IslamIslam (ˈɪslɑːm; ۘالِإسْلَام, al-ʾIslām ʔɪsˈlæːm, ) is an Abrahamic monotheistic religion centered on the Quran and the teachings of Muhammad. Adherents of Islam, called Muslims, number approximately 2 billion globally and are the world's second-largest religious population after Christians. Muslims believe that Islam is the complete and universal version of a primordial faith that was revealed many times through earlier prophets such as Adam (believed to be the first man), Ibrahim, Moses, and Isa (Jesus), among others.
ZaydismZaydism (الزَّيْدِيَّة) is a branch of Shia Islam that emerged in the eighth century following Zayd ibn Ali‘s unsuccessful rebellion against the Umayyad Caliphate. In contrast to other Shia Muslims of Twelver Shi'ism and Isma'ilism, Zaydis, also sometimes incorrectly called Fivers, consider Zayd to be the Imam to whom obedience is obligatory, due to him being a patrilinial descendent of Fatima and making the Call (Dawah) to jihad, two necessary qualities for an Imam of Obedience for the Zaydis.
AlidsThe Alids are those who claim descent from Ali ibn Abi Talib (عَلِيّ بْن أَبِي طَالِب; 600–661 CE), the fourth Rashidun caliph (656-661) 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.
Islamic schools and branchesIslamic 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 Islamic groups themselves there may be differences, such as different orders (tariqa) within Sufism, and within Sunnī Islam different schools of theology (Atharī, Ashʿarī, Māturīdī) and jurisprudence (Ḥanafī, Mālikī, Shāfiʿī, Ḥanbalī).
AlevismAlevism, Anatolian Alevism or Qizilbashism (æˈlɛvɪzəm; Alevilik, Anadolu Aleviliği or Kızılbaşlık; Elewîtî, Rêya Heqî; Ələvilik, Qızılbaşlıq) is a heterodox Islamic tradition, whose adherents follow the mystical Islamic teachings of Haji Bektash Veli, who is supposed to have taught the teachings of the Twelve Imams. Differing from Sunni Islam and Usuli Twelver Shia Islam, Alevis have no binding religious dogmas, and teachings are passed on by a spiritual leader as with Sufi orders.
Ahl al-BaytAhl al-Bayt (أَهْل ٱلْبَيْت, people of the house) refers to the family of the Islamic prophet Muhammad, but the term has also been extended in Sunni Islam to all descendants of the Banu Hashim (Muhammad's clan) and even to all Muslims. In Shia Islam, the term is limited to Muhammad, his daughter Fatima, his cousin and son-in-law Ali ibn Abi Talib, and their two sons, Ḥasan and Husayn. A common Sunni view adds the wives of Muhammad to these five.
KufaKufa (الْكُوفَة ), also spelled Kufah, is a city in Iraq, about south of Baghdad, and northeast of Najaf. It is located on the banks of the Euphrates River. The estimated population in 2003 was 110,000. Currently, Kufa and Najaf are joined into a single urban area that is mostly commonly known to the outside world as 'Najaf'. Along with Samarra, Karbala, Kadhimiya and Najaf, Kufa is one of five Iraqi cities that are of great importance to Shi'ite Muslims.
SayyidSayyid (UKsaɪɪd,_ˈseɪjɪd, USˈsɑːjɪd; سيد ˈsæjjɪd; sejˈjed; meaning 'sir', 'Lord', 'Master'; Arabic plural: سادة sādah; feminine: سيدة ALA; sejˈjede) is an honorific surname of Muslims recognized as descendants of the Islamic prophet Muhammad through his grandsons, Hasan ibn Ali and Husayn ibn Ali, sons of Muhammad's daughter Fatima and his cousin and son-in-law Ali (Ali ibn Abi Talib). A few Arabic language experts state that it has its roots in the word al-asad الأسد, meaning "lion", probably because of the qualities of valour and leadership.
Succession to MuhammadThe succession to Muhammad is the central issue that split the Muslim community into several divisions in the first century of Islamic history, with the most prominent among these sects being the Shia and Sunni branches of Islam. Sunni Islam maintains that Abu Bakr was the legitimate successor to Muhammad on the basis of election. Shia Islam holds that Ali ibn Abi Talib was the designated successor to the Islamic prophet Muhammad.
KaysanitesThe Kaysanites (Kaysāniyya) were a Shi'i sect of Islam that formed from the followers of Al-Mukhtar. They traced Imamate from Muhammad ibn al-Hanafiyyah and his descendants. The name Kaysaniyya was most likely derived from the name of Mukhtar's chief guard, Abu Amra Kaysan. The followers of Al-Mukhtar who emerged from his movement (including all subsequent sub-sects which evolved from his movement) who firstly upheld the Imamate of Muhammad ibn al-Hanafiyyah and his descendants or any other designated successors were initially named the "Mukhtariyya" (after Al-Mukhtar), but were soon more commonly referred to as the "Kaysānīyya" (i.
