Fasting (Sawm)
The rules of a valid fast, what breaks it, who is exempt, and how to make days up — beyond Ramadan alone.
What fasting is and who it applies to
Sawm means abstaining from food, drink and marital relations from true dawn (Fajr) until sunset (Maghrib), with the intention of worship.
- Fasting Ramadan is the fourth pillar of Islam and obligatory on every adult Muslim who is sane, resident and able.
- Children are encouraged gradually but are not obliged until puberty.
- The fast begins at true dawn, not at sunrise — stop eating when Fajr enters.
- Break the fast promptly at sunset; delaying it deliberately is against the sunnah.
Intention (niyyah) and suhoor
- For obligatory fasts the intention must be made during the night, before Fajr; it is made in the heart and need not be spoken.
- A single intention at the start of Ramadan is accepted by some scholars, but renewing it nightly is safest.
- For voluntary fasts the intention may be formed later in the day, provided nothing invalidating has occurred.
- Suhoor is a sunnah with blessing in it — even a sip of water counts.
What breaks the fast
These require making up the day (qada). Deliberate marital relations in Ramadan additionally require kaffarah.
- Eating or drinking deliberately, including smoking and vaping.
- Deliberate vomiting; unintentional vomiting does not break the fast.
- Marital relations during fasting hours.
- Nutritional injections or IV feeding; most scholars permit non-nutritional injections, insulin and vaccines.
- Menstruation or post-natal bleeding, even if it begins moments before sunset.
- Eating or drinking by genuine forgetfulness does NOT break the fast — continue fasting when you remember.
What does not break the fast
- Rinsing the mouth and nose in wudu, without exaggeration; using a miswak or unflavoured toothpaste carefully.
- Bathing, swimming, applying perfume, kohl, eye or ear drops (with differences of opinion on some drops).
- Blood tests and small blood draws; scholars differ on donating a large volume of blood or cupping.
- Unintentional swallowing of saliva, dust or the taste of food while cooking without swallowing it.
- Waking up in a state of janabah — perform ghusl and the fast remains valid.
Exemptions, qada and fidya
- The sick and travellers may postpone and make up the same number of days later (Quran 2:184–185).
- Menstruating and post-natal women do not fast and make up those days after Ramadan.
- Pregnant and breastfeeding women who fear harm may postpone; rulings on qada versus fidya differ by madhhab — ask a scholar.
- The permanently ill and the very elderly who cannot fast feed one needy person for each missed day (fidya).
- Missed days should ideally be made up before the next Ramadan.
Voluntary fasts
- Mondays and Thursdays — the days deeds are presented to Allah.
- The white days: the 13th, 14th and 15th of each Hijri month.
- ʿĀshūrāʾ (10th Muharram), preferably with the 9th, and ʿArafah for non-pilgrims.
- Six days of Shawwal after Ramadan — with Ramadan, like fasting the whole year (Muslim).
- Fasting is not permitted on the two Eid days.
