Fasting in Islam during the month of Ramadan is one of the five pillars of Islam. It is an act of worship that carries immense spiritual reward, purification of the soul, and obedience to Allah’s command. Millions of Muslims around the world observe the fast every year, refraining from food, drink, and other invalidators of fasting from Fajr (dawn) until Maghrib (sunset). Despite its widespread observance, there are many points of confusion and common mistakes regarding what actions actually break the fast. Understanding exactly what nullifies one’s fast is essential to ensure that a person’s worship is valid and rewarded.
This comprehensive guide will explain what breaks the fast, highlight subtle situations that people often misunderstand, and clarify answers based on the Qur’an and Sunnah. Whether you are a new Muslim or seeking to perfect your worship, this article will help you avoid common pitfalls and strengthen your devotion during Ramadan and beyond.
1. What Is Fasting in Islam? A Brief Overview
Fasting, in Islamic terminology, is defined as abstaining from food, drink, and sexual relations from dawn (Fajr) until sunset (Maghrib) with the intention (niyyah) to fast for the sake of Allah. This definition is rooted in the Prophet Muhammad’s ﷺ explanation:
“Islam is built on five (pillars): testimony that there is no deity worthy of worship except Allah and that Muhammad is the Messenger of Allah; establishing prayer; paying Zakah; fasting Ramadan; and pilgrimage to the House (Hajj).”
(Bukhari and Muslim)
Fasting is both physical and spiritual. Physically, it involves sensory restraint from eating and drinking. Spiritually, it is a means to develop taqwa (God-consciousness), patience, gratitude, and self-discipline.
2. The Essentials of a Valid Fast
To understand what breaks the fast, we must first understand what establishes a valid fast:
a. Intention (Niyyah)
The fast is not valid without intention. A Muslim must form the intention each night before dawn to fast the next day. The intention does not need to be spoken aloud; it is a silent determination in the heart.

The Prophet ﷺ said:
“Actions are according to intentions…”
(Bukhari and Muslim)
b. Timeframe
The fast begins at Fajr (dawn) and ends at Maghrib (sunset). Eating or drinking after Fajr or before Maghrib, even in small amounts, is considered breaking the fast.
3. The Clear Things That Definitely Break the Fast
Certain acts unquestionably invalidate a fast based on authentic evidence:
1. Eating or Drinking Intentionally
Whether it’s a morsel of food, water, juice, or anything else — if a person intentionally consumes it after Fajr and before Maghrib, the fast is invalid and must be made up (qada).
The Messenger of Allah ﷺ said:
“Whoever eats or drinks during Ramadan deliberately, then let him complete his fast, and let him give up food and drink.”
(Bukhari)
2. Sexual Intercourse
Engaging in sexual relations during the daylight hours of Ramadan immediately breaks the fast and incurs expiation (kaffarah), which is a serious obligation.
3. Menstruation (Haydh) or Post-natal Bleeding (Nifas)
Women who begin menstruation or experience postnatal bleeding during the day of Ramadan must stop fasting. Their fast is not valid for that day and must be made up later.
The Prophet ﷺ said:
“Do not fast when you are menstruating, and do not pray.”
(Bukhari and Muslim)
4. Deliberately Vomiting
If a person deliberately induces vomiting during the day of fasting, this invalidates the fast.
However, vomiting unintentionally or due to illness does not break the fast.
5. Erection and Ejaculation from a Sexual Act
If a man experiences ejaculation as a result of sexual contact (even without penetration), the fast is invalid.

If ejaculation happens due to a dream (wet dream), the fast remains valid.
4. Common Mistakes Muslims Make: What People Think Breaks the Fast but Doesn’t
There are many misconceptions about what invalidates fasting. These include actions that people incorrectly believe break the fast.
1. Brushing Teeth Without Swallowing Toothpaste
Some people avoid brushing teeth during Ramadan out of fear of breaking the fast. This is a misconception.
If a person brushes without swallowing toothpaste, the fast remains valid. Scholars also encourage using Miswak (tooth stick) which was the practice of the Prophet ﷺ during Ramadan, especially before prayer and ablution.
2. Wetting the Throat While Rinsing Mouth or Nasal Passages
When performing wudu or cleaning the nose for prayer, water may accidentally enter the throat. If this happens unintentionally, the fast is not broken.
However, one should be cautious not to “rinse vigorously” with the intention of cleaning the throat, as that may risk invalidating the fast.
3. Bloodletting or Leeching
Many scholars state that phlebotomy or blood removed by leeches does not break the fast because it is not food or drink entering the body, and it does not provide nourishment.
4. Injections Given for Health Purposes
Most injections — even if they contain nutrients or glucose — do not break the fast if they are not taken for nourishment. Medical injections do not constitute eating or drinking because they bypass the mouth and digestive system.

However, intravenous fluids or nutritional drips may break the fast if they are used for nourishment. Scholars advise patients to consult knowledgeable scholars and their doctors when in doubt.
5. Smoking Food Smoke or Inhaling Vapour Without Intention
There is scholarly debate on inhaling smoke or vapour (e.g., from medical inhalers). If the vapour reaches the throat and enters the body with the intention of nourishment, some scholars regard it as breaking the fast. If it does not reach the throat, the fast remains valid.
The safe approach is to avoid smoking during the fasting hours, both for health and spiritual reasons.
6. Losing Consciousness
If a person faints or is unconscious during the fasting hours without swallowing anything, their fast remains valid. Illness or unconsciousness does not break a fast unless food or drink is taken.
5. Subtle Acts That May Break the Fast
Beyond the obvious invalidators, there are subtle actions that some Muslims unintentionally perform, thinking they are harmless.
1. Deliberately Swallowing Saliva
Some people think that swallowing excessive saliva invalidates the fast. This is not true. Whether a person intentionally or unintentionally swallows saliva, the fast remains valid.
2. Taking Medication with Water
Taking pills with water can break the fast due to the water. Therefore, if medication must be taken during fasting hours, it is best to plan around the fasting window or consult a scholar and doctor about alternatives.
3. Chewing Gum Without Swallowing
Although it may seem insignificant, chewing gum is considered consumption. If any flavourful substance enters the body as a result, the fast is invalid.
4. Using Flavoured Toothpaste
If toothpaste is used and accidentally swallowed, it may break the fast. Use of regular toothpaste should be done carefully, or prefer Miswak to be on the safe side.
5. Eating or Drinking Out of Forgetfulness
If a fasting person forgets and eats or drinks, this does not break the fast. This is based on the authentic hadith:
“If one of you forgets while he is fasting, and eats or drinks, then let him complete his fast, for it is Allah Who has fed him and given him to drink.”
(Bukhari and Muslim)
This is a mercy from Allah — the fast remains valid because the act was unintentional.
6. Actions That Do Not Break the Fast
Many acts commonly associated with invalidating the fast actually do not break it:
1. Taking a Bath
Whether minor (ghusl al-janabah) or ritual purification, bathing does not break the fast.
2. Applying Ointments or Lotions
External applications, such as skincare products, do not invalidate the fast unless they are nutritional substances swallowed accidentally.
3. Being Injected with Vaccines or Medicines
As explained earlier, most vaccinations and medicines do not break the fast as they are not considered food or drink.
4. Smoking Electronic Cigarettes (E-Cigarettes)
E-cigarette vapour is not food. However, scholars generally discourage vaping due to health risks and the principle of preserving one’s body. Still, the fast is considered valid if one uses it unintentionally.
5. Accidental Eating or Drinking
As clarified, accidental eating or drinking does not nullify the fast.
6. Unintended Physical Contact
Merely touching a spouse is not a reason to break the fast. It is sexual intercourse that breaks it, not simple physical contact.
7. Intending to Eat Without Swallowing
Planning or thinking about eating, without action, does not break the fast.
7. What About Medicines and Medical Emergencies?
There are situations where a fasting person needs medication. These require special consideration:
a. Pills Taken Without Water
If a patient consults a scholar and doctor, and the pill can be placed on the tongue and swallowed without water, many scholars permit this without breaking the fast.
b. Intravenous Fluids and Nutrition
If fluids are administered directly into the bloodstream for medical reasons, the fast may be broken, especially if for nourishment.
c. Insulin and Inhalers
There is a scholarly difference regarding insulin injections and inhalers. Many scholars say insulin does not break the fast because it is not food. Inhalers may be permissible if vapour does not reach the throat.
d. Emergencies
If a person’s health is at risk, preserving life is paramount in Islamic law. In such cases, breaking the fast is allowed and even required. The person should make up the fast later.
Allah says in the Qur’an:
“Allah intends for you ease and does not intend for you hardship…”
(Qur’an 2:185)
8. Sexual Relations and Expiation (Kaffarah)
If a person has sexual relations during fasting hours of Ramadan, the fast is invalidated and major expiation (kaffarah) is required, unless the person did so out of forgetfulness.
The Prophet ﷺ stated that the expiation for this is to:
Free a slave (historically), or if unable,
Fast for two consecutive months, or if unable,
Feed sixty poor people.
This underscores the gravity of violating the sanctity of the fast.
9. Menstruation and Fasting
Women who begin menstruating during Ramadan have a valid reason to stop fasting. Their fast is invalid for that day, and they must make it up after Ramadan.
Women should not fast if they are menstruating or bleeding post-childbirth. The fast during Haydh or Nifas is not accepted.
10. Frequently Asked Questions (FAQs)
Q1: Does swallowing saliva break the fast?
A: No. Saliva is not food or drink. The fast remains valid.

11. Wisdom Behind Fasting and Avoiding Invalidators
Fasting is not only about refraining from food and drink; it is a means to discipline the soul, restrain desires, and turn one’s attention to Allah.
Allah says in the Qur’an:
“O you who have believed, decreed upon you is fasting as it was decreed upon those before you, that you may attain taqwa.”
(Qur’an 2:183)
Abstaining from invalidators ensures sincerity in worship and protects the spiritual benefits of fasting.
12. Practical Tips to Avoid Mistakes
To ensure the fast remains valid:
✅ Begin the day with a clear intention (niyyah) before Fajr.
✅ Avoid eating or drinking after Fajr.
✅ Be mindful of toothpaste and mouth rinsing.
✅ Avoid smoking or vaping during fasting hours.
✅ Seek Islamic and medical guidance if on essential medication.
✅ Be cautious with mouth rinsing and nasal cleaning.
✅ If you forget and eat, continue your fast calmly.
13. Conclusion
The fast of Ramadan is a sacred act of worship, and understanding what breaks the fast ensures that one’s efforts are valid and rewarded. While there are clear invalidators like eating, drinking, and sexual intercourse, there are also many misconceptions about actions that people mistakenly believe break the fast.
With correct knowledge rooted in the Qur’an and Sunnah, Muslims can preserve their fasts, avoid common mistakes, and maximize the spiritual benefits of this blessed month. Whether it is brushing teeth, dealing with medical needs, or understanding unintentional acts, clarity leads to peace of mind and proper worship.
