Fasting on your period: why fasts are made up but prayers are not
Fasting and prayer are handled in opposite ways here: prayer is lifted and owed nothing, fasting is lifted but must be repaid. The asymmetry is not a later deduction — Aisha was asked about it directly.

No fasting, and a fast kept anyway does not count
A menstruating woman does not fast. If bleeding starts during a fasting day — even a minute before maghrib — that day’s fast is broken and must be made up.
The reverse case matters just as much: if bleeding stops during the night, she makes her intention and fasts. The fast is valid even if she performs ghusl after fajr — delaying ghusl affects prayer, not fasting, since she needs it before she can pray Fajr. Most scholars consider it better to complete ghusl before fajr.
Why one is repaid and the other is not
The same hadith settles both rulings at once:
That used to happen to us, and we were ordered to make up the fast, and were not ordered to make up the prayer.
— Aisha, Sahih Muslim 335
Scholars usually explain the wisdom this way: prayer recurs five times daily, so one cycle means twenty or thirty prayers, which would be a crushing repayment; fasting comes one month a year, which is repayable. But the ruling rests on the text — the reasoning is commentary on it.
How long you have
Missed fasts should be repaid before the next Ramadan arrives. Aisha said she would often not make hers up until Sha‘ban — understood to mean delay is permitted, delay past the next Ramadan is not.
The days need not be consecutive. All four schools agree they can be spread out.
If you miss the next Ramadan
| School | Position |
|---|---|
| Hanafi | Make up the fasts only. No fidya. |
| Maliki | Make up the fasts, plus fidya — feeding one poor person per day. |
| Shafi‘i | Make up the fasts, plus fidya; the common position compounds it per year missed. |
| Hanbali | Make up the fasts, plus fidya. |
If the delay was outside her control — ongoing illness, back-to-back pregnancies and nursing — most scholars hold that no fidya is owed for the delay itself. The fasts are still made up.
Period days never convert into fidya
A common misunderstanding: that missed days can simply be paid off with charity. They cannot. Someone able to fast repays fasts with fasts. Fidya appears in only two places: permanent inability to fast (advanced age, an irreversible illness), and — per the schools above — unexcused delay past the next Ramadan.
Pregnancy and nursing are a genuinely different case with a real three-way split among scholars: Fasting while pregnant or breastfeeding
What these days in Ramadan are actually for
Not fasting and not praying does not cut these days out of Ramadan. Tarawih is not prayed, but staying up, dhikr, du‘a, sadaqah, preparing iftar, caring for the household — all of it stands. Laylat al-Qadr falling in these days is the question that comes up most: istighfar and du‘a are entirely unrestricted, and that is precisely what the night is for.
