Uthman ibn Affan: Dhun-Nurayn

Where Umar's story is one of dramatic reversal, Uthman ibn Affan's is one of quiet generosity and painstaking stewardship — a wealthy merchant who gave his fortune to the cause, married two of the Prophet's ﷺ own daughters, and left as his most enduring legacy the very text of the Quran that Muslims read today.

Dhun-Nurayn: possessor of the two lights

Uthman came from the Umayyad clan of the Quraysh, a wealthy and respected family of Meccan merchants, and was among the earliest converts to Islam, accepting the faith through the persuasion of Abu Bakr. His closeness to the Prophet's ﷺ own household became direct when he married Ruqayyah, one of the Prophet's ﷺ daughters. When Ruqayyah died in 624 CE, the Prophet ﷺ gave Uthman another of his daughters, Umm Kulthum, in marriage. Having married two of the Prophet's ﷺ daughters in succession, Uthman became known as Dhun-Nurayn, "possessor of the two lights" — a title unique to him among the companions.³⁴⁶

Generosity in hardship

Uthman's wealth and his willingness to spend it for the community are among the most consistently reported details of his life. Two episodes stand out. When Medina's Muslims had no reliable source of fresh water apart from a well named Ruma, owned by a man who charged for its use, Uthman is remembered as having purchased the well — in some versions purchasing a half-share and later the whole — and dedicating its water free of charge to the public.³⁴⁵ Separately, when the Prophet ﷺ called the community to march to Tabuk during a year of drought and hardship, provisioning the expedition strained Medina's resources severely. A hadith preserved in Jami at-Tirmidhi records the Prophet's ﷺ reaction to Uthman's contribution:

The size of the sum and Uthman's earlier support during Medina's hardest years are why this episode sits alongside the well of Ruma as the clearest evidence of a lifelong pattern of using personal wealth to meet the community's most pressing needs.

The caliphate and the codices

Uthman was chosen as the third caliph in 644 CE by the six-member shura Umar had appointed before his death, and his twelve-year rule (644-656 CE) continued the rapid expansion of the Muslim state into North Africa, Cyprus, and further into Persia.³⁴⁵ His most lasting achievement, however, was neither military nor administrative but textual. As the Muslim state grew and garrisons in different provinces began reciting the Quran with regional variations in wording, Uthman grew concerned that disagreement over the correct text could divide the community. He arranged for the master copy that Abu Bakr had commissioned — by then held by Hafsa, one of the Prophet's ﷺ widows — to be used as the basis for a small number of authoritative copies, written out by a committee that included the original compiler Zayd ibn Thabit, and sent one to each major province, with instructions to retire other written fragments that might cause confusion:

This is why the standard written Quran used across the Muslim world today is called the Uthmanic text — every printed copy, regardless of country or publisher, traces back to the master copies Uthman ordered distributed. The fuller story of how this fits with memorization and manuscript evidence is told in Preservation of the Quran.

Siege and martyrdom

The final years of Uthman's caliphate were troubled by accusations — voiced by a faction of Muslims from Egypt and Iraq — that he had shown favoritism in appointing relatives from his own clan to positions of authority in the provinces, along with other grievances about the conduct of some of those governors. These grievances grew into open rebellion, and in 656 CE a group of aggrieved Muslims traveled to Medina and laid siege to Uthman's house. Uthman, by then in his eighties, refused to order Muslims to fight other Muslims in his defense and refused to step down, believing neither course was right. The siege ended when the rebels broke into his house and killed him while he was reading the Quran.³⁴⁵

His death is remembered across the Muslim tradition as a tragedy without any easy assignment of blame: it opened the period of internal conflict among Muslims known as the First Fitna, whose consequences — including the civil strife that would soon reach his successor, Ali ibn Abi Talib — are treated in this series as a sorrowful chapter in the community's history rather than an occasion for taking sides.³⁴⁵

Legacy

Uthman is remembered in mainstream Sunni Islam among the ten companions given the glad tidings of Paradise in the Prophet's ﷺ lifetime, honored equally for his generosity and for the caliphate that gave the Muslim world a single, settled written Quran. His caliphate is the third chapter of the Rightly-Guided Caliphs, and the fitna that followed his death set the stage for the caliphate of Ali ibn Abi Talib.

In short

Uthman ibn Affan's life joined two threads that might seem at odds — personal wealth spent freely for the community, and a caliphate whose defining act was one of careful preservation rather than conquest. His death by violence at the hands of fellow Muslims marks the point where the unity of the early community first fractured, a story that continues into that of Ali ibn Abi Talib.
