How to Fast in Islam (Sawm)

Fasting Ramadan is the fourth pillar of Islam. From the break of dawn until sunset you give up food, drink and intimacy, and you work on your character alongside it. Everything else about your day stays normal. See how it fits with the other pillars — salah stays five times a day through Ramadan too, see the full prayer guide if you need a refresher, and it is worth knowing your Zakat is calculated separately from this fast.

Dawn to Sunset Fourth Pillar of Islam Gratitude & Self-Control
🌅

Suhoor (Pre-Dawn Meal)

Eat before Fajr comes in. The sunnah is to leave it late rather than early, and even a sip of water counts as having taken it.

🌴

Breaking Fast with Dates

Break your fast as soon as Maghrib comes in, before you pray. Fresh dates if you have them, dried dates if not, and a few sips of water if there are no dates at all.

🌙

Iftar (Evening Meal)

The meal after Maghrib, usually shared with family or at the mosque. Feeding someone else who is fasting carries its own reward.

What Is the Daily Routine for Fasting?

1

Intention (Niyyah)

Decide in your heart, at some point during the night, that you are fasting tomorrow. For Ramadan this has to be settled before dawn breaks. There is nothing to say out loud.

2

Suhoor (Pre-Dawn Meal)

Eat and drink before Fajr comes in. Leaving it as late as you comfortably can is the sunnah, and there is blessing in the meal itself, so it is worth having even when you do not feel hungry.

3

Abstain Through the Day

From the moment Fajr begins until the Maghrib call, no food, drink, smoking or intimacy with your spouse. Everything else carries on as normal, including brushing your teeth and washing.

4

Mind Your Speech and Temper

The Prophet (peace be upon him) said that if someone insults you or picks a fight while you are fasting, you say "I am a person who is fasting" and leave it there. Lying, backbiting and arguing eat away at what you are meant to be building.

5

Iftar (Breaking the Fast)

Break it as soon as Maghrib comes in, before you pray, rather than waiting for the call to finish. Dates first if you have them, otherwise water. Then say:

Iftar Supplication: "Dhahaba adh-dhama'u, wabtallat al-'urooqu, wa thabata al-ajru in sha' Allah."
(The thirst is gone, the veins are moistened, and the reward is confirmed, God willing.)
Sunan Abu Dawud 2357, graded hasan

The dua of a fasting person right up to the moment they break their fast is one that God does not turn away, so ask for what you need before you eat.

What Breaks and Doesn't Break a Fast?

Invalidates Fast

What Breaks the Fast?

  • Eating or drinking on purpose: anything swallowed deliberately between Fajr and Maghrib.
  • Smoking: cigarettes, shisha or vape.
  • Intimacy with your spouse.
  • Making yourself vomit. Being sick involuntarily does not count.
  • Menstruation or postnatal bleeding: the fast ends the moment it starts, even if that is minutes before sunset.

Sexual intercourse is the serious one. On top of making the day up, it carries an expiation: fasting two consecutive months, or feeding sixty people in need if you genuinely cannot. Nothing else on this list carries that.

Allowed Practices

What Does Not Break the Fast?

  • Eating or drinking by mistake: if you forgot you were fasting, your fast is completely valid and there is nothing to make up.
  • Brushing your teeth or using a miswak, as long as you do not swallow.
  • Showering or swimming, and cooling off in water.
  • Injections, blood tests, eye and ear drops, and things that do not feed the body.
  • Rinsing your mouth and nose in wudu, gently rather than deeply.
  • Waking up needing a ghusl. You can wash after dawn and your fast still stands.

The Rule Behind the List

Something only breaks your fast if all three of these are true: you knew the ruling and that it was fasting hours, you remembered you were fasting, and you did it on purpose.

That is why the accidental mouthful is forgiven, and it is worth knowing before your first Ramadan. Most of what beginners panic about falls at one of those three.

If You Break It by Accident

Carry on fasting and finish the day as normal. There is nothing owed.

If you broke it deliberately without a valid reason, that is a serious matter: repent, and make the day up.

Who Is Exempt, and How Do You Make Up Missed Days?

Who Does Not Have to Fast?

Fasting is required of every Muslim who has reached puberty, is of sound mind, and is able. These are the excuses that lift it:

  • The sick, where fasting would genuinely harm you or set back your recovery. A cold or a headache does not count. If a doctor tells you fasting is dangerous, not fasting is the correct thing to do.
  • Travellers, on a real journey. You may fast if it is easy for you, and it is better if you can.
  • Pregnant or breastfeeding women, where there is a genuine fear for the mother or the baby.
  • Women who are menstruating or bleeding after childbirth. Fasting is not permitted, not merely excused.
  • The elderly and the permanently unwell, who cannot fast now and will not be able to later.

Heavy physical work is not on its own an exemption. Take suhoor, start the fast, and break it if real harm sets in.

Making Up Missed Days (Qada)

If your reason was temporary, you owe one day for each day missed. Travel, illness you recovered from, periods and pregnancy all fall here.

Two things people get wrong: They do not have to be consecutive. Fast them however suits you.
They should be done before the next Ramadan, so it is better not to leave them until the end.

Fidya (When You Cannot Make Them Up)

This is only for people who cannot fast now and will not be able to in future, such as the frail elderly or someone with a permanent condition. Instead of making days up, you feed someone in need.

The amount: One person fed for each day you missed, roughly half a saa' of a staple food such as rice, flour or dates. Most mosques and charities will take the cash equivalent and handle it.

A Note for Your First Ramadan

If you took shahada partway through the month, you fast from the day you became Muslim onwards. You do not owe the days before that.

Children are not obliged to fast until puberty, though many families let them try shorter days to get used to it.

What Voluntary Fasts Are There?

Recommended Sunnah Fasts

Outside Ramadan there are days the Prophet (peace be upon him) fasted regularly:

  • Mondays and Thursdays through the year.
  • The White Days: the 13th, 14th and 15th of each Islamic month.
  • Six days of Shawwal, the month straight after Ramadan.
  • The Day of Arafah, the 9th of Dhul Hijjah, for anyone not on Hajj — see Hajj if you're planning to go that year instead.
  • Ashura, the 10th of Muharram, together with the 9th.

Days You Must Not Fast

Enthusiasm is good, but some days are closed:

  • Eid al-Fitr and Eid al-Adha. Fasting either one is not allowed.
  • The three days after Eid al-Adha (11th, 12th and 13th of Dhul Hijjah).
  • Friday on its own is disliked. Pair it with the Thursday or the Saturday.

Health and Practical Tips

  • Drink steadily between Iftar and Suhoor rather than downing a litre at once.
  • Go easy on salty and fried food at Suhoor, or you will be thirsty by midday.
  • Oats, wholegrains and protein at Suhoor hold you far longer than sugar does.
  • If you become genuinely unwell during the day, break your fast and make the day up. That is the ruling, not a concession you talked yourself into.

Making the Most of Ramadan

The month is not only about going without. Read what Quran you can, pray at night in the last ten nights especially, give in charity, and feed someone else who is fasting.

If you are new to all of this, pick one of those and do it consistently rather than trying to do everything for three days and burning out.
