● If a person dies before having the opportunity to make up the missed fasts—such as someone whose excuse (e.g., illness) persisted until their death—then no makeup fast (qada), fidyah, or sin applies to them.

● However, if they had the ability to make up the fasts but did not do so before passing away, the missed fasts must be compensated by giving a mudd of food for each missed day from their estate.

The Prophet ﷺ said: "Whoever dies while having a month’s fast due, one needy person should be fed per day on their behalf." [Narrated by At-Tirmidhi]

Additionally, a guardian (wali) may fast on their behalf, as the Prophet ﷺ said: "Whoever dies while having missed fasts, their guardian should fast on their behalf." [Narrated by Al-Bukhari and Muslim]

In another narration: "If they wish." This indicates that both feeding the needy and fasting on behalf of the deceased are permissible options.

Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.

 

It is permissible to make up (qada’) missed prayers at any time, even during the periods when prayer is generally prohibited. The prayers that are forbidden and considered invalid during these times are 'absolute voluntary prayers' (nafl mutlaq)—which have no specific cause—and voluntary prayers whose cause follows the prayer itself, such as the Sunnah of entering Ihram or the Sunnah of the Istikharah prayer. Furthermore, no prayer is considered disliked (makruh) during these prohibited times when performed within the Meccan Sanctuary (Makkah al-Mukarramah).

 

It is stated in Bushra al-Karim (Vol.1/P.181), one of the Shafi’i texts: 'It is not forbidden to perform prayers that have a cause that is not delayed (i.e., the cause is preceding), such as making up a missed prayer (fa’itah)—even if it was a voluntary one—and the funeral prayer (janazah); or a cause that is simultaneous, such as the prayer for rain (istisqa’) or the eclipse prayer (kusuf)... and the Sunnah of wudu, the greeting of the mosque (tahiyyat al-masjid), the Sunnah of circumambulation (tawaf), the Sunnah of arrival, and the prostrations of recitation (tilawah) or thankfulness (shukr). These mentioned prayers and their like are not forbidden provided that one does not specifically intend (ta'ammud) to perform them during the disliked time because it is a disliked time. If one does so intentionally, it becomes forbidden, even if it is a mandatory makeup prayer that is due immediately; because in that case, one is acting in defiance of the Sharia. This is in contrast to when one does not specifically seek out that time, even if the prayer happens to fall within it, or if one seeks it for another purpose—such as delaying a funeral prayer to that time so that a larger number of people may pray over the deceased; in such cases, it is permissible and valid... And it is forbidden to perform prayers with no cause at all, like absolute nafl, or those with a delayed cause, such as the Istikharah prayer, the prayer for Ihram, the prayer for a need (hajah), the prayer before leaving the house, or the prayer before execution; because their causes occur after the prayer itself.' And Allah the Exalted knows best."
