Deliberately breaking a Ramadan fast without a valid excuse requires both making it up (qada) and expiation (kaffarah), while eating out of forgetfulness does not break the fast at all. Non-nutritive treatments such as injections, drops, and sprays do not break the fast according to the Diyanet. One of the most common questions in Ramadan is which situations break the fast and which leave it intact. This article sets out the standard that defines the boundary of the fast, the acts that do and do not invalidate it, the difference between making up a fast and expiation, and how modern treatments such as injections, sprays, and drops affect fasting — all grounded in reliable sources. ## The Meaning and Boundary of the Fast Literally meaning "to abstain from something, to restrain oneself," fasting (sawm) is defined in Islamic law as refraining, with a prior intention, from eating, drinking, and sexual relations from the break of dawn until sunset. As the Encyclopedia of Islam of the Turkish Religious Foundation (TDV) notes in its entry on fasting, the essential element of this worship is imsak — holding oneself back from these three things — while its condition is intention (niyyah). The question of whether a fast is broken therefore turns entirely on whether this boundary has been crossed. The prescription of fasting is stated clearly in the Qur'an: > O you who believe! Fasting is prescribed for you as it was prescribed for those before you, so that you may attain God-consciousness. Surah al-Baqarah, 183 The daily window of the fast is drawn just as precisely in the same surah — the night is open to eating and drinking, while the fast begins with dawn: > Eat and drink until the white thread of dawn becomes distinct to you from the black thread. Then complete the fast until nightfall. Surah al-Baqarah, 187 This measure is the key to understanding what does and does not break the fast: the heart of this worship is deliberately preventing anything from entering the body through these three channels, from dawn until the fast is broken at sunset. ## What Breaks the Fast By the agreement of Muslim scholars, the core acts that break the fast are eating, drinking, and sexual relations. Alongside these, any substance that reaches the stomach by way of the mouth or nose carries the same ruling. The Presidency of Religious Affairs (Diyanet) states that cigarettes, pipes, and similar substances also break the fast, since their smoke reaches the throat and stomach. Acts that break the fast, however, differ in the responsibility they entail — some require only making up the fast, while others require both making it up and expiation. ### Situations Requiring Only Qada (Making Up the Fast) In some cases the fast is broken, but the person owes only qada — making up that day later. This generally applies where the substance is not truly nourishing or pleasurable, or where intention and excuse are intertwined. For example, swallowing something with no nutritional value, deliberately swallowing rainwater or snow that enters the mouth, or unintentionally letting water slip down the throat during ablution are treated under this heading in Hanafi jurisprudence. In such cases only a single make-up fast is due. ### Situations Requiring Both Qada and Kaffarah (Expiation) Deliberately and knowingly breaking a Ramadan fast — without any religious excuse — by eating, drinking, or sexual relations requires both qada and kaffarah. This heavier responsibility follows from abandoning the worship intentionally and treating it lightly. > The difference between qada and kaffarah depends on the intention and conditions under which the fast was broken. A binding ruling for one's own case can only be determined by consulting a competent religious authority; this article is general information, not a fatwa. ## What Does Not Break the Fast At the head of the things that do not break the fast is eating or drinking out of forgetfulness. The Prophet (peace be upon him) reassured the believers plainly on this point: > Whoever forgets that he is fasting and eats or drinks, let him complete his fast, for it is Allah who fed him and gave him drink. Narrated by Abu Hurayrah and agreed upon by al-Bukhari and Muslim (muttafaq 'alayh), this authentic report shows that a bite eaten or a sip taken in forgetfulness does not break the fast, and that the person should continue fasting the moment he remembers. Other situations that do not break the fast include: - **Involuntary vomiting:** Vomiting that comes up on its own does not break the fast; deliberately vomiting a mouthful requires qada. - **Nocturnal emission and eye application:** Having a nocturnal emission while asleep, or applying kohl or eye drops, does not break the fast. - **Tasting:** Tasting food with the tongue to check its salt, without swallowing, does not break the fast. - **The miswak and dental care:** Brushing the teeth does not break the fast, as long as nothing is swallowed. - **Giving blood and fragrance:** Having blood drawn or applying a pleasant fragrance does not break the fast. > Backbiting, lying, and foul speech do not break the fast in a legal sense, but they erode its spiritual reward. In the Prophet's words, the true fast is that the tongue and the limbs abstain from sin along with the stomach. ## Medical Examinations and Treatments The possibilities of modern medicine have raised new questions about what breaks the fast. The High Board of Religious Affairs (Din İşleri Yüksek Kurulu) of the Diyanet sets the governing standard as follows: if what reaches the body is nourishing or pleasurable in nature, the fast is broken; if it serves only a treatment purpose and carries no nutritive quality, the fast is not broken. By this standard, the main medical applications that do **not** break the fast are: - Non-nutritive injections given for pain relief or immunity - Tablets placed under the tongue that pass directly into the bloodstream - Drops applied to the eyes, ears, and nose - Asthma inhalers (because the amount that reaches the body is very small) - Giving blood, receiving blood, biopsy, and angiography - Endoscopy and colonoscopy performed without administering nutritive fluids By contrast, the applications that **do** break the fast are those that supply the body with nourishment or fluids: - Injections that carry nutritional value - Intravenous serum and fluid supplements - General and regional anesthesia that involves serum - Enemas with nutritive content ## What Do Qada and Kaffarah Mean? Qada is making up, day for day after Ramadan, a fast that was missed or broken for any reason. Kaffarah is the heavier consequence of breaking a Ramadan fast deliberately and without excuse. Classical works of jurisprudence state that expiation is fulfilled, for one who is able, by fasting two consecutive months (sixty days); and for one unable to do so, by feeding sixty poor people. This severity is meant to guard against the worship being deliberately violated. ## When You Are in Doubt Many specific situations around fasting can carry different rulings depending on a person's health, intention, and exactly how the event occurred. For this reason, anyone in doubt should consult a competent religious authority such as the Diyanet for their own case. For the general framework of how to fast, you may read our [sermon on fasting](https://getvaaz.com/en/blog/sermon-on-fasting) and our [iftar and suhoor guide](https://getvaaz.com/en/blog/iftar-and-sahur-guide); for the context of the verses, see our [Qur'an](https://getvaaz.com/en/quran) section, and for the sources of the narrations, our [hadith](https://getvaaz.com/en/hadith) section. It should not be forgotten that the true aim of fasting, as stated in verse 183 of Surah al-Baqarah, is to reach taqwa — consciousness of one's responsibility before Allah. Knowing what does and does not break the fast is a framework that protects the fast kept with that consciousness. ## References 1.
