Is it permissible to trade in alcohol and pork if they are sold to non-Muslims?

It is impermissible to trade in foods that Allah has forbidden, such as intoxicants and pork, even with disbelievers. This is based on the Prophet, peace and blessings be upon him, who said: "Indeed, when Allah forbids a thing, He also forbids its price." Furthermore, the Prophet, peace and blessings be upon him, cursed ten categories of people concerning intoxicants.
