Muslim working as
    a doctor in the kaafir army
Question

                What is the ruling on working as a
      doctor in the army of the kuffaar who are not in a state of war with the Muslims?
Praise be to Allah.We put this question to Shaykh Muhammad ibn Saalih
    al-Uthaymeen, may Allaah preserve him, with whom we had a conversation which is
    summarized below:
Shaykh: Is this so that he may gain experience, or what?
- He is a doctor who is treating their sick, but they are not in
    a state of war.
Shaykh: And they are not at war with the Muslims?
- It is possible that they may be at war with the Muslims in the
    future.
Shaykh: We do not give the future precedence over the present
    (i.e., we do not count on that or take it into consideration).
- This questioner says, 'I work in a place where the soldiers are
    not fighting the Muslims. But it is possible that some of the army may be fighting them in
    other places, and it is possible that we may be involved in such fighting in the future,
    but the military bases where I work now are not involved in fighting against the
    Muslims.
Shaykh: But is this nation (in which this army is) one of those
    who are fighting the Muslims?
- The questioner is working for the American army, he is a Muslim
    working in America.
Shaykh: Allaah, may He be glorified and exalted, says
    (interpretation of the meaning): Allaah does not forbid you to deal justly and
    kindly with those who fought not against you on account of religion and did not drive you
    out of your homes. Verily, Allaah loves those who deal with equity. [al-Mumtahinah
    60:8].
- And what if they are not driving us out of our homes, but they
    are helping others to do so, as mentioned in the next aayah?
Shaykh:  It is only as regards those who fought you on
    account of religion, and have driven you out of your homes, and helped to drive you out,
    that Allaah forbids you to befriend them [al-Mumtahinah 60:9 
    interpretation of the meaning].
- So if it is clear to him that these people are helping to drive
    us out of our homes, for example, would working for them for a salary come under the just
    and kind treatment mentioned in the aayah?
Shaykh: No doubt it does come under that heading.
- Even if you are working for money and not as a volunteer?
Shaykh: Yes, but they are benefitting from it.
- So how may we sum up your answer?
Shaykh: This is not permissible unless the nation in whose army
    he is working is not fighting the Muslims.
- And not driving them out of their homes or helping others to do
    so?
Shaykh: Yes.
And Allaah knows best.
