Grocery
      store selling foods containing pork ingredients
Question

                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 Allah.It is not permissible to sell that which it is haraam
      to eat or to use – this includes the things mentioned in the question.
