What is the ruling on purchasing cinema tickets, and the ruling on prizes for sold film tickets without entering the cinema to watch?

The ruling on purchasing cinema tickets varies depending on what is being shown: If it is free from forbidden acts, there is no legal impediment. However, if it contains forbidden and unlawful content, then it is not permissible to buy, sell, or deal with it, because a means to the forbidden is itself forbidden.

As for prizes associated with tickets: If they are for entry to a forbidden cinema, or if a person pays something to obtain them, then this is not permissible, as it is either an encouragement to the forbidden or a form of gambling, both of which are forbidden. However, if there is nothing forbidden in the cinema and the person does not pay anything extra to obtain the prizes, then there is no harm in taking them.
