Works & Achievements
Under Uthman, a commission of scribes led by Zayd ibn Thabit established the definitive canonical version of the Quran. This undertaking is considered one of the most significant in world religious history, as it permanently fixed the sacred text of Islam.
The armies of the caliphate, under the command of Abdullah ibn Sa'd, launched the first major expedition into Ifriqiya (present-day Tunisia), laying the groundwork for the gradual Islamization of the Maghreb.
Uthman authorized the governor of Syria, Mu'awiya, to build a naval fleet. It went on to win the Battle of the Masts against Byzantium (655) and enabled the conquest of Cyprus, marking the beginning of Islamic maritime power in the Mediterranean.
Uthman reorganized the empire's provinces, appointed governors, and improved tax collection. He also developed the infrastructure of Islamic cities, most notably the Prophet's Mosque in Medina.
The caliphate's troops extended their control to the Caucasus, consolidating the empire's northeastern borders and paving the way for the gradual Islamization of these regions.
Anecdotes
Uthmān ibn Affān was nicknamed 'Dhū al-Nūrayn' (the one with two lights) because he successively married two daughters of the Prophet Muhammad: Ruqayyah, and then, after her death, Umm Kulthūm. Such an honor was unprecedented and reflected the deep trust the Prophet placed in him.
Even before becoming caliph, Uthmān was renowned for his extraordinary generosity. During the preparation of the Muslim army for the Battle of Tabūk (630), he personally funded a third of the expedition, providing horses, camels, and supplies — earning him high praise from the Prophet.
It was under Uthmān's caliphate that the canonical version of the Quran was established. Noticing that divergent recitations were spreading throughout the empire, he tasked Zayd ibn Thābit with compiling a single authoritative text. All other versions were subsequently destroyed to prevent discord among the faithful.
Uthmān was the first caliph to die a violent death. In 656, a group of rebels from Egypt and Iraq besieged his home in Medina. He refused to flee or allow his supporters to fight on his behalf, hoping to prevent a civil war among Muslims, and was assassinated while reading the Quran.
A prosperous merchant from the Quraysh tribe before the advent of Islam, Uthmān was one of the earliest converts to the faith. His wealth allowed him to purchase and free enslaved people who had converted to Islam, and to fund the nascent Muslim community at several critical moments.
Primary Sources
The Prophet said: 'Whoever finances the army in the hour of hardship shall have Paradise.' Uthman said: 'I will take care of that,' and he brought nine hundred saddled camels and one hundred horses.
Uthman ordered Zayd ibn Thabit to gather the Quranic pages and collate them, then had faithful copies sent to the major cities of the empire, commanding that all other versions be burned.
The rebels besieged him in his home for forty days. Uthman refused to let blood be shed in his name and told his defenders to return to their homes, then continued reading the Quran until they reached him.
Uthman ibn Affan was a man of extreme modesty; the angels themselves, according to the Prophet, would veil themselves before him. He was among the ten to whom Paradise was promised during their lifetime.
The Prophet said: 'The most deserving person to lead this Islam after me is Abu Bakr, then Umar, then Uthman.' And he thus indicated the order of the caliphs to come.
