I accidentally entered to a financial company of US that deals with Credit Cards, Payment Solutions and have a child company as a Bank by looking at the Fatwa given in Darul-Ifta Deoband (Should I work at Oracle Financial Services in the Banking Domain? - IslamQA) .
I am working in the document management team that updates the documentation for the credit cards of the clients including Terms & conditions, Annual rates etc using a Documentation software. I don’t perform any calculations of Interest amount of the Clients, just updating the documentation when there is a changes in the policies of the clients for the year/quarter. They mailed us that some policies have been changed including Interest rates, so we just have to update the documents that’s it and revert back the documents to them. I am still looking to change the job but I just joined and it will take time for me to get the new job. So, please advice me, am I considered sinner in doing this job?
