It is possible that this is another Spanish version of the name of Abu Bakr ibn abd al-Aziz, King of Valencia 1075-1085, elsewhere called Abdalla Azis in the Chronicle.
There was a garden nigh unto Valencia which had belonged to Abenalhazis, and the Cid asked Abeniaf to give it him, that he might take his pleasure there when he was disposed to solace himself.
