In 2015, a graduate student at The University of Birmingham found two pages misplaced in a newer manuscript of The Qur’an. Noticing the text was visibly different, the student notified the university. Radiocarbon Dating places the creation of the pages between 568 CE and 645 CE. If accurate, this means the document could have been written during the life of Muhammad (570 CE- 632 CE).
