Is it obligatory to require tenants not to install satellite dishes?

Question:
The questioner says: We have apartments for rent, and we require that no satellite dish be installed or brought in. Because people’s interest in the apartments decreased, we lowered the rent. Is that sufficient? Or is it necessary to also require that no television be brought in? Knowing that this leads to tenants, or some of them, avoiding this type of apartment, what is required by the Shari'ah?

Answer:
You did well in being cautious about installing satellite dishes, because satellite dishes bring in corrupt satellite channels, so you did well in requiring that they not be installed. If the rent decreases and people come to you, that is where the blessing will be, if Allah wills; the blessing will be for you in that. As for the matter of a television that does not have a satellite dish, it is less harmful than a television that has a satellite dish. If you know that its owner uses it for what is wrong, you may prevent him from doing so and evict him from it. But if he uses it in an ordinary way, using it in an ordinary way and not using it for forbidden matters, there is no harm in that.
