Why are theatrical masks uncommon in much of the Muslim world?

Theatrical masks are uncommon in much of the Muslim world primarily due to the religious principle of aniconism, which involves the opposition to the use of icons or visual images to depict living creatures.12

Within Islamic thought, there is a traditional assumption that God is the sole creator of life. Consequently, producing a likeness of a living being has historically been viewed by some orthodox scholars as an attempt to rival God, which is considered a violation of the sanctity of life. This theological caution regarding human portrayal and its potential connection to idolatry has led to a traditional wariness toward representational arts, including theatre involving live actors or masks.13

Because of these concerns, the use of masks in theatrical performances is practically unknown in the Muslim world. Even when shadow theatre evolved in the East during the Middle Ages, the puppets were often intentionally punched with holes to demonstrate that they were lifeless, thereby avoiding the implication of creating a living image.3
