What is the ruling on working in the sale of internet subscriptions, chat programs, televisions, and satellite dishes, knowing that their use in unlawful (haram) ways is highly probable, and is it obligatory to refrain from selling to whoever is suspected of using them in unlawful ways, despite the difficulty of implementation and monitoring users?

The rulings on the matters mentioned are related to their usage. If they are used for permissible purposes, then they are permissible. If they are used for forbidden purposes, then they are forbidden, because the means take the rulings of their ends. Those who request these matters are of three types:

First: One who knows or has strong reason to believe that they will use them for forbidden purposes. In this case, it is not permissible to sell or provide these matters to them.

Second: One who knows or has strong reason to believe that they will not use them for forbidden purposes. In this case, there is no objection to selling or providing them to them.

Third: One whose situation is unknown. In this case, one deals with them according to the general state of people. If it is likely that they will not be safe from forbidden use, then dealing with them is prohibited; otherwise, it is permissible. If it is proven that one of them uses the internet for forbidden purposes after it has been provided, then it is obligatory to cut it off from them if possible without harm. If it is not possible except with harm, then it is not obligatory to cut it off, but the contract must not be renewed.
