We will discuss if these so claim earliest Quranic Manuscript really goes back to the time of Uthman the third Caliph. These Manuscripts are the Topkapi and the Samarkand Manuscript.
First of all we will introduce the script which was use back then during the time of Muhammad and the time of Uthman when the Quran was Canonized.
I will discuss the KUFIC Script, MASHQ Script, the al-Ma'il script, the Naskh script and other Quranic Manuscripts so that we can have a clear understanding of the script which was used back then before the Quran was canonized by Uthman and these will be one of the evidences which will dismiss this claim of the Early Qur’anic Manuscript being the same with the modern edition Quran.
