was succeeded by Uthman ibn Affan, who spread Islam into North Africa, Cyprus, Iran, Afghanistan, and parts of India and Pakistan. Over the next two centuries, Islam expanded into sub-Saharan Africa, Spain, Southeast and Central Asia, and Turkey.
Divisions Within Islam
Uthman was assassinated in 656 A.D. by soldiers who then installed Ali ibn Abu Talib, Muhammad's son-in-law, as Caliph. Ali's followers believed Muhammad had chosen Ali to be Muhammad's heir, and had disagreed with the selections of Abu Bakr, Umar, and Uthman as Caliphs. Ali's claim to the position was challenged by Muawiyah, a kinsman of the murdered Uthman. Five years later, Ali was assassinated by Kharjites, religious dissidents who broke away from the main body of Muslims because they rejected Ali's accepting arbitration to resolve his leadership dispute with Muawiyah. Ali's supporters, or the Shiah al-Ali (or Shiat Ali, partisans of Ali) believed that Ali was the true Caliph and was, in part, divinely inspired. Ali's sons, Hassan and Husayn followed as Shia Caliphs, Hassan dying in 669 or 670 A.D., possibly by poisoning, and Husayn slain by soldiers of his rival, the Sunni Caliph Yazid, in 680 A.D.
The Shia Muslim community has divided further as followers coalesced around several of Ali's descendants or successors, called Imams. The "twelvers," predominant in Iran, believe the twelfth Imam is in hiding and will reveal himself just before judgement day. Ismailis rejected the seventh Imam and practice a spirituality that seeks hidden meaning in scripture. Ismailis ruled much of North Africa as the Fatimid dynasty of Egypt in the tenth through the twelfth centuries, and today are found primarily in Pakistan, Afghanistan, and India. The Sunni majority reject the premise that men can be divine, including Muhammad, Ali, or Jesus, and did not accept any of the Imams who followed Ali. Sunnis remain more committed to traditions and less inclined to accept Shia mysticism. Today, about 15% of the world's one billion Muslims are Shia and 85% are orthodox Sunni.
There are other factions within Islam. Sufis, a name apparently taken from the wool garments they wear, developed around mystical practices and trance-induced revelations. Sufis are found today in Turkey, Syria, and parts of Africa. Other movements have taken reform tracks, such as the Unitarians of Saudi Arabia, also called Wahhabis after their 18th century reformist founder Muhammad ibn Abd al-Wahhab. The conservative Wahhabis are found today in Saudi Arabia and Qatar. Some critics would argue that the Taliban of Afghanistan took conservative reform to an extreme. Other sects or break-away groups include, among others, the Alawis found in Syria and Turkey, the Druze in Lebanon, Syria, Jordan, and Israel, the Ibadhis (Kharjites) in Oman and Africa, the Ahmadiya of Pakistan, and the Zaydis of Yemen.
Religious Guidance
During his lifetime, Muhammad's companions memorized and later transcribed the verses (surrahs) of the Quran as they had been dictated to Muhammad. The Caliph Uthman collected and codified the various versions of the surrahs into one written Quran that became the standard Arabic text used by the world's Muslims today. Present-day Muslims look first to the Quran as a guide to life, then to the Sunnah, or the way of the Prophet (his life as an example for others) as recorded by his early companions, and then
