Is it permissible for her to get an invoice for medication from a pharmacy from which she did not get this medicine?
Question

                I work in a government department and our medical costs are covered by this department; we have to bring an invoice for the cost of medical consultations from any doctor as well as invoices from any pharmacy showing the price of medicine, and the department will cover the cost of these invoices. 

My questions are: 

Sometimes the doctor who treats me prescribes medicine for me, some of which can be found in the pharmacy and some of it cannot, so we buy it from him, but he does not write me an invoice showing the price of these medicines.

Is it permissible for me to get an invoice from any pharmacy to show the price of this medicine, but showing the name of some other medicine that is in the prescription? On one occasion I went to the doctor and my sister was with me, and she had some problems, so she asked the doctor and he wrote a prescription for her. But when I asked him whether I should pay for this consultation, he refused.
 Is it permissible for her to submit it to the department in which my father works, because children get half of their medical costs covered by the department in which the father works?
Praise be to Allah.
    Firstly: 

    The employee should approach his work with an attitude of 
    trustworthiness, dignity and honesty, and should avoid haraam earnings, 
    lying, cheating and deceiving. 

    He should do the work required of him in a proper manner, 
    without cheating in his earnings or doing anything that will lead to regret 
    in the Hereafter. 

    See the answer to question no.
    4651. 

    Secondly: 

    Saying that the medicine mentioned is not available in 
    pharmacies is a dubious statement, because the basic principle is that 
    medicine is more available in pharmacies than in doctors’ clinics; the 
    doctor may have free samples that he gets from (pharmaceutical) companies 
    and the like. 

    Whatever the case, it seems to us, and we know from 
    experience, that if you had looked more, especially in larger pharmacies, 
    you would certainly have found the medicine that you were looking for or you 
    would have found a suitable alternative to it. It does not seem to us that 
    there is any concession concerning what you are asking about, especially as 
    it is not a case of necessity. So it is not permissible to hasten to tell 
    lies or resort to deceit and tricks when there is no case of necessity and 
    no pressure to do so. 

    Even if we assume that there is no alternative for this 
    medicine, and that it is only available from this doctor (which cannot be 
    the case), either the doctor should sell it with an invoice, or you can talk 
    to your superiors at work so that they can find out the facts about the 
    matter. 

    Thirdly: 

    If children have half of their medical costs covered, as you 
    say, then it is not permissible for them to submit papers showing anything 
    but the true facts. If on this occasion you did not pay any of the costs for 
    this consultation, then you do not have the right to ask the administration 
    at work for anything. 

    If you did pay for it, then you have the right to ask for 
    what you are allowed to, according to the conditions stipulated by your 
    father’s work, but that is on condition that the papers you submit are 
    truthful and are not made up.
