just before rukūʿ in the second rakat. Other Sunni schools usually have 12 Takbirs, similarly split in groups of seven and five. In Shia Islam, the salat has six Takbirs in the first rakat at the end of Tilawa, before rukūʿ, and five in the second. Depending on the juristic opinion of the locality, this salat is either farḍ (فرض, obligatory) or mustaḥabb (strongly recommended). After the salat, Muslims celebrate the Eid al-Fitr in various ways with food being a central theme, which also gives the holiday the nickname "Sweet Eid" or "Sugar Feast".

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).

Khalifa or Khalifah (Arabic: خليفة, romanized: Khalīfa; commonly "caliph" in English) is a name or title which means "successor", "ruler" or "leader". It most commonly refers to the leader of a Caliphate, but can also be used as a title among various Islamic religious groups and others. There were four Rashidun caliphs after Muhammad died, beginning with Abu Bakr. The Khilafah (or Caliphate) was then contested and gave rise to the eventual division of the Islamic Umma into two groups, the Sunni and the Shi'a who interpret the word Khalifa in differently nuanced ways.

The earliest Islamic uses include 'Khaleefa(ḥ)' in The Qur'an, 2:30, where God commands the angels to bow down to Adam) with reverence. "Vicegerent", therefore, is more at "divinely-guided spokesman" than "deputy" in this context and leads to the discovery of the role of Imam in Islam, from the Shi'i or Shi'a point of view where, it is claimed, the spiritual Khilaafat or designation of Khaleefa in this meaning of spiritual and temporal guide falls upon the first Imam, 'Ali ibn Abi Talib, (who received his mission from his cousin Muhammed and who also conceded the Khilaafat to the election and claim of the politically more powerful and more popular leader and his senior, Abu Bakr). In the Shi'i tradition, the dissolved claim to the Khilaafat by Shi'i thereafter crystallised into Imamat which continued with his descendants after him through appointment by nass, or designation.

Fakir, faqeer, or faqīr (/fəˈkɪər/; Arabic: فقیر (noun of faqr)), derived from faqr (Arabic: فقر, 'poverty'), is an Islamic term traditionally used for Sufi Muslim ascetics who renounce their worldly possessions and dedicate their lives to the worship of God. They do not necessarily renounce all relationships, or take vows of poverty, but the adornments of the temporal worldly life are kept in perspective. The connotations of poverty associated with the term relate to their spiritual neediness, not necessarily their physical neediness, which they adopt to seek purity and mystical knowledge and so earn God's love.

They are characterized by their reverence for dhikr (a devotional practice which consists of repeating the names of God with various formulas, often performed after the daily prayers). Sufism in the Muslim world emerged during the early Umayyad Caliphate (661–750 CE) and grew as a mystic tradition in the mainstream Sunni and Shia denominations of Islam, which according to Eric Hanson and Karen Armstrong was likely in reaction to "the growing worldliness of Umayyad and Abassid societies". Sufi Muslim ascetics (fakirs and dervishes) were highly influential and greatly successful in spreading Islam between the 10th and 19th centuries, particularly to the furthest outposts of the Muslim world in the Middle East and North Africa, the Balkans and Caucasus, the Indian subcontinent, and finally Central, Eastern, and Southeast Asia. Sufi Muslims have spread throughout several continents and cultures over a millennium, originally expressing their beliefs in Arabic, before spreading into Persian, Turkish, Indian languages, and a dozen other languages.
