Q: Concerning the fasts which I hadn’t observed during the early years of
post-puberty, ought I to pay kaffarah in addition to observing the compensatory
fasts?
A: You must compensate for all the missed fasts; assuming you hadn’t fasted
without a legitimate excuse, you must – in addition to the compensatory fasts –
pay kaffarah which is tantamount to either fasting for two months per missed
fast or by satiating 60 needy persons (or donating ¾ kg food to each of the 60).
