What is the required conduct of a Muslim when there is a difference of fatwas among scholars on a single issue?

If the branch is used to bottle alcoholic beverages, even occasionally, then working there is prohibited. This is based on the Prophet's (peace be upon him) saying: "Allah has cursed the one who drinks wine, the one who serves it, the one who presses it, the one for whom it is pressed, the one who carries it, the one to whom it is carried, the one who sells it, the one who buys it, the one who consumes its price, and the one for whom it is bought." However, if it is completely independent and its production line is not used for manufacturing or bottling alcoholic beverages under any circumstances, then there is no harm in working there.
