The ruling on making up Ramadan with expiation when the number of days is unknown

Question:
I have repented to Allah the Exalted, and praise be to Allah. However, before my repentance, I was negligent during the month of Ramadan. Two months passed in which I did not fast except for a few days, and this was when I reached the age of maturity. But now I am confused about the number of days I broke my fast, as I cannot count them. Does repentance wipe out what came before it, or am I required to make up the fasts along with something else in addition to making them up? May Allah reward you with good.

Answer:
Fasting is obligatory for the Muslim who has reached the age of maturity. If one leaves any of the days of Ramadan, it is obligatory for him to make them up, and his conscience is not cleared except by doing so, along with repentance to Allah, Glorified and Exalted is He. It is also obligatory for him, along with making up the fasts, to feed a poor person for each day as expiation for the delay in making up the fasts. This means feeding a poor person the amount of half a sa' (a dry measure of about 3 kg) for each day, along with repentance to Allah, Glorified and Exalted is He. As for the fact that you do not know the number of days, you must act based on estimation and precaution. You estimate the days and strive to estimate them, and you fast what you believe to be most likely the number you left. By doing this, your conscience is cleared, if Allah wills.
