The two oldest illustrated Arabic manuscripts are copies of Abd al-Rahman al-Sufi's Treatise on the Fixed Stars. One of these is preserved in the Bodleian Library, Oxford (Ms. Marsh 144).
"The pictures show the configurations of the stars in the forty-eight constellations recognized by Ptolemy, but the figures are dressed in Oriental rather than classical Greek garb. Al-Sufi wrote in his text that although he knew of another illustrated astronomical treatise, he copied his illustrations directly from images engraved on a celestial globe, indicating that he was not working in a manuscript tradition. According to the eleventh-century scholar al-Biruni, al-Sufi explained that he had laid a very thin piece of paper over a celestial globe and fitted it carefully over the surface of the sphere. He then traced the outlines of the constellations and the locations of individual stars on the paper. Al-Biruni later commented that this procedure 'is an [adequate] approximation when the figures are small but it is far [from adequate] if they are large.' The Oxford manuscript of al-Sufi's text was copied from the author's original by his son" (Bloom, Paper Before Print. The History and Impact of Paper in the Islamic World  143-44 and figure 51).

The other copy of this work in Leningrad (St. Petersburg) "dated 396/1005-6 and 02/1011 and was copied from Sufi's holograph completed in 355/965 and dedicated to the Buwayhid 'Adud al-daula" (D. S. Rice, "The Oldest Illustrated Arabic Manuscript," Bulletin of the School of Oriental and African Studies, University of London, 22 (1959) 207-220, quotation from p. 207).
