As a 22-year-old, I recalled that I broke my fast a couple of times when I was younger. It took me years to realize that I owe a Kaffara. I am still a student and live with my parents. What should I do in this situation?
Kaffara is obligatory for every day of deliberate breaking fast beside Qadha of that fast. If you don't have money to feed sixty poor believers, you can fast two months as Kaffara of not fasting deliberately for each day. If you can not do that, you should wait till you are able to earn and feed the poor believers.
Wassalam.
