After the victory, the chronicles describe how the Asturian defenders severed the heads of Muslim leaders, including Ibn al-Qitt, and posted them on spikes on the battlements of the city walls for all to see. A portion of the wall south of the city's main cathedral lies next to a street called Calle Balborraz (named for an old gate exiting the city called the Puerta de Balborraz).

He attributes the attack to the Shia movement and says that Ibn al-Qitt was a "prophet".
