Rashidun in the context of "Shi'a Islam"

Sunni Islam is the largest branch of Islam and the largest religious denomination in the world. It holds that Muhammad did not appoint any successor and that his closest companion Abu Bakr (r. 632–634) rightfully succeeded him as the caliph of the Muslim community, being appointed at the meeting of Saqifa. This contrasts with the Shia view, which holds that Muhammad appointed Ali ibn Abi Talib (r. 656–661) as his successor. Nevertheless, Sunnis revere Ali, along with Abu Bakr, Umar (r. 634–644) and Uthman (r. 644–656) as 'rightly-guided caliphs'.

The term Sunni means those who observe the sunna, the practices of Muhammad. The Quran, together with hadith (especially the Six Books) and ijma (scholarly consensus), form the basis of all traditional jurisprudence within Sunni Islam. Sharia legal rulings are derived from these basic sources, in conjunction with consideration of public welfare and juristic discretion, using the principles of jurisprudence developed by the four legal schools: Hanafi, Hanbali, Maliki and Shafi'i.

The Rashidun Caliphate (Arabic: ٱلْخِلَافَةُ ٱلرَّاشِدَةُ, romanized: al-Khilāfah ar-Rāšidah) is the early Islamic polity led by the first four successive caliphs (lit. "successors") Abu Bakr, Umar, Uthman and Ali, collectively the Rashidun, or "Rightly Guided" caliphs. These early caliphs led the Muslim community from the death of the Islamic prophet Muhammad in 632 CE to the foundation of the Umayyad Caliphate in 661 CE.

The title Rashidun stems from the Sunni Islamic belief that the caliphs were "rightly guided". Endowed with superior piety and wisdom, their era is regarded in Sunni Islam as a "golden age", second only to the lifetime of the Prophet Muhammad in sanctity and in providing moral and religious guidance. Sunni Muslims consider the "rightly guided" reign of the first four caliphs as a model to be followed and emulated from a religious point of view. The term Rashidun is not used by Shia Muslims, who make up 10–15% of the global Muslim population, as they reject the rule of the first three caliphs as illegitimate.

The spread of Islam spans almost 1,400 years. The early Muslim conquests that occurred following the death of Muhammad in 632 CE led to the creation of the caliphates, expanding over a vast geographical area; conversion to Islam was boosted by Arab Muslim forces expanding over vast territories and building imperial structures over time. Most of the significant expansion occurred during the reign of the rāshidūn ("rightly-guided") caliphs from 632 to 661 CE, which were the first four successors of Muhammad. These early caliphates, coupled with Muslim economics and trading, the Islamic Golden Age, and the age of the Islamic gunpowder empires, resulted in Islam's spread outwards from Mecca towards the Indian, Atlantic, and Pacific Oceans and the creation of the Muslim world. The Islamic conquests, which culminated in the Arab empire being established across three continents (Asia, Africa, and Europe), enriched the Muslim world, achieving the economic preconditions for the emergence of this institution owing to the emphasis attached to Islamic teachings. Trade played an important role in the spread of Islam in some parts of the world, such as Indonesia. During the early centuries of Islamic rule, conversions in the Middle East were mainly individual or small-scale. While mass conversions were favored for spreading Islam beyond Muslim lands, policies within Muslim territories typically aimed for individual conversions to weaken non-Muslim communities. However, there were exceptions, like the forced mass conversion of the Samaritans.

Muslim dynasties were soon established and subsequent empires such as those of the Umayyads, Abbasids, Mamluks, Seljukids, and the Ayyubids were among some of the largest and most powerful in the world. The Ajuran and Adal Sultanates, and the wealthy Mali Empire, in North Africa, the Delhi, Deccan, and Bengal Sultanates, and Mughal and Durrani Empires, and Kingdom of Mysore and Nizam of Hyderabad in the Indian subcontinent, the Ghaznavids, Ghurids, Samanids in Persia, Timurids, and the Ottoman Empire in Anatolia significantly changed the course of history. The people of the Islamic world created numerous sophisticated centers of culture and science with far-reaching mercantile networks, travelers, scientists, hunters, mathematicians, physicians, and philosophers, all contributing to the Islamic Golden Age. The Timurid Renaissance and the Islamic expansion in South and East Asia fostered cosmopolitan and eclectic Muslim cultures in the Indian subcontinent, Malaysia, Indonesia and China. The Ottoman Empire, which controlled much of the Middle East and North Africa in the early modern period, also did not officially endorse mass conversions, but evidence suggests they occurred, particularly in the Balkans, often to evade the jizya tax. Similarly, Christian sources mention requests for mass conversions to Islam, such as in Cyprus, where Ottoman authorities refused, fearing economic repercussions.

The Muslim conquest of the Levant (Arabic: فَتْحُ الشَّام, romanized: Fatḥ al-šām; lit. 'Conquest of Syria'), or Arab conquest of Syria, was a 634–638 CE conquest of Byzantine Syria by the Rashidun Caliphate.

A part of the wider Arab–Byzantine wars, the Levant was brought under Arab Muslim rule and developed into the provincial region of Bilad al-Sham. Clashes between the Arabs and Byzantines on the southern Levantine borders of the Byzantine Empire had occurred during the lifetime of Muhammad, with the Battle of Muʿtah in 629 CE. However, the actual conquest did not begin until 634, two years after Muhammad's death. It was led by the first two Rashidun caliphs who succeeded Muhammad: Abu Bakr and Umar ibn al-Khattab. During this time, Khalid ibn al-Walid was the most important leader of the Rashidun army.

Shia Islam is the second-largest branch of Islam. It holds that Muhammad designated Ali ibn Abi Talib (r. 656–661) as both his political successor (caliph) and as the spiritual leader of the Muslim community (imam). However, his right is understood to have been usurped by a number of Muhammad's companions at the meeting of Saqifa, during which they appointed Abu Bakr (r. 632–634) as caliph instead. As such, Sunni Muslims believe Abu Bakr, Umar (r. 634–644), Uthman (r. 644–656) and Ali to be 'rightly-guided caliphs', whereas Shia Muslims regard only Ali as the legitimate successor.

Shia Muslims believe that the imamate continued through Ali's sons, Hasan and Husayn, after which various Shia branches developed and recognized different imams. They revere the ahl al-bayt, the family of Muhammad, maintaining that they possess divine knowledge. Shia holy sites include the shrine of Ali in Najaf, the shrine of Husayn in Karbala, and other mausoleums of the ahl al-bayt. 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.

The Shafi'i school or Shafi'i Madhhab (Arabic: ٱلْمَذْهَب ٱلشَّافِعِيّ, romanized: al-madhhab al-shāfiʿī) or Shafi'i is one of the four major schools of Islamic jurisprudence, belonging to the Ahl al-Hadith tradition within Sunni Islam. It was founded by the Muslim scholar, jurist, and traditionist al-Shafi'i (c. 767–820 CE), "the father of Muslim jurisprudence", in the early 9th century.

The other three schools of Sunnī jurisprudence are Ḥanafī, Mālikī and Ḥanbalī. Like the other schools of fiqh, Shafiʽi recognize the First Four Caliphs as the Islamic prophet Muhammad's rightful successors and relies on the Qurʾān and the "sound" books of Ḥadīths as primary sources of law. The Shafi'i school affirms the authority of both divine law-giving (the Qurʾān and the Sunnah) and human speculation regarding the Law. Where passages of Qurʾān and/or the Ḥadīths are ambiguous, the school seeks guidance of Qiyās (analogical reasoning). The Ijmā' (consensus of scholars or of the community) was "accepted but not stressed". The school rejected the dependence on local traditions as the source of legal precedent and rebuffed the Ahl al-Ra'y (personal opinion) and the Istiḥsān (juristic discretion).

The first Islamic state was established by the Islamic prophet Muhammad in Medina in 622 under the Constitution of Medina. It represented the political unity of the Muslim Ummah (nation). After Muhammad's death, his companions known as the Rightly Guided Caliphs (Rashidun) founded the Rashidun Caliphate (632–661), which began massive expansion and motivated subsequent Islamic states, such as the Umayyad Caliphate (661–750) and Abbasid Caliphate (750–1258).

Muhammad came to the city of Medina following the migration of his followers in what is known as the Hijrah (migration to Medina) in 622. He had been invited to Medina by city leaders to adjudicate disputes between clans from which the city suffered, and was received positively by the city's Jewish and pagan residents as an arbitrator. As a result, he was accepted by popular consensus as the city's political leader, establishing the first Islamic state with his role.

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 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.

The Second Fitna was the second civil war in the Islamic community during the early Umayyad Caliphate. It followed the death of the first Umayyad caliph Mu'awiya I in 680, and lasted for about twelve years. The war involved the defeat of three main challenges to the authority of the Umayyad dynasty, the first by Husayn ibn Ali, as well as his supporters including Sulayman ibn Surad and Mukhtar al-Thaqafi who rallied to avenge his death in Iraq, the second by Abd Allah ibn al-Zubayr who proclaimed himself caliph in Mecca and Medina and would be nominally recognized throughout most of the Caliphate, and the Kharijites who took over central Arabia and southern Iraq and Persia.

The roots of the civil war go back to the First Fitna. After the assassination of the third Rashidun caliph Uthman, the Islamic community experienced its first civil war over the immediate question of retribution for his murder. Following the assassination of the fourth Rashidun caliph Ali in 661 and the abdication of his successor Hasan the same year, Mu'awiya became the sole ruler of the caliphate. Mu'awiya's unprecedented decision to nominate his son Yazid as his heir sparked opposition, and tensions soared after Mu'awiya's death. Husayn ibn Ali was invited by the pro-Alids of Kufa to overthrow the Umayyads but was killed with his small company en route to Kufa at the Battle of Karbala in October 680. Yazid's army suppressed anti-government rebels in Medina in August 683 and subsequently besieged Mecca, where Ibn al-Zubayr had established himself in opposition to Yazid. After Yazid died in November the siege was abandoned, and Umayyad authority would soon collapse throughout the caliphate following the death of his son except in parts of Syria where Marwan I was proclaimed caliph; most provinces recognized Ibn al-Zubayr as caliph. A series of pro-Alid movements demanding to avenge Husayn's death emerged in Kufa, beginning with Ibn Surad's Penitents movement, which was crushed by the Umayyads at the Battle of Ayn al-Warda in January 685. Kufa was then taken over by Mukhtar, who rallied Husayn's supporters and the disenfranchised mawali to his cause. Though his forces routed a large Umayyad army at the Battle of Khazir in August 686, Mukhtar and his supporters were slain by the Zubayrids in April 687 following a series of battles. Under the leadership of Marwan, the Umayyads would consolidate their power over Syria and retake Egypt from the Zubayrids, and under his successor Abd al-Malik ibn Marwan, the Umayyads would reconquer Iraq after defeating the Zubayrids at the Battle of Maskin in 691 and would reassert their control over the Caliphate after killing Ibn al-Zubayr in the second siege of Mecca in 692, while their general Al-Hajjaj ibn Yusuf would suppress the Kharijites in the years afterwards.

Marwan ibn al-Hakam ibn Abi al-As ibn Umayya (Arabic: مروان بن الحكم بن أبي العاص بن أمية, romanized: Marwān ibn al-Ḥakam ibn Abī al-ʿĀṣ ibn Umayya; 623 or 626 – April/May 685), commonly known as Marwan I, was the fourth Umayyad caliph, ruling for less than a year in 684–685. He founded the Marwanid ruling house of the Umayyad dynasty, which replaced the Sufyanid house after its collapse in the Second Fitna and remained in power until 750.

During the reign of his cousin, the third Rashidun caliph Uthman (r. 644–656), Marwan took part in a military campaign against the Byzantine Exarchate of Africa (in central North Africa), where he acquired significant war spoils. He also served as Uthman's governor in Fars (southwestern Iran) before becoming the caliph's katib (secretary or scribe). He was wounded fighting the rebel siege of Uthman's house, in which the caliph was slain. In the ensuing civil war between the fourth Rashidun caliph Ali (r. 656–661) and the largely Qurayshite partisans of Aisha, Marwan sided with the latter at the Battle of the Camel. Marwan later served as governor of Medina under his distant kinsman Caliph Mu'awiya I (r. 661–680), founder of the Umayyad Caliphate. During the reign of Mu'awiya's son and successor Yazid I (r. 680–683), Marwan organized the defense of the Umayyad realm in the Hejaz (western Arabia) against the local opposition which included prominent companions as well as Muhammad’s own clan, the Bani Hashim, who revolted under the banner of Muhammad’s grandson, Husayn ibn Ali. After Yazid died in November 683, the Mecca-based rebel and sahabi Abd Allah ibn al-Zubayr declared himself caliph and expelled Marwan, who took refuge in Syria, the center of Umayyad rule. With the death of the last Sufyanid caliph Mu'awiya II in 684, Marwan, encouraged by the ex-governor of Iraq Ubayd Allah ibn Ziyad, volunteered his candidacy for the caliphate during a summit of pro-Umayyad tribes in Jabiya. The tribal nobility, led by Ibn Bahdal of the Banu Kalb, elected Marwan and together they defeated the pro-Zubayrid Qays tribes at the Battle of Marj Rahit in August of that year.

Al-Marwani (Arabic: ُٱلْمَرْوَنِي, romanized: al-Marwānī) or Banu Marwan (Arabic: بَنِوُ مَرْوَانَ, lit. 'Sons of Marwan'), also referred to as the Marwanids (Arabic: ٱلْمَرْوَنِيُون, romanized: al-Marwāniyūn), is a prominent Arab clan belonging to the Banu Umayya branch of the Quraysh tribe. They are the descendants of Marwan ibn al-Hakam, fourth Umayyad caliph and paternal first cousin of the Rashidun caliph Uthman ibn Affan. Their roots lie in the holy city of Mecca in the Hejaz, the ancestral homeland of the Quraysh tribe, while their historical establishment was in Damascus, Syria. They are considered first cousins of the Banu Hashim, the clan of the Prophet Muhammad, since Umayya ibn Abd Shams ibn Abd Manaf was the paternal nephew of Hashim ibn Abd Manaf. They are also cousins of the Banu Shayba clan of Quraysh, the hereditary custodians of the Kaaba, through Marwan's maternal grandmother al-Sa'ba bint Abi Talha Abd Allah ibn Abd al-Uzza al-Abdariyya, the paternal aunt of Uthman ibn Talha ibn Abd Allah al-Abdari upon whom the Prophet Muhammad entrusted the guardianship of the keys of the Kaaba after the Conquest of Mecca.

The clan arrived in Damascus in the second half of the 7th century CE when Marwan I, the family's progenitor, moved from the Hejaz to Syria. His accession at the tribal conclave of Marj Rahit (684) marked the transfer of the caliphate within the Banu Umayya clan from the family of Abu Sufyan to his family. The family constitutes one of the two principal cadet branches of the Umayyad dynasty, the other being the Sufyanids, descended from Muʿawiya I ibn Abi Sufyan. At their height, the Marwanis represented the dominant branch of the Umayyad family, producing most of its ruling members and remaining the most numerous line of Umayyad descendants in later generations. The family supplied caliphs, princes, governors and commanders in the 7th–11th centuries and continued as a recognizable lineage in the central Islamic lands and in al-Andalus after 750.
