هل بيع طبق الستلايت (الدش) العربي يُعد إثماً؟

It is permissible to sell a satellite dish to someone known to use it for permissible purposes. It is not permissible to sell it to someone known or believed to use it for فساد (corruption/immorality), due to the Almighty's saying: (And cooperate in righteousness and piety, but do not cooperate in sin and aggression). If it is possible to return it to the seller, even for part of the price, then that is permissible.
