Making up the prayer and fasting for a deceased sick person

Question:
Peace, mercy, and blessings of Allah be upon you. I have a brother who is seventy years old. He suffered from a mental condition and was bedridden, unable to perform the obligatory prayers. He has passed away, and he was unable to fast the years he was afflicted with his condition. Do his children owe an expiation or anything else?

Answer:
As for the prayer, its matter ended with his death, and no one prays on behalf of another. However, he erred in not praying according to his condition. The Prophet (peace and blessings be upon him) said that the sick person prays . If he cannot do so, he prays lying on his back, with his feet facing the qiblah. He prays according to his condition, performing whatever pillars and obligations of the prayer he is able to do.
But he abandoned the prayer while his mind and intellect were present. This is an error. However, since he was ignorant, we hope that Allah will forgive him and pardon him. As for the fasting, if you fast on his behalf, you have done well, because proxy is permitted in fasting. It is permissible. The Prophet (peace and blessings be upon him) said . Proxy is included in this hadith.
