Is printing restaurant menus that contain prices of alcoholic beverages, and printing posters for songs, unlawful (haram), and what is the ruling on the money earned from them?

The basic principle regarding contracts is permissibility, unless they involve aiding in a reprehensible act, in which case the sale becomes prohibited. This is based on the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Accordingly, it is not permissible to print a price list that includes the price of alcohol, or to print posters for songs.
