She was ill for two years, so she did not pray and did not fast, and no one fed on her behalf, then she died. What is obligatory for us now?

Question:
I had a grandmother (may Allah have mercy on her) who passed away a year and a half ago. She was ill for a period of two years, and she did not pray, did not fast, and my father and my uncle did not feed on her behalf during the month of Ramadan when she was not fasting. We knew that this illness had occurred to her several years before Ramadan, and she did not make up the fasts, and no one fed on her behalf, and that was due to ignorance. So what must her parents do now? Please guide us. May Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and all his Companions. As for this woman mentioned, if she left off the prayer and fasting while her consciousness was gone, and she had no consciousness due to the illness, then she owes nothing, because she is not accountable in this state, because accountability is only with the presence of intellect and thought. So if the consciousness is gone, then she owes no prayer and no fasting. The Messenger (peace and blessings be upon him) said: The pen is lifted from three: the child until he reaches puberty, the insane person until he regains his sanity, and the sleeper until he wakes up. But if she had her consciousness, and she left off the prayer, and she understood it and was aware of it, then she erred in this. But when she died, the prayer is not made up on her behalf, because no one prays on behalf of another, and she neglected this. But perhaps she is excused by her ignorance, and perhaps Allah will accept her repentance because of her ignorance.
As for the fasting, if she has an estate, and she left off fasting while she had her consciousness and her intellect, but she was unable to fast due to the illness, then one poor person is fed on her behalf for every day from her estate, if she has an estate. And if she does not have an estate, and someone wants to give charity on her behalf, feeding one poor person for every day, then that is sufficient, if Allah wills. If the illness continued with her until she died, then she owes nothing, neither feeding nor making up the fasts. But if she recovered and was able to make up the fasts, and she delayed and did not make them up until she died, then she is the one for whom feeding is done, as we mentioned in the answer. Yes. May Allah reward you with good, and may Allah reward you.
