In a Nutshell: Muslims fast during Ramadan because it is one of the five pillars of Islam, commanded directly by Allah in the Quran: "O you who believe, fasting has been prescribed for you as it was prescribed for those before you, that you may attain taqwa (God-consciousness)" (Quran 2:183).
During the ninth month of the Islamic lunar calendar, Muslims abstain from food, drink, smoking, and sexual relations from dawn (fajr) to sunset (maghrib) each day. The fast is not merely an exercise in self-denial but a comprehensive spiritual discipline designed to cultivate gratitude, empathy with the hungry, self-control, and closeness to God. Ramadan is also the month in which the Quran was first revealed, and Muslims increase their recitation, prayer, and charitable giving during this period. The month concludes with Eid al-Fitr, one of Islam's two major celebrations.
This article explores the Quranic and Prophetic foundations of fasting, the spiritual and ethical reasoning behind the practice, practical guidance for those observing the fast, and answers to the most common questions about Ramadan.
Introduction
Every year, approximately 1.9 billion Muslims around the world observe Ramadan. For an entire lunar month, they wake before dawn to eat a pre-fast meal (suhoor), abstain from all food and drink throughout the daylight hours, break their fast at sunset (iftar), and spend their evenings in additional prayer and Quran recitation. The practice spans every continent, every climate, and every social class. A taxi driver in Cairo, a surgeon in London, a student in Jakarta, and a farmer in Senegal all participate in the same fast, and the shared experience creates a sense of global community that is difficult to overstate.
For non-Muslims, Ramadan can appear extraordinary and perhaps baffling. Why would anyone voluntarily abstain from food and water for an entire month? Is it safe? Is it compulsory for everyone? What is the point? These are reasonable questions, and they deserve thoughtful answers.
For Muslims, Ramadan occupies a unique place in the religious calendar. It is the month in which the Quran was first revealed (Quran 2:185), the month in which the Night of Power (Laylat al-Qadr), described in the Quran as "better than a thousand months" (Quran 97:3), occurs, and the month in which the rewards for good deeds are multiplied. It is a month of spiritual intensity in which the daily routine is restructured around worship, self-examination, and generosity.
This article examines the foundations of the Ramadan fast in the primary Islamic sources, analyses the spiritual and ethical wisdom behind the practice, provides practical guidance for those observing or learning about the fast, and addresses the questions most commonly asked by both Muslims and non-Muslims.

Quranic Verses
"O you who believe, fasting has been prescribed for you as it was prescribed for those before you, that you may attain taqwa." (Quran 2:183)
"The month of Ramadan in which the Quran was revealed, a guidance for the people and clear proofs of guidance and criterion. So whoever sights the new moon of the month, let him fast it; and whoever is ill or on a journey, then an equal number of other days." (Quran 2:185)
"It has been made permissible for you the night preceding fasting to go to your wives. They are a garment for you and you are a garment for them. Allah knows that you used to deceive yourselves, so He accepted your repentance and forgave you. So now have relations with them and seek what Allah has decreed for you. And eat and drink until the white thread of dawn becomes distinct to you from the black thread of night. Then complete the fast until sunset." (Quran 2:187)
"Indeed, We sent it down during the Night of Power. And what can make you know what the Night of Power is? The Night of Power is better than a thousand months." (Quran 97:1 to 3)
"And when My servants ask you concerning Me, indeed I am near. I respond to the invocation of the supplicant when he calls upon Me." (Quran 2:186) This verse appears in the middle of the verses about Ramadan, and scholars have noted its placement as indicating that the fasting month is a time of particular divine closeness and responsiveness to prayer.
Hadiths
The Prophet (pbuh) said: "Islam is built upon five pillars: testifying that there is no god but Allah and that Muhammad is the Messenger of Allah, establishing the prayer, paying zakat, performing Hajj, and fasting Ramadan." (Sahih al-Bukhari and Sahih Muslim)
The Prophet (pbuh) said: "When the month of Ramadan begins, the gates of heaven are opened, the gates of Hell are closed, and the devils are chained." (Sahih al-Bukhari and Sahih Muslim)
The Prophet (pbuh) said: "Whoever fasts Ramadan out of faith and seeking reward from Allah, his previous sins will be forgiven." (Sahih al-Bukhari and Sahih Muslim)
The Prophet (pbuh) said: "Fasting is a shield. When one of you is fasting, let him not speak obscenely or act ignorantly. If anyone insults him or tries to quarrel with him, let him say: I am fasting, I am fasting." (Sahih al-Bukhari and Sahih Muslim)
The Prophet (pbuh) said, reporting from Allah (hadith qudsi): "Every deed of the son of Adam is for himself except fasting; it is for Me and I shall reward it." (Sahih al-Bukhari and Sahih Muslim) This extraordinary hadith sets fasting apart from all other acts of worship by attributing its reward directly and exclusively to God.
The Prophet (pbuh) said: "Whoever does not give up false speech and acting upon it, Allah has no need of his giving up food and drink." (Sahih al-Bukhari)
Companions' Opinions
Abdullah ibn Umar (ra) was known for his meticulous observance of the Ramadan fast and for his generosity during the month, increasing his charitable giving significantly. He understood the fast as inseparable from a broader ethic of selflessness and community service.
Aisha (ra) reported that the Prophet (pbuh) would intensify his worship during the last ten nights of Ramadan to a degree not seen at any other time of the year. He would "tighten his belt" (a metaphor for redoubling his effort), pray throughout the night, and wake his family to join him. This practice of i'tikaf (spiritual retreat in the mosque) during the final ten nights remains widely observed.
Abu Hurairah (ra) narrated more hadiths about Ramadan than any other companion, reflecting the centrality of the month in his understanding of Islam. He reported the Prophet's words about the gates of heaven opening and the devils being chained, establishing the theological framework within which Muslims experience the month.
Traditional Scholars' Quotes
Al-Ghazali (11th to 12th century): In "Ihya Ulum al-Din," al-Ghazali described three levels of fasting. The first is the fast of the common person (sawm al-'umum), which involves abstaining from food, drink, and sexual relations. The second is the fast of the select (sawm al-khusus), which additionally involves guarding the eyes, tongue, ears, hands, and feet from sin. The third is the fast of the elect of the elect (sawm khusus al-khusus), which is the fast of the heart from all worldly concerns and from everything other than God. Al-Ghazali argued that the physical fast is merely the outer shell of a spiritual discipline whose true purpose is the transformation of the heart.
Ibn al-Qayyim (14th century): In "Zad al-Ma'ad," Ibn al-Qayyim analysed the health benefits and spiritual wisdom of fasting, arguing that it serves the body, the soul, and the community simultaneously. He noted that fasting disciplines the appetites, sharpens the intellect, softens the heart towards the poor, and creates solidarity among believers.
Al-Nawawi (13th century): In "al-Majmu'," al-Nawawi compiled the detailed juristic rulings of the fast, including the conditions, exemptions, and invalidating factors, providing the technical framework that Muslims continue to rely upon.
Analysis: Why Do Muslims Fast During Ramadan?
The Quranic verse prescribing the fast states its purpose directly: "that you may attain taqwa" (Quran 2:183). Taqwa is among the most important concepts in the Quran, appearing in various forms over two hundred and fifty times. It is commonly translated as "God-consciousness," "piety," or "mindfulness of God," but none of these English words fully captures its meaning. Taqwa is the state of being constantly aware that God sees and knows everything, and of shaping one's behaviour accordingly. It is not fear in the paralysing sense but a vigilant, loving awareness that orients every action towards what is right. The Quran identifies the attainment of taqwa as the explicit purpose of fasting, which means that all the other dimensions of the fast, physical, social, ethical, and communal, serve this overarching spiritual goal.
The physical dimension of fasting is the most visible but the least important in terms of the tradition's own understanding. Abstaining from food and drink from dawn to sunset is demanding, particularly in the long summer days of northern latitudes where the fast may last eighteen hours or more. But the Prophet (pbuh) made clear that the physical deprivation is a means rather than an end: "Whoever does not give up false speech and acting upon it, Allah has no need of his giving up food and drink" (Sahih al-Bukhari). A person who abstains from food while gossiping, lying, cheating, or losing their temper has missed the point. The physical hunger is designed to create the conditions for a deeper spiritual and ethical transformation.
The ethical dimension of fasting is directly connected to empathy. A person who has never experienced hunger cannot fully understand what the poor endure daily. By experiencing hunger voluntarily, the fasting person develops a visceral, embodied understanding of what it means to go without. This is not merely sentimental; it is intended to translate into action. The Prophet (pbuh) was described as being "more generous than the wind" during Ramadan (Sahih al-Bukhari), and the tradition of increased charitable giving during the month, culminating in the obligatory zakat al-fitr (a charitable payment due before Eid) ensures that the empathy generated by fasting has concrete material expression.
The communal dimension of Ramadan is among its most distinctive features. Unlike most forms of worship, which can be practised individually, Ramadan creates a shared social experience. The entire community wakes together before dawn, fasts together through the day, breaks the fast together at sunset, and prays together in the evening. The iftar (meal at sunset) is often a communal event, with mosques, families, and community organisations hosting large gatherings. The tarawih prayers, special evening prayers performed only during Ramadan in which the entire Quran is recited over the course of the month, bring the community together nightly. This shared rhythm of sacrifice and celebration creates bonds of solidarity that extend across class, ethnicity, and geography.
The connection between Ramadan and the Quran is also fundamental. The Quran states that Ramadan is "the month in which the Quran was revealed" (Quran 2:185), and this connection shapes how the month is experienced. Muslims increase their engagement with the Quran during Ramadan, with many aiming to complete a full reading of the text during the month. The nightly tarawih prayers, in which the Quran is recited at length, serve as a communal encounter with the revealed text. The Night of Power (Laylat al-Qadr), which falls in the last ten nights of Ramadan and is described as "better than a thousand months" (Quran 97:3), commemorates the night on which the Quran was first revealed to the Prophet (pbuh) through the Angel Jibril (Gabriel).
Practical Guide to the Ramadan Fast
This section is intended for those who are new to fasting, whether new Muslims, non-Muslims participating in solidarity, or Muslims seeking a clear summary of the practical requirements.
The fast begins each day at fajr (the true dawn, when a faint light appears on the eastern horizon) and ends at maghrib (sunset). The precise times vary by location and change slightly each day. Muslims typically consult a local mosque timetable or a reliable prayer-time application for the exact times.
The pre-dawn meal, known as suhoor (also spelled sehri or sahur), is eaten before the fajr prayer. The Prophet (pbuh) encouraged eating suhoor, saying: "Take suhoor, for in suhoor there is blessing" (Sahih al-Bukhari and Sahih Muslim). A balanced suhoor typically includes complex carbohydrates, protein, and plenty of water. It is recommended to eat as close to the start of the fast as possible rather than eating early and going back to sleep.
During the fasting hours, a Muslim abstains from all food and drink (including water), smoking, and sexual relations. Unintentional consumption (such as forgetting one is fasting and eating by mistake) does not invalidate the fast, according to the hadith: "If somebody eats or drinks forgetfully, let him complete his fast, for it is Allah who fed him and gave him drink" (Sahih al-Bukhari and Sahih Muslim). Swallowing one's own saliva, using eye drops, receiving injections that are not nutritive, and brushing one's teeth (provided nothing is swallowed) are considered permissible by most scholars, though there is some scholarly variation on the details.
The fast is broken at sunset with the iftar. The Prophet (pbuh) used to break his fast with fresh dates and water before praying maghrib. If dates are not available, water is sufficient. It is recommended to break the fast promptly at sunset rather than delaying.
The fast is obligatory for every adult Muslim who is sane, healthy, and not travelling. Several categories of people are exempt. Those who are physically ill may defer their fast and make up the missed days later. Travellers may break their fast and make up the days afterwards. Pregnant and breastfeeding women may defer if fasting poses a risk to their health or that of their child, though scholars differ on whether they must make up the days, pay a fidyah (feeding a poor person for each day missed), or both. Women who are menstruating do not fast during their period and make up the missed days after Ramadan. Elderly people and those with chronic illnesses who cannot fast at all may pay fidyah instead. Children are not obligated to fast, though many families encourage children to practise partial fasting as they approach puberty.
The nightly tarawih prayers are a distinctive feature of Ramadan. They are performed after the isha (night) prayer, either individually at home or, more commonly, in congregation at the mosque. They typically last between one and two hours and involve the recitation of substantial portions of the Quran. They are classified as sunnah mu'akkadah (a strongly recommended practice) rather than obligatory.
The month concludes with Eid al-Fitr, the festival of breaking the fast. Before the Eid prayer, every Muslim who possesses more than their basic needs must pay zakat al-fitr, a charitable payment (typically the value of a meal) on behalf of every member of their household. The Eid prayer is performed in congregation, usually outdoors or in a large venue, and is followed by celebration, visiting family and friends, and the exchange of gifts.
5 Misconceptions about Fasting in Ramadan
"Fasting in Ramadan is just about not eating." The physical abstention from food and drink is only the most visible element. The fast also requires abstaining from gossip, lying, anger, and all forms of morally objectionable behaviour. The Prophet (pbuh) explicitly stated that a person who does not abandon false speech while fasting has gained nothing from their hunger. Al-Ghazali's three levels of fasting make clear that the physical fast is the entry point, not the destination.
"Fasting is dangerous and unhealthy." For the overwhelming majority of healthy adults, the Ramadan fast is not medically dangerous. Numerous clinical studies have found that intermittent fasting within the Ramadan pattern does not produce adverse health outcomes in healthy individuals and may carry certain metabolic benefits. Islam explicitly exempts those who are ill, elderly, pregnant, breastfeeding, or travelling, demonstrating that the shari'ah itself prioritises health and does not require anyone to fast at risk to their wellbeing.
"Muslims gorge themselves at iftar, so the fast is pointless." While it is true that some cultural practices around iftar involve elaborate meals, this is a cultural habit rather than a religious instruction. The Prophetic model was to break the fast simply with dates and water, to pray, and then to eat a moderate meal. Scholars consistently advise moderation at iftar and warn against excessive eating that defeats the purpose of the fast.
"Ramadan is a month of deprivation and misery." Most Muslims describe Ramadan as the highlight of the year. The communal iftars, the nightly prayers, the increased focus on Quran recitation, the atmosphere of generosity, and the shared sense of spiritual purpose create an experience that Muslims overwhelmingly associate with joy rather than suffering. The month concludes with Eid al-Fitr, one of Islam's two major celebrations.
"Non-Muslims must also fast in Muslim-majority countries." While some Muslim-majority countries have laws restricting public eating during Ramadan, these are matters of local legislation rather than Islamic jurisprudence. The Quran states clearly that "there is no compulsion in religion" (Quran 2:256), and classical scholars did not require non-Muslims to observe the fast. Many Muslims welcome non-Muslims to share iftar meals as a gesture of hospitality and friendship.
5 Objections Addressed Regarding the Ramadan Fast
"Is it not irrational to abstain from water in hot climates for up to eighteen hours?" The fast is demanding, and the Islamic tradition acknowledges this. The Quran describes fasting as involving "a fixed number of days" and provides exemptions for those who are ill or travelling (Quran 2:184). The difficulty of the fast is not incidental but is part of its purpose: it is through the experience of genuine discomfort that the spiritual and ethical benefits are realised. That said, Islam does not require anyone to endanger their health. Scholars consistently advise that a person who genuinely fears harm from fasting should break the fast and make up the day later.
"Why does the month move through the calendar? Does it not create unequal burdens?" The Islamic calendar is lunar, meaning that Ramadan moves approximately eleven days earlier each solar year, cycling through all seasons over a period of roughly thirty-three years. This means that Muslims in every part of the world experience both short winter fasts and long summer fasts over the course of their lifetime. The rotating calendar ensures that no latitude is permanently advantaged or disadvantaged. For Muslims living at extreme northern or southern latitudes where daylight hours become very long or very short, scholars have issued specific guidance, including the option of following the timetable of the nearest moderate latitude or of Makkah.
"Children should not be made to fast." Islam does not require children to fast before puberty. The tradition of encouraging children to practise partial fasting (such as fasting for half the day) is precisely that: encouragement, not obligation. The Prophet (pbuh) modelled a gradual approach to religious practice, and scholars unanimously hold that the obligation of fasting begins at puberty, not before.
"Fasting reduces productivity and is economically harmful." Research on the economic impact of Ramadan presents a mixed picture. Some studies have found modest reductions in productivity in certain sectors, while others have found no significant impact. Several Muslim-majority countries adjust working hours during Ramadan to accommodate the fast. The Islamic tradition does not consider economic productivity the ultimate measure of human activity: the purpose of the fast is spiritual and ethical development, which Muslims consider at least as valuable as economic output.
"Why should God care whether people eat or not?" The Islamic answer is that God does not need human fasting. The benefit of the fast accrues entirely to the one who fasts. As the hadith qudsi states, fasting is "for Me and I shall reward it," not because God requires the sacrifice but because the act of voluntary deprivation cultivates the qualities (gratitude, empathy, discipline, closeness to God) that Islam considers essential to human flourishing. The fast is a gift to the believer, not a tax demanded by God.
FAQs: Why Do Muslims Fast During Ramadan?
"What happens if you accidentally eat or drink while fasting?" If a person eats or drinks out of genuine forgetfulness, the fast remains valid and they simply continue fasting. The Prophet (pbuh) said: "If somebody eats or drinks forgetfully, let him complete his fast, for it is Allah who fed him and gave him drink" (Sahih al-Bukhari and Sahih Muslim). This ruling reflects Islam's emphasis on intention: sin requires deliberate choice.
"Can you brush your teeth while fasting?" The majority of scholars permit brushing teeth while fasting, provided that nothing is swallowed. The Prophet (pbuh) used a miswak (a natural toothbrush from the salvadora persica tree) during fasting. Some scholars advise caution with flavoured toothpaste, suggesting that a plain miswak or unflavoured toothpaste is preferable during fasting hours, but this is a matter of scholarly caution rather than a binding prohibition.
"What is Laylat al-Qadr and why is it significant?" Laylat al-Qadr (the Night of Power or Night of Decree) is the night on which the Quran was first revealed to the Prophet (pbuh). The Quran describes it as "better than a thousand months" (Quran 97:3), meaning that worship on this single night is more valuable than worship spread over more than eighty years. It falls on one of the odd-numbered nights in the last ten days of Ramadan (the 21st, 23rd, 25th, 27th, or 29th), and the Prophet (pbuh) encouraged Muslims to seek it by intensifying their worship throughout the last ten nights.
"Do Muslims in the Arctic, where the sun may not set, still have to fast?" Scholars have addressed this scenario with several approaches. The most widely followed opinion is that Muslims in regions of extreme daylight should follow the timetable of the nearest city with a distinguishable day and night cycle, or the timetable of Makkah or Madinah. The key principle is that the fast should be demanding but not impossible, and the shari'ah does not require what is beyond human capacity.
"What is zakat al-fitr and who must pay it?" Zakat al-fitr is a mandatory charitable payment due before the Eid al-Fitr prayer, payable by every Muslim who possesses more than their basic needs. It is paid on behalf of every member of the household, including children. Its purpose is twofold: to purify the fasting person from any shortcomings during Ramadan, and to ensure that the poor can also celebrate Eid. The amount is traditionally equivalent to one sa' (approximately 2.5 to 3 kilograms) of staple food, or its monetary equivalent.
Conclusion
The Ramadan fast is one of the most visible, most widely practised, and most deeply felt expressions of Islamic faith. Its foundations in the Quran and Sunnah are unambiguous, its purpose is clearly stated (the attainment of taqwa, or God-consciousness), and its practice has been continuous and universal across the Muslim world since the earliest generation.
What makes Ramadan distinctive is the way it integrates multiple dimensions of human experience into a single month-long discipline. It is physical, requiring genuine bodily sacrifice. It is spiritual, creating the conditions for heightened prayer, reflection, and encounter with the Quran. It is ethical, cultivating empathy, generosity, and self-control. And it is communal, binding Muslims together across every boundary of geography, culture, and class in a shared experience of voluntary hardship and collective celebration.
For those observing Ramadan, the hope is that the qualities cultivated during the month, patience, gratitude, generosity, closeness to God, and compassion for those in need, will endure long after the month itself has ended. For those learning about it, perhaps the most important thing to understand is that Muslims do not experience Ramadan as a burden. They experience it, overwhelmingly, as a gift.
