Ulum al Qur'an
The 'Imam' Manuscript
This is the name used for the copy which 'Uthman kept himself, and it is said he was killed while reading it. [Ibn Said: al-Tabaqatal-kubra, Cairo, n.d., Vol. 111, (1). pp. 51-2.]
According to some the Umayyads took it to Andalusia, from where it came to Fas (Morocco) and according to Ibn Batuta it was there in the eighth century after the Hijra, and there were traces of blood on it. From Morocco, it might have found its way to Samarkand.
