Is working in animation sound engineering forbidden, knowing that it will involve voice dubbing, motion effects, and some soundtrack music?

Working in this field is unlawful (haram), as it involves assisting and participating in the preparation of images and music. Music is forbidden (haram), and image-makers will receive the severest punishment on the Day of Judgment. Allah Almighty has forbidden cooperation in sin and aggression. Some scholars consider non-three-dimensional images to be disliked (makruh), with the exception of children's toys. It is advisable to avoid this work and seek another occupation, for whoever fears Allah, He will make for him a way out and provide for him from where he does not expect. If you are certain that your work is only used by children, then there is no harm; however, abstaining and avoiding doubtful matters is preferable.
