Asalamu Alaykum Warahmah.Dear brothers Iam working in a business center as a cleaner under a sub agency which is assigned to clean the business center, so this business center in which Iam working is run and owned by a bank,so I feel confussed if my earning from that work lawful or unlawful.what is the rulling for this question. Jazakallaahu Khayraa

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

It is permissible to work in this business centre even if it is owned by a Riba-based bank if your work is related to lawful matters and it does not have any relation with the Riba-based activities of the bank. This is because it is permissible for a Muslim to deal in lawful matters like selling, purchasing and hiring with someone who deals with Riba because the Prophet and his companions used to deal with the Jews in selling, purchasing and hiring although the Jews used to deal with Riba and bribery.

However, we advise you to abandon working in such institutions if there is no need for it because Riba-based banks are among the institutions which declared a war with Allaah and His Prophet so it is better for a Muslim to keep away from anything that is related to such institutions even though it is permissible in principle.

Allaah Knows best.
