A pro-Castilian collaborator could still be a devout Islamic scholar

Evidence

This close collaborator of the Castilians is represented as at the same time a pious person full of Islamic virtues (he preached to the guests he received in his home) and possessing abundant scholarship. His Arabic-language library—books and commentaries (alkitebesytafsires)— he made available to his visitors. — L. P. Harvey, Muslims in Spain, 1500 to 1614, 220

Categorization

• QUESTION: Interesting puzzle: how did a collaborator reconcile preaching Islamic virtues while serving the conquerors? What did his sermons actually say? Harvey gestures at the tension but the internal logic is undocumented.
