The Samarkand Kufic Quran (also known as the Uthman Quran, Samarkand codex, Samarkand manuscript and Tashkent Quran) is an 8th or 9th century manuscript Quran written in the territory of modern Iraq in the Kufic script. Today it is kept in the Hast Imam library, in Tashkent, Uzbekistan.
In local Uzbek tradition, it is said to have belonged to the third caliph, Uthman ibn Affan.
Based on orthographic and palaeographic studies, the manuscript probably dates the 8th or 9th century. Radio-carbon dating showed a 95.4% probability of a date between 765 and 855.
The copy of the Quran is traditionally considered to be one of a group commissioned by the third caliph Uthman; however, this attribution has been questioned, although no evidence was proffered. In 651, 19 years after the death of the Islamic Prophet, Muhammad, Uthman commissioned a committee to produce a standard copy of the text of the Quran (see Origin and development of the Quran). Five of these authoritative Qurans were sent to the major Muslim cities of the era, and Uthman kept one for his own use in Medina, although the Samarkand Quran is most likely not one of those copies. The only other surviving copy was thought to be the one held in Topkapı Palace in Turkey, but studies have shown that the Topkapı manuscript is also not from the 7th century, but from much later.
Uthman was succeeded by Ali, who took the uthmanic Quran to Kufa, now in Iraq. The subsequent history of the Quran is known only from legends. According to one of them, when Tamerlane destroyed the area, he took the Quran to his capital, Samarkand, as a treasure. According to another, the Quran was brought from the caliph of Rum to Samarkand by Khoja Ahrar, a Turkestani sufi master, as a gift after he had cured the caliph.
