What is "abul-abbas"

Abul-Abbas (also Abul Abaz or Abulabaz) was an Asian elephant given to Carolingian emperor Charlemagne by the Abbasid caliph Harun al-Rashid. The elephant's name and events from his life are recorded in the Carolingian Annales regni Francorum, and he is mentioned in Einhard's Vita Karoli Magni. However, no references to the gift or to interactions with Charlemagne have been found in Abbasid records.
