What is the ruling on working as an advertisement and reports designer at the Central Bank or the Monetary Authority, knowing that most of the publications are awareness campaigns and general statistics?

There is no objection to working in design for the Central Bank if there is no direct connection to or assistance in forbidden acts. However, it is safer to work for an entity that does not deal with forbidden matters at all. But if the work involves direct assistance in usury or other forbidden acts, or promoting them, then it is forbidden, based on the Almighty's saying: "And do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty."
