sunnahfastHalf of loving the sunnah fasting days is knowing which days are not for fasting. The same Prophet ﷺ who taught us to fast Mondays and the White Days also marked out days when the fast is put down — days Allah made for eating, celebrating and family. Knowing them is not a technicality; it is part of the adab of fasting itself.
The two Eids
Eid al-Fitr and Eid al-Adha are the two feast days of the year, and fasting them is expressly forbidden:
“Narrated Abu Sa`id: The Prophet (ﷺ) forbade the fasting of `Id-ul-Fitr and `Id-ul-Adha (two feast days) and also the wearing of As-Samma' (a single garment covering the whole body), and sitting with one's leg drawn up while being wrapped in one garment. He also forbade the prayers after the Fajr (morning) and the `Asr (afternoon) prayers.”
The wisdom is beautiful: on the day the ummah celebrates together, nobody stands apart hungry. Eid is the day you answer the invitation of Allah — and you do not fast at a feast.
The days of Tashreeq
The three days after Eid al-Adha — the 11th, 12th and 13th of Dhul Hijjah, called the days of Tashreeq — carry the same ruling, in the Prophet’s ﷺ own words:
“Nubaisha al-Hudhali reported Allah's Messenger (ﷺ) as saying: The days of Tashriq are the days of eating and drinking.”
These are the days the pilgrims complete the rites of Hajj and everyone else enjoys the meat of the sacrifice. One practical consequence: in Dhul Hijjah the 13th — normally a White Day — falls inside Tashreeq, so that month only the 14th and 15th are fasted.
A Friday on its own
Friday is the best day of the week — which is exactly why it is not singled out for fasting, as if Jumuah needed improving:
“Narrated Abu Huraira: I heard the Prophet (ﷺ) saying, "None of you should fast on Friday unless he fasts a day before or after it."”
So a Friday fast is fine when it comes attached — a Thursday–Friday pair, or a Friday that happens to be a White Day or the Day of Arafah. What the sunnah discourages is picking Friday alone, as a fasting day in its own right. Jumuah has its own devotions: Surah al-Kahf, salawat and dua.
And Ramadan — a different kind of quiet
Ramadan is not on this list because fasting is forbidden — quite the opposite: the whole month is an obligatory fast, so there is simply no sunnah fast to remind you of. That is why sunnahfast goes silent for the month: you are already fasting, and the reminders would only be noise. The weekly Jumuah note still arrives (it never asks you to fast), and on the evening of Eid we return with the six days of Shawwal, Insha Allah.
How sunnahfast stays quiet for you
- No reminder is ever sent for the two Eids or the days of Tashreeq — those days are suppressed in the rules engine itself, not just left off a list.
- All of Ramadan is silent, and the White Days reminder in Dhul Hijjah automatically covers only the 14th and 15th.
- The Thursday-evening Jumuah note carries zero fasting language — it is about Kahf, salawat and the hour of acceptance.
- So if a nudge from us lands in your inbox, you can trust the day: it is a day the sunnah genuinely loves to see fasted.
