Assalamu alaikum Ustadh, I took a loan for my university and was told that you need to pay it off within 6 months to not accrue interest, however I wasn't aware a portion of the money automatically accrued interest when I took the loan. What is the ruling on this and should I make tawba?

Ustadh AbdulAziz al-Haqqan

Yes. And do your best to pay on time.
