A public sector employee received a financial compensation or a gift in exchange for providing a service to someone in the same institution, and this service is outside the scope of his work, even if he did not request it, they wanted to give him this amount. This work is from someone else's job, but due to his position, he knows better how to accomplish this task. He was told to carry out the work and that he would receive a gift or financial amount. Is this act permissible?
