What is the ruling on manufacturing and supplying inks to a client for use in printing on alcoholic beer boxes, knowing that this percentage represents 2% of total supplies, and that the client may resort to another supplier if we do not supply them?

It is impermissible to manufacture inks used for printing on alcoholic beer boxes if you know that the importer intends them solely for this purpose. This is because means take the ruling of their ends, and whatever leads to the forbidden is itself forbidden. Scholars have explicitly stated the impermissibility of selling grapes to someone who will use them to make wine. This falls under the general meaning of the Almighty's saying: "And do not cooperate in sin and aggression." The export of the product is not justified by the fact that the importer might resort to someone else, or by the small quantity used, for what is forbidden, both its little and its much must be avoided.
