Shia Islam

Shia (/ˈʃiːə/; Arabic: شيعة‎ Shīʿah), an abbreviation of Shīʻatu ʻAlī (شيعة علي, "followers of Ali"), is a branch of Islam which holds that the Islamic prophet Muhammad's proper successor as Caliph was his son-in-law and cousin Ali ibn Abi Talib. Shia Islam primarily contrasts with Sunni Islam, whose adherents believe that Muhammad's father-in-law Abu Bakr was his proper successor.

Adherents of Shia Islam are called Shias or the Shi'a as a collective or Shi'i individually. Shia Islam is the second-largest branch of Islam: in 2009, Shia Muslims constituted 10–13% of the world's Muslim population.Twelver Shia (Ithnā'ashariyyah) is the largest branch of Shia Islam. In 2012 it was estimated that perhaps 85 percent of Shias were Twelvers.

Shia Islam is based on the Quran and the message of the Islamic prophet Muhammad attested in hadith recorded by the Shia, and certain books deemed sacred to the Shia (Nahj al-Balagha). Shia consider Ali to have been divinely appointed as the successor to Muhammad, and as the first Imam. The Shia also extend this "Imami" doctrine to Muhammad's family, the Ahl al-Bayt ("the People of the House"), and certain individuals among his descendants, known as Imams, who they believe possess special spiritual and political authority over the community, infallibility, and other divinely-ordained traits. Although there are myriad Shia subsects, modern Shia Islam has been divided into three main groupings: Twelvers, Ismailis and Zaidis, with Twelver Shia being the largest and most influential group among Shia.

Doctrine

Doctrine (from Latin: doctrina) is a codification of beliefs or a bodys, taught principles or positions, as the essence of teachings in a given branch of knowledge or belief system. The Greek analogue is the etymology of catechism.

Often doctrine specifically suggests a body of religious principles as it is promulgated by a church, but not necessarily; doctrine is also used to refer to a principle of law, in the common law traditions, established through a history of past decisions, such as the doctrine of self-defense, or the principle of fair use, or the more narrowly applicable first-sale doctrine. In some organizations, doctrine is simply defined as "that which is taught", in other words the basis for institutional teaching of its personnel internal ways of doing business.
