If I lend money to someone for a week, and I give him a deposit slip to make the deposit for me into my bank account when the loan is due, is that a potential problem of ribbis by asking him to not only return the money but deposit it for me to my account ?
Answer:
This is not considered ribbis.
Depositing a check or cash in the bank is a method of paying you back. Paying back in this way is permitted, just as any other method of payment.
