In Islamic mythology, a Hafaza (aka Hafza) is a type of angel. It is roughly equivalent with the Christian concept of a guardian angel.

Each person is assigned with four Hafazas, two of which keep watch during the day and two during the night. They help the soul fight attacks from Shaitan (the Devil) and djinn. The Hafazas keep track of each and every good and bad deed that their person performs in their books. At Judgement day they are used to determine if the person is worthy admission into heaven.
