Dr. Monzer Kahf, a prominent economist and counselor states: “While it is possible to work in a bank without dealing in interest, it is also possible to work in a supermarket without actually selling alcohol, cigarettes, pork and other prohibited things. Hence, selling prohibited things is Haram. It is Haram for the owner to do it and it is also Haram for a worker to sell it. In some prohibited things the prohibition extends to more than selling. For instance, in the case of alcohol, It is Forbidden for a Muslim to handle it on shelves, to hand it to a customer (Muslim or non-Muslim), to carry it to a customer’s car, etc. These functions may not be necessarily Haram for other things like cigarette although selling them is not permissible.”
