Praise be to Allaah.
It is not permissible for you to work in the Central Bank
either directly or by working for a company that maintains and operates the
bank’s equipment, because this involves cooperating in sin and
transgression.
This central bank is responsible for all the banks and for
deciding their interest rates (riba) and enforcing their regulations and
promulgating laws and systems that go against the laws of Allaah.
If you work for a maintenance and operation company there is
no reason why you should not maintain and operate companies that deal with
things that are permissible according to the rulings of sharee’ah, even if
your company has other branches that deal with things that are not
permissible. What is important for you is not to accept work in this field;
you should look for another field where you can operate and maintain things
that are permissible according to sharee’ah.
On this site you will find many fatwas concerning the ruling
on working for riba-based banks and for organizations that guard riba-based
banks or operate programs for them. We have quoted in these fatwas the
comments of the scholars stating that such jobs are haraam, and this applies
completely – if not more emphatically – to companies that take care of these
banks.
