My question is the following: what is the Shariah point of view about working in the Central Bank of a Muslim country where both interest and non-interest based banks exist and the Central Bank deals with both kinds of banks? Many Muslim countries accommodate both the interest-based traditional banking system and Islamic banking, and their Central Bank needs to deal with both kinds of banks. In this situation, is it halal to work in that kind of Central Bank?

All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

It is permissible (halaal) to work in the Central Bank in doing lawful duties, such as issuing currency and the like of lawful activities that do not involve interest. As for work duties that do involve interest, such as interest-based loans and the like, it is impermissible to work in them.

Allah knows best.
