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.

Shia–Sunni relations

Sunni and Shia Islam are the two major denominations of Islam. The demographic breakdown between the two denominations is difficult to assess and varies by source, but a good approximation is that 85-90% of the world's Muslims are Sunni and 10-15% are Shia, with most Shias belonging to the Twelver tradition and the rest divided between many other groups. Sunnis are a majority in most Muslim communities: in Southeast Asia, China, South Asia, Africa, and most of the Arab world. Shia make up the majority of the citizen population in Iraq, Iran, Azerbaijan, and Bahrain, as well as being a politically significant minority in Lebanon. Azerbaijan is predominantly Shia; however, practicing adherents are much fewer.Indonesia has the largest number of Sunni Muslims, while Iran has the largest number of Shia Muslims (Twelver) in the world. Pakistan has the second-largest Sunni as well as the second-largest Shia Muslim (Twelver) population in the world.

The historic background of the Sunni–Shia split lies in the schism that occurred when the Islamic prophet Muhammad died in the year 632, leading to a dispute over succession to Muhammad as a caliph of the Islamic community spread across various parts of the world, which led to the Battle of Siffin. The dispute intensified greatly after the Battle of Karbala, in which Hussein ibn Ali and his household were killed by the ruling Umayyad Caliph Yazid I, and the outcry for revenge divided the early Islamic community. Today, there are differences in religious practice, traditions, and customs, often related to jurisprudence. Although all Muslim groups consider the Quran to be divine, Sunni and Shia have different opinions on hadith.

Husayn ibn Ali

Ḥusayn ibn ‘Alī ibn Abī Tālib (Arabic: الحسين بن علي بن أبي طالب‎‎; 10 October 625 – 10 October 680) (3 Sha'aban AH 4 (in the ancient (intercalated) Arabic calendar) – 10 Muharram AH 61), also spelled as Husain, Hussain or Hussein, was the son of Ali ibn Abi Ṭalib (fourth Rashidun caliph of Sunni Islam, and first Imam of Shia Islam) and Fatimah Zahra (daughter of Muhammad) and the younger brother of Hasan ibn Ali. Husayn is an important figure in Islam, as he is a member of the Ahl al-Bayt (the household of Muhammad) and Ahl al-Kisa, as well as being the third Shia Imam.

Hussain became the head of Shia Islam and the head of Banu Hashim after the death of his older brother, Hasan ibn Ali, in 670 (AH 50). His father's supporters (Shi'a Ali) in Kufa gave their allegiance to him. However, he told them he was still bound to the peace treaty between Hasan and Muawiyah I and they should wait until Muawiyah was dead. Later, Hussain did not accept the request of Muawiyah for the succession of his son, Yazid I, and considered this action a breach of the Hasan–Muawiya treaty. When Muawiyah I died in 680, Husayn refused to pledge allegiance to Yazid I, who had just been appointed as Umayyad caliph by Muawiyah, because he considered the Umayyads an oppressive and religiously misguided regime. He insisted on his legitimacy based on his own special position as a direct descendant of Muhammad and his legitimate legatees. As a consequence, he left Medina, his home town, to take refuge in Mecca in AH 60. There, the people of Kufa sent letters to him, asking his help and pledging their allegiance to him. So he travelled towards Kufa. At a place near Kufa, known as Karbala, his caravan was intercepted by Yazid I's army. He was killed and beheaded in the Battle of Karbala on 10 October 680 (10 Muḥarram 61) by Shimr Ibn Thil-Jawshan, along with most of his family and companions.
