It’s about the story of pharaoh.

In Ayats 71 to 93 , Allah ask the prophet Muhammad to recite the events related to past Prophets Noah , Moses and Aaron which are mentioned in the past Books and so these Ayats are a confirmation of these past events.

As the prophet himself is unlettered and did not know the contents of these past books , Allah is making him aware that the people who read these books can verify IF he is in doubt.
