What is the ruling on purchasing a hotel for investment when one is unable to prevent guests from committing forbidden acts therein?

It is impermissible to purchase a hotel if its owner is unable to prevent the commission of forbidden acts and indecencies therein, as it will become a den of evil and corruption. Providing a safe haven for sinners and criminals is considered cooperation in sin and aggression. It is advisable to invest money in permissible projects that yield lawful profit instead of hotels, which are often not free from the forbidden. Purchase is only permissible if the hotel can be purified and forbidden acts prevented from entering it, but this is unlikely in some countries.
