Is the commission I received permissible, given that it was for my mediation between my company and another contracting establishment, with my company's approval, but the other establishment did not submit its official documents to the ministry and was delayed in the work, which led to the project being withdrawn from them? If it is permissible, may I legally demand the rest of the agreed-upon amount, despite the absence of documents proving the agreement? And if it is impermissible, must I return it to the establishment that gave it to me, considering that I distributed part of it to employees and it is difficult to recover, and the establishment has closed down and I cannot reach them?
