The Succession and the Rightly Guided Caliphs
Abu Bakr, Umar, Uthman and Ali lead the community in turn, as Arab armies conquer an empire and a dispute over leadership opens the Sunni–Shia divide.

Who leads now?
When the Prophet died in 632, the Qur’an was complete but the question of leadership was not settled. While Ali and the Prophet’s family prepared his body for burial, leaders of the Medinan Ansar met at a hall called the Saqifa to choose a leader. Senior Meccan companions hurried there, and after a tense debate Umar pledged allegiance to Abu Bakr, the Prophet’s old friend and father-in-law. The others followed.

Ali, the Prophet’s cousin and son-in-law, did not at first accept. Shia Muslims believe the Prophet had already chosen him, pointing especially to a sermon at the pool of Ghadir Khumm in 632. Sunnis accept that the Prophet praised Ali there but read it as an expression of love and loyalty, not an appointment.

An empire in a generation
Abu Bakr’s short reign (632–634) was spent bringing back tribes that had broken away after the Prophet’s death, in the “Ridda wars”. Under Umar (634–644), Arab armies then defeated the Byzantine and Sasanian Persian empires, both exhausted by decades of war with each other. Syria and Jerusalem, Iraq, Egypt and much of Iran fell within about fifteen years.

Fitna: the first civil war
Umar was murdered in 644 and a council chose Uthman, of the powerful Umayyad clan. Muslim tradition credits him with producing the standard written text of the Qur’an. But his appointment of relatives as governors stirred resentment, and in 656 rebels killed him in his house in Medina.

Ali became caliph at last, but into a civil war, the first fitna (“trial” or “strife”). At the Battle of the Camel in 656 he defeated forces led by the Prophet’s widow Aisha and two senior companions, Talha and al-Zubayr. Then Mu’awiya, Uthman’s kinsman and governor of Syria, demanded revenge for Uthman’s death. The armies met at Siffin in 657; the fighting ended in arbitration, which satisfied no one.

Why it still matters
For Sunnis, the four “rightly guided” caliphs were all great companions of the Prophet, and their era is the model of a just Islamic order. For Shia, the true line of leadership ran through Ali and his descendants, the Imams, and the early caliphate was a political wrong done to the Prophet’s family.

The Prophet left no binding designation. The community rightly chose Abu Bakr, his closest companion, and the four "rightly guided" caliphs (al-Khulafa' al-Rashidun) Abu Bakr, Umar, Uthman and Ali all deserve honour, in that order. Their era is a model of just Islamic rule.

The Prophet designated Ali as his successor, above all at Ghadir Khumm on the way back from the Farewell Pilgrimage, when he said "for whomever I am master (mawla), Ali is his master". Leadership belonged to Ali and his descendants, the Imams, and passing him over was a grave wrong.

The sources were written down long after the events, under Sunni and Shia influence alike. Wilferd Madelung argued that Ali and the Prophet's family had a strong claim that was sidelined by politics; others see an open question that each side later read its own answer into.

Why it matters today
Almost every Muslim is either Sunni or Shia, and the difference began here, in a disagreement over who should have led the community after the Prophet. For Sunnis these decades are a golden age to look back to; for Shia they are the start of a long injustice to the Prophet's family. Respect for both memories matters in any conversation.
