Before prescribing fasting in Islam, the Quraish tribe in the Jahiliya period used to fast on Ashura day as the Jewish fasted this day to thank Allah for rescuing Moses (AS) from drowning.
It’s noteworthy that Ashura sawm was obligatory for one year before binding Ramadan fasting.
What is the Purpose of Fasting in Islam?
The purpose of prescribing fasting in Islam is to train the believers to abstain from appetites, get used to patience and endurance, overcome bad habits obey Allah and seek his pleasure, and get closer to him.
Moreover, Fasting is a chance for Muslims to liberalize themselves from material slavery and learn how to manage their cravings.
Fasting in Ramadan is a spiritual worship that reminds Muslims of Allah’s blessings of food and drinks that they refrain from for over 8 hours a day in Ramadan.
What are the Virtues of Fasting in Islam?
Fasting in Islam carries many virtues for Muslims that tell you why it’s important in Islam. Here are the most significant benefits:
1. Entering paradise by fasting
Fasting in Islam is one of the reasons for rewarding with paradise. In the Hereafter, fast persons enter the Jannah through the gate of Al-Raiyan.
Sahl Ibn Saad (RA) reported that prophet Muhammed (PBUH) said:” There is a gate in Paradise called Ar-Raiyan, and those who observe fasts will enter through it on the Day of Resurrection and none except them will enter through it. It will be said, ‘Where are those who used to observe fasts?’ They will get up, and none except them will enter through it. After their entry, the gate will be closed, and nobody will enter through it.” (Sahih Bukhari)
2. Fasting provides Protection from the hell
One of the reasons for rescuing from the fire is fasting. Prophet Muhammed said:” Fasting is a shield or protection from the fire (Hell) and from committing sins” (Sahih Bukhari).
3. Forgiving from the sins
Allah rewards his believers who fast during Ramadan month with sins forgiveness. Abu Hurairah (RA) narrated that the Messenger of Allah said: “Whoever observes fasts during the month of Ramadan out of sincere faith and hoping to attain Allah’s rewards, then all his past sins will be forgiven.” (Sahih Bukhari).
4. Fasting is a way of answering the duas
The fasting person is among the believers that Allah answers their supplication. Prophet Muhammed said:” The fasting person when he breaks his fast, the just leader, and the supplication of the oppressed person” (Jami’ at-Tirmidhi).
5. Fasting is a great reward
Prophet Muhammed (PBUH) said:” The reward of every (good) deed of a person is multiplied from ten to seven hundred times”.
6. The mouth’s fasting person is better than musk
According to the prophetic narration, Prophet Muhammed (PBUH) said:” Verily, the smell of the mouth of a fasting person is better to Allah than the smell of musk.” [Al-Bukhari and Muslim]
7. A Joy for the fast person
Sawm carries joy for the fast person while breaking fasting, and another one when he meets Allah in the hereafter.
Prophet Muhammed (PBUH) said:” There are two joys for the fasting person: the joy when he breaks his fast, and the joy of when he meets his Lord.” [Al-Bukhari and Muslim]

The etiquette of breaking one’s fast, or iftar
Islamic tradition encourages breaking one’s fast promptly at sunset rather than delaying it unnecessarily, following the example of breaking fast with dates and water before proceeding to the sunset prayer and a fuller meal afterward. This practice balances spiritual discipline with practical wisdom, recognizing the body’s need for gentle, gradual refeeding after a full day without food or drink. Reciting the traditional supplication for breaking one’s fast adds a layer of gratitude and mindfulness to what might otherwise become a purely physical transition from hunger to satisfaction.
Making up missed fasts and expiation
Muslims who miss obligatory fasts due to valid reasons such as illness, travel, or menstruation are generally required to make up the missed days at a later time, known as qada, before the next Ramadan begins. In cases where a fast is deliberately broken without valid excuse, additional expiation, known as kaffara, may be required, which can involve fasting for an extended period or feeding a specified number of needy individuals. Understanding these provisions helps believers approach missed fasts with clear guidance rather than uncertainty about how to properly fulfill their obligation afterward.
The psychological and disciplinary benefits of fasting
Beyond its spiritual and physical dimensions, fasting cultivates significant psychological discipline, training practitioners to manage impulses, delay gratification, and maintain composure despite physical discomfort. This disciplined training extends naturally into other areas of life, helping fasting individuals develop greater self control over anger, harmful speech, and other behaviors the fasting period specifically encourages avoiding. Many practitioners report that the mental discipline built during structured fasting periods carries forward into improved habits and self awareness throughout the rest of the year.
Common misconceptions about fasting in Islam
- Fasting is sometimes mistakenly thought to be primarily about physical health rather than spiritual discipline and devotion, though both dimensions genuinely matter.
- Some assume fasting requires complete isolation from normal daily activities, when in fact most people continue working and studying as usual while fasting.
- Children are sometimes pressured into fasting before reaching an age of physical and spiritual readiness, though Islamic guidance generally encourages a gradual, supportive introduction.
Frequently asked questions about fasting in Islam
Can someone fast voluntarily outside of Ramadan without a specific occasion?
Yes, voluntary fasting on various days throughout the year, such as Mondays and Thursdays, is encouraged and carries additional spiritual reward beyond the obligatory Ramadan fast.
What happens if someone forgets they are fasting and eats accidentally?
Most scholars hold that accidentally eating or drinking while fasting due to genuine forgetfulness does not invalidate the fast, and the person should simply continue fasting once they remember.
Is it necessary to make a specific intention before each fast?
Yes, making an intention, even a simple internal one, before beginning each fast is generally considered a necessary condition for the fast to be valid.
Deepening your understanding of fasting in Islam
Understanding the full scope of fasting’s rulings, virtues, and practical application benefits greatly from structured, guided study. At Quran House, our Islamic studies courses help students explore the Quranic verses on fasting alongside their practical application, guided by instructors trained at Al-Azhar who can address specific questions with well grounded, nuanced answers. This structured approach helps students approach fasting with both confidence and genuine spiritual depth.
Fasting as a shared communal experience
Beyond its individual spiritual benefits, fasting during Ramadan creates a distinctive shared communal experience, as entire families, neighborhoods, and communities collectively adjust their daily rhythms around the fast, from shared pre dawn meals to communal iftar gatherings that break the fast together each evening. This collective dimension often strengthens social bonds and mutual support in ways that individual acts of worship do not, since the shared physical experience of hunger and the shared joy of breaking fast together create a sense of solidarity across an entire community. Many practitioners describe this communal aspect of fasting as one of its most cherished features, offering a yearly reminder of shared faith and mutual care within the broader Muslim community.
Final thoughts
Fasting in Islam combines physical discipline, spiritual devotion, and psychological growth into a single, comprehensive practice observed by Muslims worldwide. Understanding its proper etiquette, its provisions for missed fasts, and its broader benefits helps believers approach this pillar of faith with both practical clarity and genuine sincerity. Regular reflection on fasting’s deeper purpose, beyond mere abstention from food and drink, offers lasting spiritual and personal growth throughout the year.
