Abd Allah ibn Abi Quhafa, commonly known by the kunyaAbu Bakr, was the first caliph, ruling from 632 until his death in 634. A close companion and father-in-law of Muhammad, Abu Bakr is referred to with the honorific title al-Ṣiddīq by Sunni Muslims.
Shia Islam is the second-largest branch of Islam. It holds that the Islamic prophet Muhammad designated Ali ibn Abi Talib (656–661 CE) as his successor as Imam, most notably at the event of Ghadir Khumm, but that after Muhammad's death, Ali was prevented from succeeding as leader of the Muslims as a result of the choice made by some of Muhammad's other companions at Saqifah. This view primarily contrasts with that of Sunni Islam, whose adherents believe that Muhammad did not appoint a successor before his death and consider Abu Bakr, who was appointed caliph by a group of Muhammad's other companions at Saqifah, to be the first Rashidun ('rightful') caliph after Muhammad (632–634 CE).
The Hashemites, also House of Hashim, are the royal family of Jordan, which they have ruled since 1921, and were the royal family of the kingdoms of Hejaz (1916–1925), Syria (1920), and Iraq (1921–1958). The family had ruled the city of Mecca continuously from the 10th century, frequently as vassals of outside powers, and ruled the thrones of the Hejaz, Syria, Iraq, and Jordan following their World War I alliance with the British Empire.
Colonel General Ali Hassan Majid al-Tikriti, was an Iraqi military officer and politician under Saddam Hussein who served as Defense minister, Interior minister, and chief of the General Security. He was also the governor of Kuwait during much of the 1990–91 Gulf War.
Husayn ibn Ali was a social, political and religious leader. The grandson of the Islamic prophet Muhammad and a son of Ali ibn Abi Talib and Muhammad's daughter Fatima, as well as a younger brother of Hasan ibn Ali, Husayn is regarded as the third Imam (leader) in Shia Islam after his brother, Hasan, and before his son, Ali al-Sajjad. Being the grandson of the prophet, he is also a prominent member of the Ahl al-Bayt. He is also considered to be a member of the Ahl al-Kisa, and a participant in the event of the mubahala. Muhammad described him and his brother, Hasan, as the leaders of the youth of Paradise.
Ali ibn Abi Talib was the cousin and son-in-law of the Islamic prophet Muhammad, and was the fourth Rashidun caliph who ruled from 656 CE to 661, as well as the first Shia imam. Born to Abu Talib ibn Abd al-Muttalib and Fatima bint Asad, young Ali was raised by his elder cousin Muhammad and was among the first to accept his teachings.
Hasan ibn Ali was an Alid political and religious leader. The eldest son of Ali and Fatima and a grandson of the Islamic prophet Muhammad, Hasan briefly ruled as Rashidun caliph from January 661 until August 661. He is considered as the second Imam in Shia Islam, succeeding Ali and preceding his brother Husayn. As a grandson of the prophet, he is part of the ahl al-bayt and the ahl al-kisa, and also participated in the event of the mubahala.
In Shia Islam, the Imamah is a doctrine which asserts that certain individuals from the lineage of the Islamic prophet Muhammad are to be accepted as leaders and guides of the ummah after the death of Muhammad. Imamah further says that Imams possess divine knowledge and authority (Ismah) as well as being part of the Ahl al-Bayt, the family of Muhammad. These Imams have the role of providing commentary and interpretation of the Quran as well as guidance.
Zayd ibn ʿAlī, also spelled Zaid, was the son of Ali ibn al-Husayn Zayn al-Abidin, and great-grandson of Ali ibn Abi Talib. He led an unsuccessful revolt against the Umayyad Caliphate, in which he died. The event gave rise to the Zaydiyya sect of Shia Islam, which holds him as the next Imam after his father Ali ibn al-Husayn Zayn al-Abidin. Zayd ibn Ali is also seen as a major religious figure by many Sunnis and was supported by the prominent Sunni jurist, Abu Hanifa, who issued a fatwa in support of Zayd against the Umayyads.
Zaydism is one of the three main branches of Shia Islam that emerged in the eighth century following Zayd ibn Ali's unsuccessful rebellion against the Umayyad Caliphate. Zaydism is typically considered to be a branch of Shia Islam that comes closest to the Sunni, although the "classical" form of Zaydism over the centuries had changed its posture with regard to Sunni and Shia traditions multiple times, to the point where interpretation of Zaydi as Shia is often based on just their acceptance of Ali as a rightful successor to the Islamic prophet Muhammad. Mainstream ("twelver") Shia sometimes consider Zaydism to be a "fifth school" of Sunni Islam. Zaydis regard rationalism as more important than Quranic literalism and in the past were quite tolerant towards Sunni Shafi'ism, a religion of about half of the Yemenis.
Alawites are an esoteric Arab ethnoreligious group who live primarily in the Levant region in West Asia and follow Alawism, an esoteric sect of Islam that splintered from early Shia as a ghulat branch during the ninth century. Alawites venerate Ali ibn Abi Talib, the "first Imam" in the Twelver school, as the physical manifestation of God. The group was founded by Ibn Nusayr during the 9th century. Ibn Nusayr 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.
Sayyid is an honorific title of Hasanids and Husaynids Muslims, recognized as descendants of the Islamic prophet's companion, Ali through his grandsons, Hasan and Husayn.
A caliphate is an institution or public office under the leadership of an Islamic steward with the title of caliph, a person considered a political–religious successor to the Islamic prophet Muhammad and a leader of the entire Muslim world (ummah). Historically, the caliphates were polities based on Islam which developed into multi-ethnic trans-national empires.
Abu al-Hasan Ali ibn Uthman al-Jullabi al-Hujwiri, known reverentially as Data Sahib, was an Islamic scholar and mystic who authored Kashf al-Mahjub, the earliest treatise on Sufism in the Persian language. Born in the Ghaznavid Empire, al-Hujwiri is believed to have contributed "significantly" to the spread of Islam in South Asia through his preaching.
The Alids are those who claim descent from Ali ibn Abi Talib, the fourth Rashidun caliph and the first imam in Shia Islam. Ali was also the cousin and son-in-law of the Islamic prophet Muhammad. The main branches are the Hasanids and Husaynids, named after Hasan and Husayn, the eldest sons of Ali from his marriage to Fatima, the daughter of Muhammad. As the progeny of Muhammad, they are revered by all Muslims. The Alids have led various movements in Islam, and a line of twelve Alids are the imams in Twelver Shia, the largest Shia branch.
Ali ibn al-Husayn al-Sajjad, also known as Zayn al-Abidin was the great-grandson of the Islamic prophet Muhammad, and the fourth imam in Shia Islam, succeeding his father, Husayn ibn Ali, his uncle, Hasan ibn Ali, and his grandfather, Ali ibn Abi Talib.
Ahl al-Bayt refers to the family of the Islamic prophet Muhammad. In Sunni Islam, the term has also been extended to all descendants of the Banu Hashim and even to all Muslims. In Shia Islam, the term is limited to Muhammad, his daughter Fatima, his cousin and son-in-law Ali, and their two sons, Ḥasan and Ḥusayn. A common Sunni view adds the wives of Muhammad to these five.
The Battle of Siffin was fought in 657 CE between the fourth Rashidun caliph Ali ibn Abi Talib and the rebellious governor of Syria Mu'awiya ibn Abi Sufyan. The battle is named after its location Siffin on the banks of the Euphrates. The fighting stopped after the Syrians called for arbitration to escape defeat, to which Ali agreed under pressure from some of his troops. The arbitration process ended inconclusively in 658 though it strengthened the Syrians' support for Mu'awiya and weakened the position of Ali. The battle is considered part of the First Fitna and a major step towards the establishment of the Umayyad Caliphate.
The holiest sites in Islam are located in the Arabian Peninsula. 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 two cities as having the highest degree of holiness, in descending order: Mecca, and Medina. Mecca's Al-Masjid al-Haram, and Al-Masjid an-Nabawi in Medina are all revered by Muslims as sites of great importance.
Fatima bint Muhammad, commonly known as Fatima al-Zahra', was the daughter of the Islamic prophet Muhammad and his wife Khadija. Fatima's husband was Ali, the fourth of the Rashidun Caliphs and the first Shia Imam. Fatima's sons were Hasan and Husayn, the second and third Shia Imams, respectively. Fatima has been compared to Mary, mother of Jesus, especially in Shia Islam. Muhammad is said to have regarded her as the best of women and the dearest person to him. She is often viewed as an ultimate archetype for Muslim women and an example of compassion, generosity, and enduring suffering. It is through Fatima that Muhammad's family line has survived to this date. Her name and her epithets remain popular choices for Muslim girls.
