He died before making up for some days of Ramadan he missed to fast

Q 4: My father was ill and died while he had to make up for two days of Ramadan, This was a year ago. He passed away in Shawwal and he said that he would feed poor people to make up for the two days. What is obligatory on us regarding him? Should we fast and feed poor people or only feed poor people on his behalf? It is noted that we do not know whether he fed poor people to make up for these days or he fasted them. (Part No. 9; Page No. 262) He was a diabetic and he fasted Ramadan but with great difficulty.

A: If your father was able to make up for the missed days of fasting of the previous Ramadan but he was careless until another Ramadan came, after which he passed away, it is better that someone makes up for these two days. The Prophet (peace be upon him) said, If anyone dies in a state (that he had to complete) some days of fasting, his heir must fast on his behalf. (Agreed upon by Al-Bukhari and Muslim) Nevertheless, it is sufficient to feed poor people on his behalf a Sa` (1 Sa`=3 kg. Approx.) of the staple food of the country.If he was not able to make up for these days before the next Ramadan because of his illness, then neither feeding nor fasting is required because he was not careless.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
