Is it permissible to sell foods which contain pork or alcohol? There are many Muslims in America who own grocery stores where they sell beer, pork and tobacco, or they work in such stores.
Praise be to Allaah.
It is not permissible to sell that which it is haraam to eat or to use – this includes the things mentioned in the question.
