Is it permissible for a Muslim who owns a store selling children's toys that contain images of animate beings, cars that play music, and polytheistic cartoon characters, to sell these toys at reduced prices to avoid significant financial losses that could lead him to debt, despite his knowledge that it is not permissible to continue trading in them?

It is not permissible to sell forbidden items, even if that leads to a loss. As for selling toys that are in the form of animate beings, it is permissible to sell them if they are for children, due to the concession mentioned regarding dolls for girls and similar incomplete images that do not sustain life. However, selling them to adults is not permissible if the image is complete.

It is not permissible to sell anything that contains music, unless the music can be disabled.

It is also not permissible to sell toys in the form of polytheistic cartoon characters; rather, they must be destroyed.

The way out for someone who has bought a forbidden item is to return it to its seller. Otherwise, it is not permissible to sell a forbidden item unless its forbidden form is destroyed.
