What is the ruling on working in an engineering consultancy office that provides electrical designs for a tobacco company?
Since smoking is forbidden (haram), it is not permissible to assist in it in any way, based on the words of the Almighty: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Therefore, it is not permissible to work in an office that requires illuminating a place designated for the manufacture of cigarettes, even if the manufacturing or selling is not done directly, because this is considered a form of assistance in a forbidden activity and participation in sin. And whoever gives up something for the sake of Allah, Allah will compensate him with something better.
