What is the ruling on analyzing alcoholic beverage products within a service entity that grants a quality mark and permits product circulation, knowing that supervisors threaten punishment in case of refusal?

It is not permissible to analyze intoxicants (khamr) and unlawful things, because this constitutes cooperation in sin and transgression, which is forbidden by the Almighty's saying: "And do not cooperate in sin and aggression." If you are ordered to do so, you must refuse, even if it leads to punishment or losing your job.
