What is the ruling on the salary of a female presenter who hosts educational programs for children that include songs, and wears a wig instead of a hijab?

This question is general, and the answer requires elaboration:

1. If the singing includes music, it is forbidden, and its being for children does not make it permissible, due to the Prophet’s (peace be upon him) saying: “There will be people from my Ummah who will consider unlawful sexual intercourse, silk, intoxicants, and musical instruments to be lawful.” 2. If the singing does not include music but is heard by non-mahram men, it is not permissible, because a woman is not allowed to sing with her voice for anyone other than her husband, her mahrams, and her children. 3. The fact that the songs are about transportation methods or fruits and vegetables and are for children does not justify permitting singing on the radio or television. 4. Wearing a wig is not permissible, due to the Prophet’s (peace be upon him) saying: “The Messenger of Allah (peace be upon him) cursed the woman who connects hair (to another’s hair) and the one who has it connected, and the woman who tattoos and the one who has it tattooed.”

The advice for the announcer is to stop singing and adhere to her hijab. As for the salary, what was earned in return for forbidden singing or displaying oneself is not permissible to benefit from, and what was earned in return for other work is permissible.
