Ruling on making up the prayer and fasting for one who died while ill

Question:
These are two questions sent by the sister (R. F. Y. L.) from Iraq. She says: My mother used to fast and pray, but she fell severely ill two years ago and passed away as a result. She did not fast or pray during her illness because she was unable to. Am I required to pay an expiation on her behalf, or to fast and pray on her behalf?
Please advise me, may Allah reward you.

Answer:
As long as she died while ill and unable to fast, you do not have to fast on her behalf. If she died in her illness and was unable to fast for a long period, then you do not make up anything on her behalf, and you do not have to feed anyone either, and praise be to Allah.
As for the prayer, she erred in leaving off the prayer. It was obligatory for her to pray, even if she was ill. One does not delay the prayer. It is obligatory for the sick person to pray according to his condition. If he can stand, he prays standing. If he is unable, he prays sitting. If he cannot sit, he prays on his right side—which is better—or on his left side, according to his capacity. If he cannot pray on his side, he prays lying down. This is how the Prophet (peace and blessings be upon him) commanded when some of the Companions (may Allah be pleased with them) complained to him of illness. He said to him: .
This is what is obligatory for the sick person, whether male or female: to pray sitting if he is unable to stand, whether sitting in a hunched position, in a cross-legged position, or as one sits between the two prostrations. All of this is permissible. If he is unable to sit, he prays on his right side or his left side, and the right side is better if he can. He intends the recitations and obligations of the prayer, and says what he is able to: he says the takbir, reads al-Fatihah first, reads what is easy for him, then says the takbir and intends the bowing. Then he says: "Allah hears the one who praises Him," intending the rising: "Our Lord, to You is praise," and so on. Then he says the takbir intending the prostration, and says: "Glory to my Lord, the Most High, Glory to my Lord, the Most High." Then he rises saying the takbir, intending the sitting between the two prostrations, and says: "Our Lord, forgive me, Our Lord, forgive me." Then he says the takbir intending the second prostration, and so on, with intention and speech according to his capacity.
The prayer is not made up; the prayer is not made up. Rather, it is upon you to make du'a for her, to send blessings upon her, and to seek forgiveness for her, if she was a monotheist, if she was a Muslim monotheist. But if she used to call upon the dead, seek aid from the dead and the graves, call upon other than Allah, then no du'a is made for her, because this is major shirk. If in her life she called upon the dead, sought aid from the dead, or from the people of the graves, or asked al-Badawi, or 'Abd al-Qadir, or other than 'Abd al-Qadir al-Jilani, this is from major shirk. Because calling upon the dead, and seeking aid from the dead, such as saying: "O my master 'Abd al-Qadir, cure my sick one," or "help me," or "heal me," or "O my master so-and-so—of the dead—do such-and-such for me," or "O Messenger of Allah, do such-and-such for me," or "O my master al-Badawi, do such-and-such," or "O so-and-so, do such-and-such," of the dead, all of this is from major shirk. And the one who dies in this state is not made du'a for, because he died upon the apparent shirk. We ask Allah for safety.
But if she was a monotheist, praise be to Allah, and did not call upon other than Allah, but worshipped Allah alone, then du'a is made for her, and forgiveness is sought for her, and no prayer is performed on her behalf, because the prayer is not made up. Yes.
