Can I fast the 10th of Muharram without fasting the 9th?

Yes. A fast on the 10th alone is fully valid. However, the Prophet expressed his wish to fast the 9th as well in the following year (Sahih Muslim 1134a), so adding Tasua follows his Sunnah and distinguishes the fast from earlier traditions.

When is the cut-off time for making the Niyyah?

It is best to form the intention between Maghrib and Fajr the night before. If you have not eaten or drunk since Fajr, you may still make a valid intention up until Islamic Midday, just before Zuhr enters.

Do I need to say the intention out loud?

No. The Niyyah takes place in the heart. Uttering the Arabic words aloud is optional and only helps focus the soul.

Can I make one intention for both days at once?

No. You must make a separate intention inside your heart for each individual day before Fajr enters. A single broad intention for the two days is not the correct method.

How to Make the Intention to Fast Tasua (9th) & Ashura (10th Muharram)

⚡ Quick Answer: The Niyyah (Intention)

You do not need to say your intention out loud; it happens in the heart. However, if you prefer to utter it, recite this the night before each fast:

For the 9th (Tasua): “Nawaytu an asuma ghadan yawma Tasua sunnatan lillahi ta’ala.” (I intend to fast tomorrow, the day of Tasua, for Allah).
For the 10th (Ashura): “Nawaytu an asuma ghadan yawma Ashura sunnatan lillahi ta’ala.” (I intend to fast tomorrow, Ashura, for Allah).
Fiqh Rule: You must make a separate intention inside your heart for each individual day before Fajr enters.

Fasting the 10th of Muharram (Ashura) carries the profound promise of wiping away the minor sins of the past year. However, the Prophet Muhammad (ﷺ) strongly urged his followers to pair it by also fasting the 9th of Muharram (Tasua).

Because voluntary (Nafl) fasts carry specific Islamic rulings regarding *when* and *how* the Niyyah must be made, getting your intention right is the first step to an accepted fast.

The 9th and 10th of Muharram hold some of the highest spiritual rewards in the Islamic calendar.

Word-for-Word Intention Table (Tasua & Ashura)

While the silent resolve in your mind as you set your morning alarm constitutes a valid Niyyah, uttering the words helps focus the soul. Use this simple pronunciation guide:

Day	Arabic Text	Transliteration	English Meaning
9th Muharram (Tasua)	نَوَيْتُ أَنْ أَصُومَ غَدًا يَوْمَ تَاسُوعَاءَ سُنَّةً لِلَّهِ تَعَالَى	Nawaytu an asuma ghadan yawma Tasua sunnatan lillahi ta’ala.	“I intend to fast tomorrow, the day of Tasua, as a Sunnah for the sake of Allah.”
10th Muharram (Ashura)	نَوَيْتُ أَنْ أَصُومَ غَدًا يَوْمَ عَاشُورَاءَ سُنَّةً لِلَّهِ تَعَالَى	Nawaytu an asuma ghadan yawma Ashura sunnatan lillahi ta’ala.	“I intend to fast tomorrow, the day of Ashura, as a Sunnah for the sake of Allah.”

Crucial Fiqh Rules: When is the Cut-off Time for Niyyah?

Because the fast of Muharram is a *Sunnah Mu’akkadah* (emphasized voluntary fast), Islamic jurisprudence offers a layer of mercy regarding your intention timing:

The Nighttime Preference: It is superior to form your resolve between Maghrib (sunset) and Fajr (dawn) the night before.
The Daytime Grace Period: If you wake up, realize it is the 9th or 10th of Muharram, and have not eaten, drunk, or engaged in marital relations since Fajr, you can validly make the intention right up until **Islamic Midday** (roughly 10 to 15 minutes before the time of Zuhr enters).

Can I fast the 10th without fasting the 9th?

Yes. Your fast on the 10th alone is 100% valid. However, Ibn Abbas (RA) narrated that when the Messenger of Allah fasted on the day of Ashura, he said: “If I live until the next year, I will certainly fast the ninth day as well.” (Sahih Muslim 1134a). Therefore, adding the 9th distinguishes the Islamic fast from the historical traditions of the People of the Book.

📌 TL;DR Summary (Takeaway Column)

The Goal: Fast both the 9th and 10th of Muharram to practice the Prophet’s Sunnah and achieve the expiation of a year of minor sins.
The Core Requirement: Intention sits in the heart; saying the Arabic text aloud is optional.
The Trap to Avoid: Making one broad intention for “the two days.” You must explicitly intend *Tasua* on night one, and *Ashura* on night two.
Missed the morning alarm? As long as you haven’t swallowed food or water since dawn, you can make the Niyyah up until just before Zuhr.
