Praise be to Allaah.
So long as this salary is allocated by the state to anyone
who works in the private sector, because the public interest requires that,
it is not permissible to use tricks to get this reward in ways other than
that which is allowed. In addition to that, this involves lying and
deceiving, which is haraam. For more information please see the answer to
question no. 93579.
And Allaah knows best.
