The izhar halqi letters are the six throat letters ء ه ع ح غ خ (hamza, ha, ‘ayn, ḥa, ghayn and kha). When one of them comes right after a noon sakinah or tanween, you pronounce the noon clearly, from the tip of the tongue, with no lengthened nasal sound and no hiding or merging. It sounds like the simplest rule in tajweed, yet it is where students most often add a ghunnah that should not be there. In our one-to-one Tajweed lessons, teachers usually fix izhar in the first few sessions because it sets the standard for every other noon rule.
This guide explains where the six letters come from, why the noon stays clear before them, one Quran example for each letter, and the small mistakes that are easy to miss in your own recitation. Everything follows the riwayah of Hafs ‘an ‘Asim.
Key takeaways
- Izhar halqi applies when noon sakinah or tanween meets ء ه ع ح غ خ, inside one word or across two words.
- The noon is clear because the throat is far from the tip of the tongue, so there is nothing to merge or hide.
- The ghunnah stays at its minimum: never hold it for two counts as in ikhfa or idgham.
- Izhar is strongest with ء ه and weakest with غ خ, where English speakers often slip into an “ng” sound.
Where the Six Letters Come From
“Halqi” means “of the throat” (al-halq). The six letters are produced in three areas of the throat, from deepest to nearest the mouth:
| Area of the throat | Letters | Level of izhar |
|---|---|---|
| Deepest part (aqsa al-halq) | ء ه | Strongest |
| Middle (wasat al-halq) | ع ح | Middle |
| Nearest the mouth (adna al-halq) | غ خ | Weakest |
Imam Sulayman al-Jamzuri lists them in exactly this order in Tuhfat al-Atfal, the classic beginner’s poem on noon and meem rules:
هَمْزٌ فَهَاءٌ ثُمَّ عَيْنٌ حَاءُ ، مُهْمَلَتَانِ ثُمَّ غَيْنٌ خَاءُ
“Muhmalatan” means “undotted”: it tells you the ‘ayn and ḥa in this line are the letters without dots, so you do not confuse them with ghayn and kha. Students also memorize a popular phrase whose words start with the six letters: أَخِي هَاكَ عِلْمًا حَازَهُ غَيْرُ خَاسِرِ.
If you want to practice where each letter is produced, our guide to pronouncing difficult Arabic letters covers the throat letters in detail.
Why the Noon Stays Clear
Every noon sakinah rule comes down to one question: how close is the next letter to the noon? The noon is made at the tip of the tongue against the gum ridge, with a nasal sound from the nose.
- When the next letter is very close or shares qualities with the noon (ي ر م ل و ن), the noon merges into it: idgham.
- When the next letter is at a middle distance (the 15 ikhfa letters), the noon is hidden: ikhfa.
- When the next letter is ب, the noon turns into a hidden meem: iqlab.
- When the next letter is in the throat, it is so far from the tongue tip that merging or hiding would be unnatural. So the noon is simply pronounced in full: izhar.
This also explains the three levels of izhar. Hamza and ha are the farthest from the noon, so izhar there is strongest. Ghayn and kha are nearest the mouth, so izhar there is weakest. In fact, in the reading of Abu Ja’far, one of the ten canonical readers, the noon is hidden before ghayn and kha (with a few exceptions). In Hafs, izhar applies to all six without exception.
What “Clear” Means in Practice
Izhar does not mean the noon has no nasal sound at all. Ghunnah is a permanent quality of noon and meem. In izhar, it is simply kept at its minimum natural level, the same as any ordinary noon, and is not held or stretched. Think of it as three actions:
- The tongue tip touches the gum ridge firmly and produces a complete “n”.
- The nasal sound is brief, no longer than the noon in a plain word.
- You move straight to the throat letter with no pause, no extra vowel and no bounce.
Do not overcorrect by cutting the noon so sharply that it sounds like a stop. The noon should be smooth and complete, then released directly into the next letter.
The Six Letters With Quran Examples
Izhar halqi can occur inside one word (noon sakinah only) or across two words (noon sakinah or tanween). Tanween always comes at the end of a word, so with tanween izhar is always across two words.
| Letter | Inside one word | Across two words | Tanween |
|---|---|---|---|
| ء | وَيَنْأَوْنَ (Al-An’am 6:26) | مَنْ آمَنَ (Al-Baqarah 2:62) | كُفُوًا أَحَدٌ (Al-Ikhlas 112:4) |
| ه | مِنْهُمْ (e.g. Al-Baqarah 2:75) | إِنْ هُوَ (An-Najm 53:4) | جُرُفٍ هَارٍ (At-Tawbah 9:109) |
| ع | أَنْعَمْتَ (Al-Fatiha 1:7) | مِنْ عِلْمٍ (Al-Kahf 18:5) | سَمِيعٌ عَلِيمٌ (e.g. Al-Baqarah 2:181) |
| ح | يَنْحِتُونَ (Al-Hijr 15:82) | مَنْ حَادَّ (Al-Mujadilah 58:22) | نَارٌ حَامِيَةٌ (Al-Qari’ah 101:11) |
| غ | فَسَيُنْغِضُونَ (Al-Isra 17:51) | مِّنْ غِلٍّ (Al-A’raf 7:43) | عَزِيزٌ غَفُورٌ (Fatir 35:28) |
| خ | وَالْمُنْخَنِقَةُ (Al-Ma’idah 5:3) | مِّنْ خَوْفٍ (Quraysh 106:4) | يَوْمَئِذٍ خَاشِعَةٌ (Al-Ghashiyah 88:2) |
Notice that noon sakinah before hamza inside one word is rare; وَيَنْأَوْنَ is the example teachers usually give. The other five letters appear inside words regularly.
Use the finder below to check any letter: tap the letter that follows the noon, and it shows the rule with an example. Try all six throat letters, then compare them with a few ikhfa letters to hear the difference in your head.

The Mistakes Teachers Correct Most
1. Adding a ghunnah
The most common error by far. Students who have just learned ikhfa start holding every noon, so أَنْعَمْتَ becomes “an~~~’amta”. Say it at a normal pace: the noon should take no longer than an ordinary “n”, then move straight on.
2. An “ng” sound before غ and خ
English speakers naturally say “ng” before a back-of-the-mouth sound, so مِنْ خَوْفٍ comes out as “ming-khawf”. That is the back of the tongue touching the palate instead of the tip touching the gum ridge. Keep the tongue tip firmly in place for the noon, then move to the kha.
3. A small pause or extra vowel
Some students separate the noon and the throat letter with a tiny gap or a half-vowel: “mini ‘ilm” instead of “min ‘ilm”. Izhar is clear but connected. There is no break between the two letters.
4. Moving the hamza’s vowel onto the noon
In مَنْ آمَنَ, some students read “manaamana”, sliding the hamza’s vowel back onto the noon. That transfer (naql) is a feature of other riwayat such as Warsh. In Hafs, the noon keeps its sukun and the hamza is pronounced clearly.
5. Weak throat letters
Izhar is only as good as the letter after it. If ح sounds like ه, or ع disappears, the clarity of the rule is lost. Work on your throat letters on their own first.
6. Treating hamzat al-wasl as a hamza
Izhar applies to a pronounced hamza (hamzat al-qat’). When a tanween meets a connecting hamza (hamzat al-wasl), the hamza is not pronounced, so the tanween’s noon is given a kasra to join the words, as in نُوحٌ ابْنَهُ (Hud 11:42), read “nuhuni-bnahu”.
Practice drill: read the examples in the table above in pairs with an ikhfa example, such as مِنْ عِلْمٍ then مِن قَبْلِ. Record yourself. In the izhar word, the noon should be short and crisp; in the ikhfa word, you should hear a held nasal sound for two counts.
Izhar Halqi vs Other Types of Izhar
The word izhar appears several times in tajweed, and students often mix them up:
- Izhar halqi: noon sakinah or tanween before the six throat letters (this article).
- Izhar shafawi: meem sakinah before any letter except ب and م, as in لَهُمْ فِيهَا. Our guide to meem sakinah rules explains it.
- Izhar mutlaq: noon sakinah before ي or و inside one word, as in الدُّنْيَا, where idgham would normally apply but does not.
- Izhar qamari: the lam of “al” pronounced clearly before the moon letters, as in الْعَالَمِينَ.
Interestingly, the six throat letters are all among the moon letters, so the lam of “al” is also pronounced clearly before them. Once izhar halqi is solid, the natural next step is ikhfa: see our guide to the 15 ikhfa letters and how the ghunnah changes with each.
How to Make Izhar Automatic
- Learn the letters with the poem line until you can say them in order without thinking.
- Spot them in the mushaf. In the Madinah mushaf, a noon in izhar carries a visible sukun, and tanween before a throat letter is written with its two marks stacked one over the other. In ikhfa and idgham, the noon has no sukun and the tanween marks are offset. Your eye can learn to spot the rule before you reach it.
- Read Surah Al-Fatiha and Juz Amma slowly, marking every izhar halqi with a pencil.
- Recite to a teacher. Extra ghunnah is hard to hear in your own voice, and a teacher in a Tajweed rules course will catch it in seconds. For the bigger picture of where this rule fits, read our overview of Quran tajweed rules.
Frequently Asked Questions
What are the 6 izhar halqi letters?
They are the throat letters ء ه ع ح غ خ: hamza, ha, ‘ayn, ḥa, ghayn and kha. When any of them follows a noon sakinah or tanween, the noon is pronounced clearly with no lengthened ghunnah.
Is there ghunnah in izhar halqi?
The noon keeps its natural, minimal nasal quality, because ghunnah is a permanent feature of the letter. But it is not held or extended. Holding it for two counts, as in ikhfa, is a mistake.
Why is it called izhar halqi?
Izhar means making clear, and halqi means “of the throat”. The rule is named after the throat letters that cause it, to distinguish it from izhar shafawi (meem sakinah) and izhar mutlaq.
Does izhar halqi happen inside one word?
Yes, with noon sakinah, as in أَنْعَمْتَ and يَنْحِتُونَ. With tanween it can only happen across two words, because tanween always comes at the end of a word.
How can I check that my izhar is correct?
Record yourself reading pairs of izhar and ikhfa examples and listen for the difference in noon length. The most reliable check is reciting to a qualified teacher in live Tajweed classes, who can hear a small extra ghunnah or “ng” sound immediately. You can start with a free trial class.
