I owe several people some money. I calculated the total to be around $500. How I owe them is pretty shameful to say, it is close to stealing. Although they would probably never know I owe them, but I feel bad and I want to pay them back. But sadly I cannot afford it now. So is there any Kaffara (like fasting) for this?
Also if I give the Kaffara now and later pay the money back when I am able to, will this Kaffara be regarded as Nafl?
