What is the ruling on working in customs in the Holy Quran Society section?

The fundamental principle regarding customs is prohibition, unless the state is compelled to impose them to establish projects and provide services to its citizens, in which case it is permissible to implement them. However, if controls are absent, then taking money becomes an injustice, and it is not permissible to work with them due to the resulting assistance in wrongdoing. If the intent is for a person to work in a Quranic society, and their work is specifically related to customs matters such as monitoring and paying them, and so forth, then there is no harm in it.
