"The manuscript might possibly be from the time of Othman Bin Affan who became Caliph many years after the death of the Prophet”... “During the time of the Prophet (pbuh), the Quran was not organised or put in its present day form. Also, there were no colours used.” But there are colors in the Birmingham fragments. Al Sharif explains: “One of these is the red-colour separation between the Bismillah and the two Surahs of Mariam and Taha. It was not customary during the Prophet’s time to separate between the Surahs. This copy seems to be organised in [an] order which was not so during the time of the Prophet."
