Will a person be sinful after his death if he installed a multi-channel satellite dish and his heirs used it, or is the sin only on the viewer?

It is not permissible to bring lewd, immoral satellite channels, or those that spread innovations (bid'ah) and destructive ideas, into the home. The one who does so is sinful regarding himself and his family, because he is commanded to protect them from the Fire and is responsible for his flock. Introducing these channels is a deception of the flock and a squandering of it. And whoever leaves this falsehood for those who come after him will bear the sin of those who use it, because he pointed to evil and aided it, and initiated a bad precedent. Thus, he will bear its burden and the burden of those who act upon it until the Day of Resurrection.
