55. Can a Muslim sell alcohol and other haram products?

There are two aspects to this situation. Firstly, if you are a businessman and are making these items available for sale, then you are doing so voluntarily to augment your profits. Such an approach is not advisable. Secondly, if you are a part of an organization (hospitality or aviation) where you are required to serve such items, and there is no choice, then as a worker you should follow the norm until you get a chance to change your situation.
