Four other sections of this Qur’an survive, but the section in the Khalili Collection is the only one that retains a commissioning certificate, which was revealed during conservation work done on the manuscript since it entered the Collection. The certificate records that the Qur’an was copied for the library (khizanah) of the Zangid prince Qutb al-Din Abu’l-Muzaffar Muhammad ibn Zangi ibn Mawdud ibn Zangi, who ruled over Sinjar, Khabur and Nisibin in northern Mesopotamia between 1198 and 1219 AD. Under any circumstance, this Qur’an would have been considered one of the finest 13th-century Qur’ans known, but the precise nature of its dating and provenance increases its importance greatly.
