Is money earned from a nursery that has a television on which music, songs, and images of 'awrah (parts of the body that must be covered in Islam) are displayed considered unlawful money?

If the money is earned from a permissible nursery, then it is not haram. However, you must change the evil by advising your mother to replace music, songs, and nude pictures with permissible things, because music and songs are haram and it is not permissible to listen to them, and looking at nude pictures is haram.
