What is the ruling on working in the field of visual effects, such as creating explosions, fires, or ground fissures using graphics or computers for films, cinema, and advertisements?

The ruling on working in media depends on the nature and impact of the work. The default is permissibility, unless it is associated with an inseparable Haram (forbidden) element, such as photographing 'awrah (private parts) or spreading corruption. The questioner must review the media materials they will be working with. If these materials are free from Sharia prohibitions, then working with them is permissible. Otherwise, it is not permissible, due to the Almighty's saying: "And do not cooperate in sin and aggression."
