What field should
    he study at university?
Question

                In your humble opinion, what kind of
    knowledge would you encourage Muslims in west, while circumstances have brought us here,
    to obtain while attending secular universities; as I am blanked out as to what to major
    in?
Praise be to Allah.When choosing a specialty, you have to pay attention to
    a number of points:
Your personal abilities: do not choose a specialty that does not suit
        you, lest you fail.

The need of the Muslims for this specialty: so that you can try to fill
        a gap in the Muslim community/Ummah.

Your own inclinations: if a person has the inclination and desire to
        learn, along with the ability to do so, it is very seldom that he does not succeed.

The specialty should be free of things that go against sharee’ah.
        As for specialties in forbidden fields such as music, philosophy, etc., it is not
        permissible to enter them at all.

Then seek the help of Allaah to make the right choice, make sure that
    your intentions are proper, and at all times put your trust in the Most Generous, Most
    Merciful.
