Hadith 30

Bulugh al-Maram

Book 5: Fasting
وَعَنْ عَائِشَةَ رَضِيَ اَللَّهُ عَنْهَا; أَنَّ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-قَالَ: { مَنْ مَاتَ وَعَلَيْهِ صِيَامٌ صَامَ عَنْهُ وَلِيُّهُ } مُتَّفَقٌ عَلَيْهِ 1‏ .‏
'A’isha (RAA) narrated that The Messenger of Allah (ﷺ) said:

"Whoever dies while he still has some fasts to make up (of the days of Ramadan), then his heir (any of them) should fast on his behalf.” Agreed upon.
