It is narrated that Asiya was one of Bani Isra'il. She believed in Allah and prayed secretly and hid her faith from the Pharaoh.
It is related that the Pharaoh killed the wife of the prophet Hizqil. The Pharaoh told her what had happened whereupon Asiya criticized him for what he did. Then the Pharaoh understood that she believed in Allah and had her killed.
Allah knows best.
