A fragment of a Koran manuscript is seen in the library at the University of Birmingham in Britain July 22, 2015. A British university said on Wednesday that fragments of a Koran manuscript found in its library were from one of the oldest surviving copies of the Islamic text in the world, possibly written by someone who might have known Prophet Mohammad. Radiocarbon dating indicated that the parchment folios held by the University of Birmingham in central England were at least 1,370 years old, which would make them one of the earliest written forms of the Islamic holy book in existence.
