The Best Way to Fast on Ashura (10th Muharram): Authentic Sunnah Guide 2026

Ashura, the 10th day of Muharram, is one of the most virtuous and blessed days of the Islamic year. It is a day filled with divine mercy, gratitude, forgiveness, and countless spiritual lessons for every believer. Millions of Muslims around the world observe fasting on this day, eagerly reviving the Sunnah of our beloved Prophet Muhammad ﷺ.

But what is the best way to fast on Ashura? Should we fast for one, two, or three days? Are the common customs associated with this day authentic? In this comprehensive guide by Tazkiratul Quran Academy, we answer these questions based on the Holy Qur'an, authentic Hadiths, and the classical explanations of Islamic scholars.

What is Ashura?

The word Ashura (عاشوراء) is derived from the Arabic word "Asharah" (عشرة), which translates to "ten," explicitly referring to the 10th day of Muharram, the first month of the Islamic calendar.

This is a sacred day that Allah ﷻ honored long before the advent of Islam. When the Messenger of Allah ﷺ migrated to Madinah, he found the Jewish community fasting on this day. Curious about its significance, the Prophet ﷺ asked them why they fasted.

They replied that it was the monumental day on which Allah ﷻ saved Prophet Musa (عليه السلام) and the Children of Israel from the tyranny of Pharaoh by parting the sea. Upon hearing this, the Prophet ﷺ declared:

"نَحْنُ أَحَقُّ بِمُوسَى مِنْكُمْ"

"We have more right to Musa than you."

(Sahih al-Bukhari & Sahih Muslim)

Consequently, the Prophet ﷺ fasted on Ashura himself and commanded the Muslims to observe it as well.

The Virtue of Fasting on Ashura

One of the greatest blessings attached to this voluntary fast is the immense reward of forgiveness. It is a golden opportunity to wipe our spiritual slates clean.

The Messenger of Allah ﷺ said:

"أَحْتَسِبُ عَلَى اللَّهِ أَنْ يُكَفِّرَ السَّنَةَ الَّتِي قَبْلَهُ."

"I hope from Allah that fasting on the Day of Ashura will expiate the sins of the previous year."

(Sahih Muslim)

According to mainstream Islamic scholars, this refers specifically to the forgiveness of minor sins committed during the previous year. Major sins, however, require dedicated and sincere repentance (Tawbah).

The Best Way to Fast on Ashura

Islam beautifully encourages Muslims to distinguish their acts of worship from other religious traditions while preserving the original prophetic practices. To achieve this, scholars have categorized the levels of fasting on Ashura into three main options:

1. The Highest Level: Fast the 9th, 10th, and 11th of Muharram

Many classical scholars consider fasting three consecutive days to be the most complete and virtuous practice. This involves fasting on:

9th Muharram (Tasu'a)
10th Muharram (Ashura)
11th Muharram

This method combines various textual narrations and guarantees that Muslims clearly differ from the practice of the People of the Book. Among the narrations supporting this is:

"لَئِنْ بَقِيتُ لَآمُرَنَّ بِصِيَامِ يَوْمٍ قَبْلَهُ وَيَوْمٍ بَعْدَهُ."

"If I remain alive, I would command fasting a day before it and a day after it."

While scholars discuss the exact grading of this specific narration, fasting all three days remains highly recommended by many jurists to maximize reward and ensure accuracy regarding moon sightings.

2. The Core Sunnah Practice: Fast the 9th and 10th

The most widely recognized Sunnah practice is to fast the ninth day along with the tenth. The Prophet ﷺ explicitly intended to do this before his passing.

He ﷺ stated:

"لَئِنْ بَقِيتُ إِلَى قَابِلٍ لَأَصُومَنَّ التَّاسِعَ."

"If I live until next year, I will certainly fast the ninth."

(Sahih Muslim)

Although the Prophet ﷺ passed away before the following Muharram arrived, his documented intention established a permanent Sunnah for the Muslim Ummah. Therefore, pairing the 9th and 10th of Muharram is highly encouraged.

3. Can You Fast Only the 10th of Muharram?

Yes, absolutely. If someone cannot fast on the 9th or 11th due to professional commitments, travel constraints, illness, or personal circumstances, they should still strive to fast on the 10th rather than missing out on the reward entirely.

The scholars have a beautiful legal maxim regarding this:

"ما لا يدرك جله، لا يترك كله."

"If all of something cannot be attained, then do not abandon it entirely."

Even fasting solely on the day of Ashura is a valid, tremendous act of worship that can earn you Allah’s forgiveness.

Why Did the Prophet ﷺ Want to Fast the Ninth Day?

The profound wisdom behind pairing the tenth day with the ninth day includes:

To distinguish the Muslim community from the religious practices of the People of the Book.
To increase our overall volume of voluntary good deeds (Nawafil).
To safeguard against any human error or uncertainty regarding the local moon sighting for the start of Muharram.
To obediently fulfill the direct intention and spiritual guidance of the Prophet ﷺ.

Lessons We Learn from Ashura

Ashura is far more than a ritual of abstaining from food and drink; it is an annual spiritual university packed with powerful reminders for the soul.

Allah Always Helps the Believers

When Prophet Musa (عليه السلام) and his followers were cornered at the edge of the sea with Pharaoh’s ruthless army rapidly closing in from behind, human logic suggested there was no escape. Yet, Musa’s faith remained unshaken. Allah ﷻ commanded:

"فَاضْرِبْ بِعَصَاكَ الْبَحْرَ"

"Strike the sea with your staff."

The sea instantly split into clear dry paths, saving the believing servants and drowning the oppressors. Ashura reminds every struggling Muslim today that no matter how dark or impossible your situation seems, Allah's divine help is always near if you trust Him.

Gratitude is Expressed Through Worship

Prophet Musa (عليه السلام) did not celebrate his victory with worldly parties; he fasted out of sincere gratitude to his Creator. Our beloved Prophet Muhammad ﷺ did the exact same. This teaches us that true gratitude (Shukr) to Allah is best expressed through physical obedience, worship, humility, and constant remembrance.

Common Misconceptions About Ashura

Over the centuries, several cultural customs have crept into the observation of Ashura that lack authentic evidence from the Qur'an or Sunnah.

Applying Surma (Kohl) or Henna

The famous classical traditionist Ibn Rajab رحمه الله explicitly stated:

"وكل ما روي في فضل الاكتحال والاختضاب يوم عاشوراء فهو موضوع."

"Every narration regarding the special virtue of applying kohl (surma) or henna on the Day of Ashura is fabricated."

Therefore, believing that applying cosmetics on this specific day brings specialized rewards has no authentic basis in orthodox Islamic practice.

Spending Extra on the Family

Many people frequently circulate the following narration across social media:

"من وسع على أهله يوم عاشوراء أوسع الله عليه سائر سنته."

"Whoever spends generously on his family on the Day of Ashura, Allah will provide abundance for him throughout the rest of the year."

When the great Imam Ahmad ibn Hanbal رحمه الله was questioned about the authenticity of this statement, he bluntly replied:

"ليس بشيء."

"It is nothing (it has no authentic basis)."

This report was recorded by Al-'Uqayli in Ad-Du'afa and is categorized in Da'eef At-Targheeb wat-Tarheeb, meaning it is legally unsuitable as evidence for a custom. While being generous and loving to your family is highly rewarded every day in Islam, there is no authentic Sunnah that singles out the day of Ashura for shopping or extra financial spending.

How to Make the Most of Ashura

Aside from observing the fast, a Muslim should strive to utilize every hour of this sacred day to draw closer to Allah ﷻ. Consider implementing these practical spiritual tips:

Dedicate specific time blocks to recite the Holy Qur'an with deep reflection and contemplation.
Make sincere, private Tawbah (repentance) for past mistakes, resolving to change for the better.
Increase your daily tongue engagement in Dhikr (remembrance) and Istighfar (seeking forgiveness).
Send abundant Salawat (blessings) upon our beloved Prophet Muhammad ﷺ.
Give hidden charity (Sadaqah) within your means to support the less fortunate.
Make heartfelt, emotional Du'a for yourself, your family, your deceased loved ones, and the struggling global Ummah.
Actively step up to help those in need and proactively strengthen strained family ties.
