What do you think are Pamuk's intentions in referring to the canon of Islamic literature in The Black Book?

Pamuk frequently refers to Islamic scripture in the novel The Black Book. He refers to the Surahs and the prophecies about the end of time several times. His intent, it seems, is to show how these works are relevant to the events of their time. He relays stories about listening to the elders teaching when he is at a funeral, and they address many current events and discuss what they mean in light of the poetic works of scripture, particularly the verses that speak about people who act against what they believe.
This is also pertinent to the story at large because it shows the narrator's feelings. He feels like he is acting against his own beliefs because of his heartbreak and fear at his wife's departure. He lies to everyone around him telling them that she is still around but eventually can't keep up the ruse and has to go seek her out himself. He also believes that she is acting against her beliefs by leaving her husband.
