What do different faiths say about fasting?

In Islam, fasting is not a peripheral practice or a seasonal discipline that sits quietly on the edges of faith. It sits at the very centre. The fast of Ramadan is one of the Five Pillars, the foundational acts that structure a Muslim's life and relationship with God. For an entire lunar month, Muslims who are able abstain from food, drink, smoking and sexual relations from dawn until sunset. This is not simply about hunger or willpower. The Arabic word often used for this fast is "sawm," which carries the sense of restraint and holding back, and the tradition understands it as a whole-person act of worship, not just a bodily one.

The Quran addresses fasting directly, and the verses around Ramadan connect it explicitly to the concept of taqwa, a word often translated as "God-consciousness" or "piety" but which carries richer texture than either of those English words quite captures. Taqwa is something like a heightened awareness of God's presence and a genuine care about how one lives in response to that. The fast, in Islamic understanding, is designed to cultivate this. When you remove the ordinary satisfactions of the day, eating, drinking, the comfortable rhythms of daily life, you become more alert to your own inner state, your intentions, your dependencies, and ultimately your reliance on God. The tradition is clear that fasting is not only about the stomach. Alongside the physical fast, a person is expected to guard their tongue, avoid backbiting, resist anger, and be more generous. A person who fasts physically but behaves badly is, in classical Islamic teaching, missing the point.

The Prophet Muhammad, peace be upon him, is central to how Muslims understand the practice. The hadith literature, the collected sayings and actions attributed to the Prophet, gives rich detail about how fasting should be lived. He spoke of the spiritual rewards of Ramadan, of the particular significance of the night known as Laylat al-Qadr near the end of the month, and of the spirit in which fasting should be entered. There are also narrations in which he observed voluntary fasts outside Ramadan, such as fasting on Mondays and Thursdays or during certain months, and this has led to a developed tradition of supererogatory fasting that devout Muslims may choose to observe throughout the year. Ramadan is obligatory; these additional fasts are chosen acts of closeness to God.

One thing that strikes many people, including Muslims themselves when they reflect on it, is that Ramadan is deeply communal as well as deeply personal. The pre-dawn meal, called suhoor, and the breaking of the fast at sunset with iftar are shared experiences. Mosques fill up in Ramadan in ways they may not at other times. Families and communities gather. There is a warmth and solidarity to the month that many Muslims describe as incomparable. The fast creates a kind of collective vulnerability, everyone is hungry, everyone is waiting together, and that shared experience tends to soften people towards one another. Charity, called zakat al-fitr, is specifically required at the end of Ramadan, ensuring that even those without means can celebrate the feast of Eid al-Fitr that follows.

If you are thinking about what fasting might mean in your own life, Islamic teaching offers something concrete to sit with. The tradition does not frame fasting as punishment or as a transaction, as though God needs you to be hungry. Rather, it understands the fast as a form of remembrance, a way of repeatedly returning your attention to what actually sustains you. Every moment of hunger or thirst in the day becomes a small prompt: you need more than food. There is also a compassion dimension that Islamic scholars have long emphasised. Fasting builds empathy with those who are hungry not by choice but by circumstance. It makes the discomfort of poverty briefly real to people who might otherwise only understand it in the abstract. Whether or not you are Muslim, that is a profound idea: that choosing to go without, even temporarily, can open you to others who have no such choice.
