ANSWER:

Yes, you must return it back because now you know. 

We needed money so we took a student loan from an agency. I asked my mother if it was interest based or not, she said it wasn’t. In short; I later found out that it was interest based but at that point it was too late and the money is in my bank now, and everything has been concluded. Is the money haram for me even though I didn’t know? If so, do I return the money back to the agency?
