Radiocarbon analysis has placed the parchment on which the text is written to the period between AD 568 and 645 with 95.4 per cent accuracy.
The test, which was carried out in a laboratory at the University of Oxford, places the parchment close to the time of Prophet Muhammad, who is generally thought to have lived between AD 570 and 632.
The Quran manuscript is part of the University's Mingana Collection of Middle Eastern manuscripts, held in the Cadbury Research Library. For many years, the manuscript had been misbound with leaves of a similar Quran manuscript, which is datable to the late seventh century.
"The radiocarbon dating has delivered an exciting result, which contributes significantly to our understanding of the earliest written copies of the Quran," said Susan Worrall, Director of Special Collections (Cadbury Research Library).

"According to Muslim tradition, the Prophet Muhammad received the revelations that form the Quran, the scripture of Islam, between the years AD 610 and 632, the year of his death," said Professor David Thomas, Professor of Christianity and Islam and Nadir Dinshaw Professor of Interreligious Relations at the University of Birmingham.
"At this time, the divine message was not compiled into the book form in which it appears today. Instead, the revelations were preserved in 'the memories of men'. Parts of it had also been written down on parchment, stone, palm leaves and the shoulder blades of camels," he said.
"This means that the parts of the Quran that are written on this parchment can, with a degree of confidence, be dated to less than two decades after Muhammad's death.
"These portions must have been in a form that is very close to the form of the Quran read today, supporting the view that the text has undergone little or no alteration and that it can be dated to a point very close to the time it was believed to be revealed," Thomas said.
