Fasting on Monday and Thursday: The Sunnah and How to Build the Habit

The Prophet Muhammad ﷺ fasted on Monday and Thursday, week after week, year after year. When asked why, his answer was not about discipline, not about health, not about virtue signaling to his companions.

It was about something much more specific: "These are days on which deeds are presented to Allah. I love that my deeds are presented while I am fasting." (Sunan al-Tirmidhi 747)

That single motivation — wanting your deeds to be seen by Allah while you are in a state of worship — is what makes Monday-Thursday fasting different from almost any other voluntary act.

What Happens on These Two Days

The hadith on this is specific and consistent. On Mondays and Thursdays, the deeds of the servants are presented to Allah. The Prophet loved that his deeds from the previous week reached the Divine presence while he was engaged in worship.

The companion Abu Hurairah رضي الله عنه reported: "The Prophet ﷺ used to fast Monday and Thursday. He was asked about it and said: 'The gates of paradise are opened on Monday and Thursday. Every servant who does not associate anything with Allah will be forgiven — except two who have enmity between them. It will be said: Delay these two until they reconcile.'" (Sahih Muslim 2565)

Two major things happen on these days:

1. The divine records of your weekly deeds are presented
2. The gates of paradise open and forgiveness is extended — except to those holding grudges

Both of these facts make fasting on these days an act of alignment: you are worshipping in a specific period when your worship is being noticed in a specific way.

Monday Has a Special Status

The Prophet ﷺ was asked about fasting on Monday specifically and said: "It is the day on which I was born, and the day on which I received revelation." (Sahih Muslim 1162)

He honored Monday through fasting as a personal expression of gratitude for the blessings of his birth and prophethood. For his followers, fasting on Monday is a way of participating in that gratitude — of saying, through action, that the day the Prophet ﷺ came into this world matters.

The Habit Behind the Consistency

The Prophet ﷺ was not occasionally fasting on Monday and Thursday when he felt like it. He was fasting every week. This was a fixed rhythm — as regular as salah, as embedded in the weekly structure as Jummah.

This consistency is itself part of the teaching. The Prophet ﷺ said: "The most beloved deeds to Allah are those that are most consistent, even if they are small." (Sahih Bukhari 6465)

A small consistent act is more beloved to Allah than a large sporadic one. Monday-Thursday fasting is designed to be exactly that — a sustainable, repeatable practice that accumulates value week after week.

Building the Habit — Practically

The most common failure with Monday-Thursday fasting is inconsistency. People do it during Ramadan's momentum, lose it afterward, try to restart after a gap, and feel guilty for the gap.

Here is how to build it into your life durably:

Start with one day. Do not try to fast both days immediately if that feels daunting. Start with Monday only — it has the stronger individual narration. Fast every Monday for a month before adding Thursday.

Set your intention the night before. The voluntary fast can be intended any time before noon, but intending the night before removes the morning decision-making when you are groggy and the nafs is negotiating. A simple nighttime intention: "I intend to fast tomorrow, Monday, for the sake of Allah."

Prepare your suhoor. Even a small meal — a few dates, some water — before Fajr makes the fast significantly easier. Do not skip suhoor for voluntary fasts; the Prophet ﷺ encouraged it even as a small meal.

Use the deeds-presented framework. When you feel the hunger during the day, remind yourself: right now, on this day, my deeds are being presented to Allah and I am in a state of fasting. That context transforms hunger from annoyance into something meaningful.

Protect the streak. Once you have three consecutive weeks of Monday fasting, the streak itself becomes a motivator. Breaking it feels significant. Building it feels good. Use a tracker.

What About the Rest of the Week?

Monday-Thursday fasting does not exist in isolation. It connects to a broader structure of voluntary worship:

• The six fasts of Shawwal (after Ramadan) complete the year
• The white days (13th, 14th, 15th of each Islamic month) are another established voluntary fast
• The day of Arafah fast (9th Dhul Hijjah) is one of the most rewarded

Monday-Thursday fasting is arguably the most sustainable of these because it is attached to a weekly rhythm rather than a specific calendar date. Once it becomes habitual, it requires almost no planning — it just happens every week.

Common Questions

What if I travel on Monday or Thursday? Voluntary fasts during travel are permitted but not required. The Prophet ﷺ sometimes broke his voluntary fasts when traveling. You can make up the intention another day, or simply resume the following week without guilt.

What if I cannot fast due to illness or a medical condition? People with chronic illness, pregnant or breastfeeding women, and those with conditions that make fasting medically unsafe are fully excused from voluntary fasts. Making du'a for the intention to fast when able is rewarded.

Does the Monday-Thursday fast have to be unbroken to count? Once you make the intention and begin fasting, the day has meaning even if you need to break it due to necessity. Voluntarily breaking it for no reason after beginning is disliked but not a sin, and does not require makeup.

Can I fast Monday and Thursday every week during Ramadan? In Ramadan you are already fasting every day, so Monday and Thursday are automatically included. The voluntary nature of these two days has its specific reward in non-Ramadan months.

The Long Game

Two fasts per week, every week. By the end of a year, that is roughly 96 fasts — nearly as many as Ramadan, but spread across the entire year.

The compounding effect of this habit on the heart is significant. Regular fasting builds taqwa — the God-consciousness that changes how you react to temptation, how you treat people, and how deeply you connect with Allah. It is a slow, quiet transformation that most people only notice in retrospect.

But the person who has been fasting Monday and Thursday for three years is not the same person they were when they started. The nafs has been disciplined in a way that consistent worship alone cannot fully replicate.

The Prophet ﷺ built this habit and maintained it. It is one of the most accessible gateways to the discipline he modeled.
