(41) باب فِيمَنْ مَاتَ وَعَلَيْهِ صِيَامٌ
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.
