Ramadan is the ninth month of the Islamic lunar calendar and the month in which fasting (Sawm) becomes obligatory on every adult, sane, and healthy Muslim. But beyond simply “not eating,” Ramadan comes with a complete set of rules—covering who must fast, what breaks the fast, who is exempt, and how to properly observe the month according to the Quran and Sunnah.

Rule 1: Who Must Fast in Ramadan
Fasting during Ramadan is obligatory on every Muslim who is:
- An adult (having reached puberty)
- Of sound mind
- Physically healthy and able to fast
- Not traveling (a long journey qualifies for exemption)
- Not menstruating or experiencing postnatal bleeding (for women)
Allah says in the Quran:
يَا أَيُّهَا الَّذِينَ آمَنُوا كُتِبَ عَلَيْكُمُ الصِّيَامُ كَمَا كُتِبَ عَلَى الَّذِينَ مِنْ قَبْلِكُمْ لَعَلَّكُمْ تَتَّقُونَ
Transliteration: Ya ayyuhal-ladheena amanu kutiba ‘alaykumus-siyamu kama kutiba ‘alal-ladheena min qablikum la’allakum tattaqoon.
Translation: “O you who believe! Fasting is prescribed for you, as it was prescribed for those before you, so that you may become righteous.” (Surah Al-Baqarah 2:183)
Rule 2: The Fasting Hours—From Fajr to Maghrib
A valid fast begins at Fajr (dawn, when the pre-dawn meal/Suhoor must end) and continues until Maghrib (sunset, when the fast is broken with Iftar). During these hours, a fasting Muslim must abstain completely from food, drink, and marital relations.
Rule 3: Who Is Exempt from Fasting
Islam is a religion of ease, and several categories of people are exempted from fasting, though most are required to make up the missed days later (Qada) or pay compensation (Fidya):
| Category | Ruling |
|---|---|
| Children (pre-puberty) | Not obligated to fast |
| The chronically ill/elderly unable to fast | Exempt—must pay Fidya (feed a poor person) instead |
| Temporarily sick (recoverable illness) | Exempt during illness—must make up missed days (Qada) later |
| Travelers on a genuine journey | May break fast—must make up missed days later. |
| Pregnant or breastfeeding women | Exempt if fasting risks their health or the child’s—make up days later |
| Menstruating women / postnatal bleeding | Fasting is not valid during this time—you must make up missed days later. |
Allah says regarding this ease:
فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ ۗ وَعَلَى الَّذِينَ يُطِيقُونَهُ فِدْيَةٌ طَعَامُ مِسْكِينٍ
Translation: “But whoever among you is ill or on a journey, then an equal number of days [are to be made up]. And upon those who can afford it is a ransom: the feeding of a poor person [for each missed day].” (Surah Al-Baqarah 2:184)
Rule 4: What Breaks the Fast
| Action | Breaks the Fast? |
|---|---|
| Eating or drinking intentionally | Yes. |
| Smoking | Yes. |
| Intentional vomiting | Yes. |
| Marital/sexual relations | Yes. |
| Menstruation or postnatal bleeding starting | Yes (fast becomes invalid). |
| Eating or drinking by mistake (forgetting you’re fasting) | No—the fast remains valid (Prophetic mercy). |
| Swallowing saliva | No |
| Brushing teeth carefully (without swallowing water/paste) | No (though some scholars advise caution) |
| Unintentional vomiting | No |
| An injection that is not for nutrition (e.g., medicine) | No, according to most scholars |
The Prophet ﷺ said regarding one who eats or drinks forgetfully:
“Whoever forgets that he is fasting and eats or drinks should complete his fast, for it is Allah who has fed him and given him drink.” (Sahih al-Bukhari 1933, Sahih Muslim 1155)
Rule 5: Suhoor and Iftar—The Two Essential Meals
Suhoor is the pre-dawn meal eaten before the Fajr fast begins. The Prophet ﷺ encouraged it, saying: “Eat Suhoor, for in Suhoor there is blessing (barakah).” (Sahih al-Bukhari 1923)
Iftar is the meal eaten to break the fast immediately at sunset (Maghrib). It is a Sunnah to break the fast promptly rather than delay it, traditionally with dates and water, following the Prophet’s ﷺ’ own practice.
Rule 6: Night Prayers and Increased Worship
Ramadan is also a month of heightened worship:
- Taraweeh—the special congregational night prayers performed after Isha throughout Ramadan
- Increased Quran recitation—many Muslims aim to complete a full reading of the Quran during the month
- Laylat al-Qadr—the “Night of Power,” believed to fall in the last ten nights (most likely on one of the odd nights), when the Quran was first revealed, and worship on this night is described as better than a thousand months (Surah Al-Qadr 97:3)
- I’tikaf—some Muslims observe spiritual retreat in the mosque, especially during the last ten days
Rule 7: Zakat al-Fitr Before Eid
Before the month ends, every Muslim (or the head of household on behalf of dependents) is required to pay Zakat al-Fitr, a small obligatory charity given in the form of food or its monetary equivalent, ideally before Eid al-Fitr prayer, so that the poor can also celebrate Eid without need.

Frequently Asked Questions
What are the basic rules of fasting in Ramadan? The basic rule is to abstain from food, drink, smoking, and marital relations from Fajr until Maghrib, with the sincere intention (niyyah) of fasting for the sake of Allah.
Who is exempt from fasting in Ramadan? Children, the chronically ill, the elderly who cannot fast, travelers, pregnant or breastfeeding women (if health is a concern), and menstruating women are all exempt, though most must make up the missed days later or pay Fidya.
What breaks a fast in Ramadan? Intentionally eating, drinking, smoking, vomiting on purpose, or engaging in marital relations during fasting hours breaks the fast. Accidentally eating or drinking due to forgetfulness does not invalidate it.
Can I brush my teeth while fasting? Yes, brushing teeth is generally permitted, though care should be taken not to swallow water, toothpaste, or saliva excessively. Many scholars recommend using a miswak or dry brushing as the safest option.
What happens if I miss a fast in Ramadan? If you miss a fast due to illness, travel, or menstruation, you are required to make up the missed day (Qada) after Ramadan, before the next Ramadan begins. Those permanently unable to fast pay Fidya instead.
Is it compulsory to pray Taraweeh in Ramadan? No, Taraweeh is a highly recommended Sunnah, not an obligatory (Fard) prayer, but it is strongly encouraged throughout the month, especially in congregation.
Conclusion
The rules of Ramadan are designed with both discipline and mercy—fasting is obligatory, but Allah has built in clear exemptions and alternatives for those who genuinely cannot fast. Understanding these rules helps every Muslim fast correctly, make up missed days properly, and make the most of this blessed month through Suhoor, Iftar, night prayers, and sincere worship.
May Allah accept our fasts and grant us the full blessings of Ramadan.
