Working in government departments in a state that rules by man-made laws

Question:
The questioner asks: How should a Muslim act if he works in government departments in a Muslim state, but it rules by man-made laws?

Answer:
Regulations that do not contain any permission or prohibition, but are merely regulations to organize work and manage traffic on the roads, these are permissible regulations, and there is nothing wrong with them. As for those by which judgment is rendered between people in disputes and conflicts, this is not to be done except by the Shari'ah.
and that they judge between them So those are the wrongdoers. Judging between people and settling disputes is to be done only by the Book, the Sunnah, and the Shari'ah. As for regulations that organize people's interests, there is nothing wrong with those, such as traffic regulations, labor regulations, and regulations on hiring domestic workers. Yes.
