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.
Zayd ibn AliZayd ibn ʿAlī (زيد بن علي; 695–740), 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.

Twelver Shi'ismTwelver Shīʿism (ٱثْنَا عَشَرِيَّة; DIN), also known as Imāmiyya (إِمَامِيَّة), is the largest branch of Shīʿa Islam, comprising about 85 percent of all Shīʿa Muslims. The term Twelver refers to its adherents' belief in twelve divinely ordained leaders, known as the Twelve Imams, and their belief that the last Imam, Imam al-Mahdi, lives in Occultation and will reappear as the promised Mahdi (المهدي المنتظر). Twelvers believe that the Twelve Imams are the spiritual and political successors to the Islamic prophet Muhammad.
Rashidun CaliphateThe Rashidun Caliphate (al-Khilāfah ar-Rāšidah; 632 661) was the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE (11 AH). During its existence, the empire was the most powerful economic, cultural, and military force in West Asia. The caliphate arose following Muhammad’s passing in June 632 and the subsequent debate over the succession to his leadership.
HashemitesThe Hashemites (al-Hāshimiyyūn), 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 were given the thrones of the Hejaz, Syria, Iraq, and Jordan following their World War I alliance with the British Empire; this arrangement became known as the "Sharifian solution".

The other three schools of Sunnī jurisprudence are Ḥanafī, Mālikī and Ḥanbalī. Like the other schools of fiqh, Shafii 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.
