Is money earned from managing a restaurant that serves pork and alcohol permissible (halal) or forbidden (haram)?

The sale of alcohol and pork is forbidden, whether to a Muslim or a non-Muslim, because when Allah prohibits something, He also prohibits its price. The questioner will be rewarded for advising the restaurant owner. It is not permissible to work in a restaurant that sells alcoholic beverages, as taking and recording orders is considered assisting in the sale of alcohol, and Allah has forbidden cooperation in sin and aggression. The worker must repent to Allah. The earnings obtained from alcohol orders are unlawful (haram) and must be disposed of in charitable causes. As for earnings mixed with other lawful earnings, one must dispose of the amount that clears one's conscience.
