What should I do about my daughter's strong attachment to the Taha satellite channel, and would I be sinful if I let her watch a channel that broadcasts songs with music and rhythm for children, which is considered a channel of innovation (bid'ah)?

Children are a trust, and parents are responsible for raising them in a way that benefits them in their religious and worldly lives, and for protecting them from corruption and vices. This is in accordance with the Almighty's saying: "O you who have believed, protect yourselves and your families from a Fire," and the Prophet's (peace be upon him) saying: "Each of you is a guardian, and each of you is responsible for his flock." Therefore, it is not permissible to allow a daughter to watch a channel that broadcasts content harmful to religion and corrupts belief. Instead, a beneficial and permissible alternative should be sought for her.
