Is it permissible to play the game "Sultans: Revenge" which includes monsters with names such as "The Winged Beast" (having a human head and a bird's body, representing the immortal soul) and "Anubis" (a guide and guardian of the dead), knowing that the meanings of these monsters are not apparent to players except by searching in forums, and they only affect gameplay by granting additional rewards upon killing them?

A ruling on electronic games requires full knowledge of them. However, based on the descriptions mentioned, the game does not appear to be forbidden in itself. Nevertheless, it is better to avoid doubtful matters, in accordance with the Prophet's saying: "The lawful is clear, and the unlawful is clear, and between them are doubtful matters about which many people do not know. So whoever avoids the doubtful matters has purified his religion and his honor."
