Gilchrist's dating of any Kufic manuscript to the later 8th century has been criticized by other scholars, who have cited many earlier instances of early Kufic and pre-Kufic inscriptions. The most important of these are the Quranic inscriptions in Kufic script from the founding of the Dome of the Rock in Jerusalem (692).[16] Inscriptions on rock Hijaaze and early Kufic script may date as early as 646. The debate between the scholars has moved from one over the date origin of the script to one over the state of development of the Kufic script in the early manuscripts and in datable 7th-century inscriptions.
