Fereydun goes forth to fight against Zahhāk, who has already left his capital, which falls to Fereydun with small resistance. Fereydun frees all of Zahhāk's prisoners, including Arnavāz and Shahrnāz. Kondrow, Zahhāk's treasurer, pretends to submit to Fereydun, but discreetly escapes to Zahhāk and reports to him what has happened. Zahhāk initially dismisses the matter, but he is incensed to learn that Fereydun has seated Jamshid's daughters on thrones beside him like his queens, and immediately hastens back to his city to attack Fereydun. Zahhāk finds his capital held strongly against him, and his army is in peril from the defense of the city. Seeing that he cannot reduce the city, he sneaks into his own palace as a spy and attempts to assassinate Arnavāz and Shahrnāz. Fereydun strikes Zahhāk down with his ox-headed mace, but does not kill him; on the advice of an angel, he binds Zahhāk and imprisons him in a cave underneath Mount Damāvand. Fereydun binds Zahhāk with a lion's pelt tied to great nails fixed into the walls of the cavern, where Zahhāk will remain until the end of the world.
