sahih· Al-Albani

Narrated Ibn 'Abbas:

If a man falls ill during Ramadan and he dies, while he could not keep the fast, food will be provided (for the poor men) on his behalf ; there is no atonement (for his fasts) due from him. If there is some vow which he could not fulfill, his heir must atone on his behalf.

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ أَبِي حَصِينٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ إِذَا مَرِضَ الرَّجُلُ فِي رَمَضَانَ ثُمَّ مَاتَ وَلَمْ يَصُمْ أُطْعِمَ عَنْهُ وَلَمْ يَكُنْ عَلَيْهِ قَضَاءٌ وَإِنْ كَانَ عَلَيْهِ نَذْرٌ قَضَى عَنْهُ وَلِيُّهُ ‏.‏

Fasting the month of Ramadan is one of the pillars of Islam. It is mandatory for every adult Muslim who is a resident and physically able to fast. However, for the sick, the Shari`ah grants a concession: if the person recovers after Ramadan, they must make up the missed fasts, but if they cannot fast at all, then they must feed a poor person for each day missed.In this Hadith, `Abdullah ibn `Abbas (may Allah be pleased with him) said: “If a man falls ill during Ramadan” - i.e., with an illness that prevents him from fasting - “and then dies without having fasted,” meaning before making up for the missed fast, "food should be given on his behalf." That is, his guardian should feed a poor person for every missed day on his behalf, though there is no requirement for the guardian to fast on his behalf. However, if the deceased had made a vow to fast, then his guardian must fulfill this vow by fasting on his behalf. The guardian here refers to the `Asabah (closest male relatives responsible for fulfilling the deceased’s religious obligations), with the closest relative taking priority in fulfilling the obligation. The Hadith highlights the guardian's responsibility to fulfill expiations and vows on behalf of the deceased..
