Selling bricks which one does not own
Q: If I don’t have stock in my business, can I sell the goods? For example, a client comes and purchases a load of bricks and wants it delivered to his house. He pays us for the bricks and delivery, and though we don’t have it in stock, we accept the money. We then collect the bricks from the brick manufacturer and deliver it directly to the client’s house. Is this permissible?
