How Pamuk's “My Name is Red” in particular complex between historical and philosophical themes into fictional narrative ? Please help me

The narrator explains, “A cleric by the name Nusret, who preached at the Bayazid Mosque and claimed to be descended from Our Glorious Prophet Muhammed, had made a name for himself during this period of immorality, inflation, crime and theft.” The Prophet Muhammad is a credible and respected figure among the Muslims. Nusret associates himself with the prophet to upsurge his believability among the listeners of his preaching.
