Is it permissible to take a sum of money in exchange for issuing a marriage permit from abroad, knowing that the employees responsible for completing the transaction do not receive a fee?

It is not permissible to lie by saying: (The one I spoke to wants such and such), and you must repent from this. Similarly, it is not permissible to take money in this manner, because this person is dealing with you as an agent, and therefore it is not permissible to take anything from him except with his knowledge.
