paragraph_text: Imamate of the Ahl al-Bayt
  
  Later, most denominations of Shia Islam, including Twelvers and Ismāʿīlīs, became Imamis. Imami Shīʿītes believe that Imams are the spiritual and political successors to Muhammad. Imams are human individuals who not only rule over the Muslim community with justice, but also are able to keep and interpret the divine law and its esoteric meaning. The words and deeds of Muhammad and the Imams are a guide and model for the community to follow; as a result, they must be free from error and sin, and must be chosen by divine decree (nass) through Muhammad. According to this view peculiar to Shia Islam, there is always an Imam of the Age, who is the divinely appointed authority on all matters of faith and law in the Muslim community. ʿAlī was the first Imam of this line, the rightful successor to Muhammad, followed by male descendants of Muhammad through his daughter Fatimah.
  
  This difference between following either the Ahl al-Bayt (Muhammad's family and descendants) or pledging allegiance to Abū Bakr has shaped the Shia–Sunnī divide on the interpretation of some Quranic verses, hadith literature (accounts of the sayings and living habits attributed to the Islamic prophet Muhammad during his lifetime), and other areas of Islamic belief throughout the history of Islam. For instance, the hadith collections venerated by Shia Muslims are centered on narrations by members of the Ahl al-Bayt and their supporters, while some hadith transmitted by narrators not belonging to or supporting the Ahl al-Bayt are not included. Those of Abu Hurairah, for example, Ibn Asakir in his Taʿrikh Kabir, and Muttaqi in his Kanzuʿl-Umma report that ʿUmar ibn al-Khaṭṭāb lashed him, rebuked him, and forbade him to narrate ḥadīth from Muhammad. ʿUmar is reported to have said: "Because you narrate hadith in large numbers from the Holy Prophet, you are fit only for attributing lies to him. (That is, one expects a wicked man like you to utter only lies about the Holy Prophet.) So you must stop narrating hadith from the Prophet; otherwise, I will send you to the land of Dus." (An Arab clan in Yemen, to which Abu Hurairah belonged). According to Sunnī Muslims, ʿAlī was the fourth successor to Abū Bakr, while Shia Muslims maintain that ʿAlī was the first divinely sanctioned "Imam", or successor of Muhammad. The seminal event in Shia history is the martyrdom at the Battle of Karbala of ʿAlī's son, Ḥusayn ibn ʿAlī, and 71 of his followers in 680 CE, who led a non-allegiance movement against the defiant caliph.
  
  It is believed in Twelver and Ismāʿīlī branches of Shia Islam that divine wisdom (ʿaql) was the source of the souls of the prophets and Imams, which bestowed upon them esoteric knowledge (ḥikmah), and that their sufferings were a means of divine grace to their devotees. Although the Imam was not the recipient of a divine revelation (waḥy), he had a close relationship with God, through which God guides him, and the Imam, in turn, guides the people. Imamate, or belief in the divine guide, is a fundamental belief in the Twelver and Ismāʿīlī branches of Shia Islam, and is based on the concept that God would not leave humanity without access to divine guidance.
