Is it considered forbidden to authenticate university degrees without having performed the national service required for new graduates?

If assigning university graduates to this service entails a public benefit and no harm to them, then it is obligatory to adhere to it, and it is not permissible to evade it. However, if the assignment is for no legitimate interest or entails definite harm, then there is no sin in evading it. It is recommended to present the matter to a trustworthy mufti (definition) in the country.
