Her mother did not perform fasting or prayer for a year before her death due to a mental disorder; is it obligatory to make up for her?

Question:
My mother (may Allah have mercy on her) fell ill before her death with a severe illness resulting from a severe fall on her head, which led to her suffering from a mental disorder for a full year. Therefore, she was unable to perform the two obligatory duties of fasting and prayer. I ask you to inform me whether I am required to make up the fasts for her, pay expiation, or perform any other action you can guide me to. May Allah preserve you and keep your steps steady, if it is in the manner that

Answer:
the questioner mentioned, since she is of unsound mind, she left off fasting because she is of unsound mind and lacking in awareness due to this injury. There is no fasting upon her and no obligation upon her, because she is of unsound mind, and obligation and worship are only required of a sane adult. So there is no fasting upon this afflicted woman who died from her affliction while being of unsound mind and lacking in awareness. However, if she had her mind and her awareness, but
the injury affected her until she died, then fasting is not dropped from her. If she has an estate, then expiation is paid from her estate by feeding one poor person for each day of the days she left off. If one of her relatives volunteers to feed on her behalf or fast on her behalf, it is hoped that that will benefit her. This is if she was not of unsound mind during the period in which she left off fasting. As for if she was of unsound mind and lacking in mind, then there is no fasting upon her. And Allah knows best. Yes.
