The ruling on one who has left several days of fasting in Ramadan for years

Question:
I have left several days of fasting in Ramadan for years. Is it obligatory for her to make up those days?

Answer:
Yes, she has to make them up, and she has to repent to Allah, and she has to give charity along with that. Three things: making up the fasts, repentance, and charity for each day, half a sa' (a dry measure of about 3 kg). This is because she is one who erred and was negligent. Unless she is poor and cannot afford it, in which case fasting and repentance are sufficient. But if she can afford it, she has to repent to Allah, feel remorse, and seek forgiveness for her negligence and laxity. She has to fast for the number of days she missed, and she has to feed a poor person for each day, half a sa' of dates or other staple food of the country. It is collected and given to some of the poor, or the whole amount is collected and given to some poor people, or some poor households, if she can afford it. But if she is poor, she does not have to feed anyone; rather, she only has to fast, along with repentance.
