	The medieval Egyptian historian Ibn Abd al-Hakam (d. 971) relates that Abd al-Aziz had a different copy of the Qur'an produced from the version of al-Hajjaj which was sent to him. The Baghdad-based writer Abu Ubayd Allah al-Marzubani (d. 995) praised Abd al-Aziz for promoting the Arabic language; having caused misunderstandings by his own erroneous pronunciation of Arabic, Abd al-Aziz endeavored to learn the correct pronunciation and later made gifts to his petitioners dependent on their mastery of the Arabic language.
