What is the ruling on my working for a paint company that uses smuggled gasoline due to its scarcity, and does the principle of "warding off harm takes precedence over acquiring benefits" apply to this issue, especially if stopping the use of gasoline will lead to the company's closure and the loss of livelihood?

If the state prohibits the use of gasoline to ward off a public harm, then the prohibition must be observed outwardly and inwardly. However, if the owner of a company is compelled to use it to earn his livelihood or the livelihood of those he supports, and finds no other means, then necessity is assessed according to its measure, without exceeding it.
