My daughter does not want to make up the Ramadan fasts she missed, so what should I do?

You must advise your daughter of the obligation to make up for the fasts she missed. If she deliberately delays making up the fasts without a valid excuse until the next Ramadan (definition) begins, she has sinned and is obligated, in addition to making up the fasts, to feed a poor person for each day. She is permitted to delay making up the fasts until just before the next Ramadan, because it is an obligation that allows for delay. If advice is ineffective and she insists on not making up the fasts, then she can be disciplined by reprimand or by striking, according to its conditions.
