In Islam, places which are allocated for the use of Haram activities are forbidden to enter even if it is not for consuming the Haram. The reason for this is that these are places which gain the wrath and the curse of Allah and also as a Muslim one must ensure that their outwardly actions do not lead others to doubt them, therefore going in to Pubs, Clubs, Casinos, dance bars etc could make a person who sees this individual think that they are going in for the wrong reasons.
Allah’s Messenger (may Allah bless him and grant him peace) cursed ten people in connection with alcohol:
“…the one who distils it, the one for whom it has been distilled, the one who drinks it, the one who transports it, the one to whom it has been brought, the one who serves it, the one who sells it, the one who utilizes money from it, the one who buys it and the one who buys it for someone else.” (Tirmidhi and Ibn Majah transmitted it).
And Allah knows best!
