If you eat during Ramadan fasting hours, the consequences depend entirely on whether you did it on purpose or by accident. Eating forgetfully does not break your fast in most Islamic schools of thought, and you simply continue fasting as normal. Eating intentionally, however, invalidates the fast for that day and carries specific religious penalties.
Eating by Accident Does Not Break Your Fast
Forgetting you’re fasting and grabbing a snack or taking a sip of water is extremely common, especially in the first few days of Ramadan. The ruling on this is clear and widely agreed upon: your fast remains valid. A well-known hadith in Sahih al-Bukhari states, “If somebody eats or drinks forgetfully then he should complete his fast, for what he has eaten or drunk has been given to him by Allah.” The instruction is to simply stop eating the moment you remember and carry on with your day.
The mainstream Shafi’i position, as stated by Imam al-Nawawi, holds that this applies whether you ate a little or a lot while genuinely forgetful. A minority opinion within the same school argues that eating a large amount while supposedly forgetting is unusual enough to raise doubt, but this is not the dominant view. In practical terms, if you genuinely forgot you were fasting, you’re fine.
Eating Intentionally Invalidates the Fast
Deliberately eating or drinking during daylight hours breaks the fast for that day. This applies to food, water, smoking, vaping, or taking oral medication. Intentional vomiting and sexual intercourse during fasting hours also invalidate the fast, with intercourse carrying the most severe penalty.
If you intentionally break your fast without a valid excuse, you face two obligations. First, you must make up the missed day by fasting on a separate day after Ramadan ends. Second, for the most serious violations (particularly intentional intercourse), a penalty called kaffarah applies. Kaffarah requires one of the following: fasting for 60 consecutive days, or feeding 60 poor people. The severity of this penalty reflects how seriously Islamic law treats the deliberate violation of a Ramadan fast.
For someone who simply ate food intentionally, the requirement in most scholarly opinions is to make up that day (called qada). The kaffarah obligation for eating alone varies by school of thought, with the Hanafi school generally requiring it and others limiting it to intercourse.
Who Is Exempt From Fasting
Not everyone is required to fast during Ramadan, and eating during daylight hours is perfectly acceptable for those with valid exemptions. These include:
- Children who have not reached puberty
- Travelers on a journey
- Pregnant or breastfeeding women who believe fasting could harm themselves or their baby
- Women during menstruation or postnatal bleeding
- People who are ill when fasting would worsen their condition
- Elderly individuals who cannot physically tolerate fasting
- People with mental disabilities
Travelers and those with temporary illness are expected to make up missed days later. If an illness lasts all the way until the following Ramadan, the obligation to make up those days may be replaced by a charitable donation of food to a poor person for each missed day (roughly 750 grams of staple food like wheat or bread per day).
How Making Up Missed Days Works
Missed fasts should be made up before the next Ramadan arrives. You don’t have to do them consecutively; they can be spread across the year on days that work for you. If you had a valid excuse but then delay making up the fasts until the next Ramadan rolls around without good reason, some scholars hold that you owe both the makeup fast and a small charitable payment for each day you delayed.
If someone dies before they had a reasonable chance to make up their missed fasts, those fasts do not need to be compensated for. The obligation only applies when the person had enough healthy, non-exempt time to complete them and chose not to.
Gray Areas: Inhalers, Injections, and Medicine
Modern medical treatments create questions that didn’t exist in earlier centuries. Inhalers are one of the most debated. Since inhaled medication goes into the lungs rather than the stomach, some scholars consider it acceptable during fasting hours. Others argue that anything passing through the throat constitutes breaking the fast. There is no universal consensus, so many Muslim patients simply shift their inhaler doses to before dawn or after sunset to avoid the question entirely.
Injections and topical medications are another gray area. Many fasting Muslims avoid them during daylight hours even when scholars might permit them, simply out of caution. Medical guidelines for Ramadan generally recommend switching to once-daily or sustained-release medications taken during non-fasting hours, drinking 1 to 2 liters of fluid between sunset and dawn, and reducing intense physical activity during fasting hours.
Eating in Public During Ramadan
In some Muslim-majority countries, eating in public during Ramadan daylight hours carries legal or social consequences, even for non-Muslims. Saudi Arabia’s Interior Ministry has explicitly warned non-Muslim expatriates against eating, drinking, or smoking in public during fasting hours, with potential penalties including deportation. Similar restrictions exist in varying degrees in the UAE, Kuwait, and other Gulf states.
In countries without legal restrictions, eating in public is still considered disrespectful in communities with large Muslim populations. If you’re not fasting but live or work around people who are, eating discreetly rather than openly is a basic courtesy most people appreciate.
