This writing study is based on the Qur'an manuscripts, and its aims are to determine the distinctions in the group by observing different criteria (channel, order etc). This approach allows the ancient manuscripts to be divided into two major types, the Hijazi script and the Kufic script. Kufic style also has its own subdivisions.Cellard É., "Les manuscrits coraniques anciens", Le Coran des historiens, T.1, 2019, p. 681.
