It's widely believed that the Islamic Prophet Muhammad received the revelations later contained in the Koran in 610 A.D. until his death 632 A.D. Recently, however, fragments of the oldest-known copy of the Koran were analyzed by scientists at the University of Birmingham in England and the results were surprising. Based on radiocarbon dating, fragments of the holy book originate from 568 to 645 A.D. The timing contradicts the belief that Muhammad’s third successor, Uthman, oversaw the final assembly of the text, which was first formally presented in 653 A.D. The finding also opens the door to the possibility that the Koran may have been created as early as two years before the Prophet was born.
