Uthman ibn Affan عُثْمَان بْنُ عَفَّان

In review — pending scholar verification

The third of the four Rightly Guided Caliphs (r. 23–35 AH / 644–656 CE), son-in-law of the Prophet ﷺ twice over (hence Dhu an-Nurayn), and the caliph under whom the standardised mushaf of the Quran was produced.

Overview

ʿUthman ibn ʿAffān (Arabic: عُثْمَان بْنُ عَفَّان) was the third of the four al-Khulafāʾ ar-Rāshidūn (Rightly Guided Caliphs), succeeding ʿUmar ibn al-Khaṭṭāb in 23 AH (644 CE) and ruling for twelve years until his assassination in 35 AH (656 CE). He is honoured by the title Dhū an-Nūrayn ("Possessor of two lights") because he was married successively to two of the Prophet Muhammad ﷺ's daughters — first Ruqayyah, then after her death, Umm Kulthum. He is also one of the al-ʿAsharah al-Mubashsharūn bi-l-Jannah — the ten Companions promised Paradise during their lifetimes (Sahih Muslim 2417).

ʿUthman was an early convert — among the first six men to accept Islam — through the calling of Abu Bakr. He was a wealthy merchant of the Umayyad clan of Quraysh and used his wealth repeatedly for the cause: buying and donating the well of Bi'r Rūmah for free Muslim use, expanding the Prophet's ﷺ Mosque in Medina, and equipping the difficult Jaysh al-ʿUsrah (the army of distress) for the Tabuk expedition (9 AH) — for which the Prophet ﷺ said: "Nothing will harm ʿUthman after what he has done today" (Jami at-Tirmidhi 3700, graded Hasan).

His twelve-year caliphate is divided by classical historians into two distinct halves. In the first six years he continued the expansionary trajectory of ʿUmar; in the second six, internal tensions among the rapidly-expanding Muslim polity grew, culminating in his murder by rebels who besieged his house in Medina. His most enduring achievement was the standardisation of the Quran: the production of a single official codex distributed to all the major centres of the Caliphate (Sahih al-Bukhari 4987), a project that fixed the textual transmission of the Quran for all subsequent generations.

Lineage and conversion

ʿUthman was born in Mecca around 576 CE into the Umayyad clan of Quraysh — wealthy, well-connected, and influential in pre-Islamic trade. He was, before Islam, one of the few literate Quraysh and a respected merchant. He accepted Islam through the call of Abu Bakr in the very early years of the prophetic mission. He was among the first emigrants to Abyssinia (with his wife Ruqayyah) under the Najashi (Negus) for protection from Quraysh persecution, and later migrated to Medina at the time of the Hijra.

Quranic references

  • Surah At-Tawbah 9:117 — "Allah has already forgiven the Prophet and the Muhajirun and the Ansar who followed him in the hour of difficulty…" Classical commentators (Ibn Kathir on this verse) link the "hour of difficulty" to the Tabuk expedition (9 AH), which ʿUthman funded substantially.
  • Surah Az-Zumar 39:9 — "Is one who is devoutly obedient during periods of the night, prostrating and standing [in prayer], fearing the Hereafter and hoping for the mercy of his Lord [like one who does not]?" Several classical commentaries identify this with ʿUthman's nightly recitation of the entire Quran.
  • Surah An-Nur 24:55 — "Allah has promised those who have believed among you and done righteous deeds that He will surely grant them succession upon the earth." Classical exegesis applies this to the four Rashidun, including ʿUthman.

Role during the Prophet's ﷺ life

  • One of the first six men to accept Islam.
  • Married Ruqayyah, the Prophet's ﷺ daughter; emigrated with her to Abyssinia and then to Medina.
  • After Ruqayyah's death (in the days of Badr — ʿUthman was excused from the battle to nurse her), he married her sister Umm Kulthum — earning him the title Dhū an-Nūrayn. The Prophet ﷺ said: "If I had a third [daughter], I would marry her to ʿUthman" (Musnad Aḥmad 21778, graded Sahih by Shu'ayb al-Arna'ut).
  • Funded the well of Bi'r Rūmah and donated it for free Muslim use (Sahih al-Bukhari 2778).
  • Funded the Jaysh al-ʿUsrah for the Tabuk expedition with 300 camels and 1000 dinars; the Prophet ﷺ stirred the coins and said: "Nothing will harm ʿUthman after what he has done today" (Jami at-Tirmidhi 3700, graded Hasan by al-Albani).
  • Was the Prophet's ﷺ envoy to Quraysh at Hudaybiyyah in 6 AH; the Pledge of Riḍwan was taken when a rumour of his death reached the Muslim camp.

The caliphate (23–35 AH)

Standardisation of the Quran

As Muslim communities spread to distant centres — Kufa, Basra, Sham, Egypt — regional differences in recitation began to produce confusion, with some Companions accusing others of recitation errors. Hudhayfah ibn al-Yamān reported the issue to ʿUthman, who, after consultation with the senior Companions, commissioned a unified codex from Ḥafṣah's Ṣuḥuf (the compilation of Abu Bakr's era). Zayd ibn Thābit headed a committee that produced one master copy and several official duplicates dispatched to the major centres; divergent manuscripts were retired (Sahih al-Bukhari 4987). The standardised mushaf ʿUthmān remains the textual foundation of the Quran in every printed edition today.

Continued expansion

Under ʿUthman the conquests continued: into Khurasan, Sindh, North Africa as far as Tunisia; Cyprus came under Muslim rule (the first naval campaign in Islam, led by Muʿāwiyah ibn Abi Sufyan); Persia's remaining provinces fell.

Expansion of Al-Masjid al-Haram and al-Masjid an-Nabawi

ʿUthman expanded both Sacred Mosques substantially during his caliphate, accommodating the growing population of pilgrims and worshippers.

Growing tensions

The second half of his caliphate saw rising criticism from the new urban centres of Kufa, Basra, and Egypt — over governorship appointments (some made from his Umayyad relatives), perceived favouritism, and tax disputes. Provocateurs travelled between cities, fomenting opposition. In Dhu al-Hijjah 35 AH, rebels from Egypt and Iraq besieged ʿUthman's house in Medina. ʿUthman refused to fight back, citing the Prophet's ﷺ counsel to him to be patient. He was killed while reciting the Quran on the morning of 18 Dhu al-Hijjah, 35 AH (17 June 656 CE), aged 82.

Famous hadith on ʿUthman

ʿĀʾishah reported that the Prophet ﷺ was sitting with his garments uncovered, when Abu Bakr entered, then ʿUmar entered — the Prophet ﷺ remained as he was. When ʿUthman entered, the Prophet ﷺ adjusted his garments and said: "Should I not be modest from a man before whom the angels are modest?" — Sahih Muslim 2401
ʿUthman himself reported the Prophet ﷺ said: "The best of you is the one who learns the Quran and teaches it." — Sahih al-Bukhari 5027
Anas reported the Prophet ﷺ ascended Mount Uhud with Abu Bakr, ʿUmar, and ʿUthman; the mountain shook beneath them, and the Prophet ﷺ said: "Be still, Uhud — there is upon you a Prophet, a Siddiq, and two martyrs." — Sahih al-Bukhari 3675

Death

ʿUthman was killed on 18 Dhu al-Hijjah, 35 AH (17 June 656 CE), in his house in Medina, while reciting the Quran. He was 82 years old. He was buried at al-Baqīʿ, the cemetery adjacent to Masjid an-Nabawi. The First Fitna — the civil disturbances that began with his murder — would shape Muslim political history for decades.

Legacy and significance

ʿUthman's most enduring legacy is the standardisation of the Quranic text — an act so consequential that it is the basis on which modern printed copies and the global tradition of memorisation rest. Sunni doctrine ranks him as the third-best of the Companions, after Abu Bakr and ʿUmar. Reverent silence on the disputes that ended his caliphate, paired with belief that he was a martyr who died upholding his trust, is the standard Sunni position (al-Ṭaḥāwiyyah, al-Wāsiṭiyyah).
