Is the questioner sinful for having a television in her house, and is she entitled to remove it, or is its presence acceptable under certain conditions, given that her husband used to spend his time outside the house watching matches before he brought the television, and that he added non-religious channels for the children?

You are right in your perception of the danger and corruption broadcast by satellite channels. Television is a double-edged sword, and many channels predominantly feature programs that are corrupt. Therefore, it is not permissible to allow this type of channel into homes, especially those that corrupt beliefs and ideas, raise doubts, and even children's channels.

If your husband has brought such channels into the home, he has erred and must get rid of them, keeping only what is beneficial. He should content himself with channels that are useful for him, his family, and his children. We advise you to discuss this with your husband gently and kindly, focusing on the welfare of the children and your concern for them, while being careful not to be overly strict, which could lead to discord.

Scholars have inferred from Allah's saying about intoxicants and gambling: "And their sin is greater than their benefit," that anything whose harm outweighs its benefit is forbidden.
