Fasting is a highly sacred act of worship in Islam, but even a small mistake or careless action can invalidate the fast. Muslims observe the fasts of Ramadan with devotion and happiness; however, they sometimes face situations that leave them uncertain about whether their fast has been broken or not.
In this guide, we will discuss what breaks a fast in Islam and what does not invalidate the fast, including modern-day scenarios. The goal is to provide clear and authentic guidance in one place, so our Muslim brothers and sisters can observe their fasts correctly and with confidence.
Things That Break Fast in Islam
The major actions that nullify or break the fast are as follows.
1. Eating or Drinking Intentionally
Any deliberate consumption of food or drink—no matter how small—breaks the fast. This includes every little action like eating, drinking, smoking, and chewing gum, etc.
Prophet Muhammad ﷺ said:
“Allah has relieved my Ummah from mistakes, forgetfulness, and what they are forced to do.”
(Ibn Majah 2045 – Hasan)
This Hadith illustrates that eating intentionally during the day breaks the fast, whereas eating forgetfully or by mistake does not invalidate it.
2. Sexual Intercourse During Fasting
Engaging in any form of marital relations during fasting hours will break the fast. The person involved in such acts must:
- Make up the fast (Qada)
- Offer expiation (Kaffarah)
3. Ejaculation Caused by Desire
If ejaculation occurs intentionally, either through sexual activity or masturbation (intentional stimulation), the fast is broken.
However, ejaculation resulting from unintentional wet dreams does not break the fast.
4. Intentional Vomiting
If a person deliberately induces vomiting, their fast will be nullified and he has to make it up later.
Prophet Muhammad ﷺ said:
“Whoever vomits unintentionally does not need to make up the fast, but whoever vomits intentionally must make it up.”
(Sunan Abu Dawood 2380 – Sahih)
5. Menstruation and Post-Natal Bleeding
If menstruation or post-natal bleeding begins during fasting hours, the fast becomes invalid. Missed fasts must be made up later.
The Prophet ﷺ said:
“Is it not true that when a woman menstruates, she neither prays nor fasts?”
(Sahih Bukhari 304)
6. Smoking or Vaping
Smoking introduces many substances into the body intentionally. Therefore, smoking (cigarettes, vape, or shisha) breaks the fast.
7. Taking Nutritional Medicines
Taking oral medications, IV fluids, or injections that provide nutrition will break your fast, because they introduce substances that nourish the body. On the other hand, non-nutritive treatments—such as insulin shots, vaccines, or other essential IM injections—do not invalidate the fast, allowing individuals to receive necessary medical care while still observing Ramadan.
Actions That Do NOT Break the Fast
Some actions are permissible in Islam and do not nullify the fast. These include:
- Forgetful eating or drinking
- Swallowing saliva
- Swallowing phlegm (unless it reaches the mouth and is swallowed deliberately)
- Blood tests
- Injections (non-nutritive)
- Tooth brushing with toothpaste or Miswak(without swallowing paste)
Conclusion
Understanding what breaks a fast in Islam is essential for every fasting Muslim. Islam provides clear guidance on things that break fast in Islam while also offering mercy for genuine mistakes.
By learning these acts that break fasting, believers can protect their worship, fast correctly, and gain the full spiritual reward of Ramadan.
May Allah accept our fasting, forgive our shortcomings, and grant us true taqwa. Ameen.
