Ikhfa Letters in Tajweed: The Complete Guide to Hidden Noon Sakinah

If you are learning to recite the Quran with Tajweed in the USA, UK or Europe, one of the first rules you will meet after learning the Arabic letters is ikhfa. Many students recognise Izhar and Idgham quickly, then get stuck on Ikhfa because the sound is subtle. This guide explains what Ikhfa is, lists all ikhfa letters, shows how to pronounce the rule correctly, and gives practice tips you can use at home or with an online teacher.

What Does Ikhfa Mean in Tajweed?

Ikhfa (إخفاء) in Arabic means “to hide” or “to conceal.” In Tajweed, it is the rule applied when a Noon Sakinah (نْ) or a Tanween (ً ٍ ٌ) is followed by one of fifteen specific letters. Instead of saying a clear “n” sound (as in Izhar) or fully merging into the next letter (as in Idgham), you hide the Noon and produce a light nasal sound (gunnah) while moving toward the next letter.

Think of three levels of Noon Sakinah treatment:

• Izhar – the Noon is fully clear (throat letters).
• Idgham – the Noon merges into the next letter.
• Ikhfa – the Noon is partially hidden with gunnah (the fifteen ikhfa letters).

There is also Iqlab, where Noon changes into a Meem sound before the letter ب. Together, these four rules cover every case of Noon Sakinah and Tanween in the Quran.

How Many Ikhfa Letters Are There?

There are 15 ikhfa letters. A common memory aid used in Tajweed classes is the line of poetry that gathers them, but you can also simply memorise the list below. These are the letters that trigger Ikhfa when they come right after Noon Sakinah or Tanween:

ت ث ج د ذ ز س ش ص ض ط ظ ف ق ك

Transliteration order: ta, tha, jeem, dal, dhal, zay, seen, sheen, sad, dad, ta (heavy), za (heavy), fa, qaf, kaf.

If the letter after Noon Sakinah or Tanween is any of these fifteen, apply Ikhfa. If it is a throat letter, apply Izhar. If it is one of the Idgham letters (ي ر م ل و ن), apply Idgham. If it is ب, apply Iqlab.

How to Pronounce Ikhfa Correctly

Correct Ikhfa has three parts. Practise them slowly before speeding up to your normal reading pace.

1. Prepare the mouth for the next letter

Do not park your tongue in the full Noon position. Instead, shape your mouth toward the articulation point (makhraj) of the letter that follows. For example, before ت or د the tongue tip is near the upper gum; before ك the tongue is farther back; before ف the lips and teeth are involved.

2. Hold a light nasal gunnah

Allow air to pass through the nose for roughly two counts (the length of a short gunnah). The Noon is “hidden,” so you should not hear a sharp, clear “nnn” as in Izhar, and you should not fully merge as in Idgham with gunnah.

3. Release into the next letter smoothly

Move from the nasal sound into the ikhfa letter without a pause or a hard stop. The connection should feel soft. If you hear a clear Noon, you are doing Izhar by mistake. If the Noon disappears completely into the next letter, you may be sliding into Idgham.

Ikhfa vs Izhar vs Idgham vs Iqlab

Students in the USA, UK and Europe often mix these four rules because English has no exact match for gunnah. Use this quick comparison:

Examples of Ikhfa from the Quran

Practice with short, well-known phrases. Read each one slowly, then check that you are hiding the Noon and keeping a soft nasal sound.

• مِنْ تَحْتِهَا (min tahtiha) – Noon before ت → Ikhfa.
• مِنْ شَرِّ (min sharri) – Noon before ش → Ikhfa.
• عَنْ صَلَاتِهِمْ (an salatihim) – Noon before ص → Ikhfa.
• كِتَابٌ كَرِيمٌ (kitabun kareem) – Tanween before ك → Ikhfa.
• قَوْمٍ تَسْفِكُونَ – Tanween before ت → Ikhfa.

Open any mushaf to Juz Amma and look for Noon Sakinah followed by ت، ث، ج، د، ذ، ز، س، ش، ص، ض، ط، ظ، ف، ق، ك. Mark them with a pencil until your eye recognises the pattern automatically.

Ikhfa Haqiqi and Ikhfa Shafawi

Teachers sometimes mention two names:

• Ikhfa Haqiqi – the main rule covered in this article: Noon Sakinah or Tanween before one of the fifteen letters.
• Ikhfa Shafawi – a related lip rule used when a Meem Sakinah is followed by ب. The Meem is lightly hidden with gunnah. It is not the same as the fifteen-letter Noon rule, but the “hiding” idea is similar.

When someone says “ikhfa letters” in a beginner class, they almost always mean the fifteen letters of Ikhfa Haqiqi.

Common Mistakes English-Speaking Students Make

1. Making a clear Noon – turning Ikhfa into Izhar. Fix: reduce tongue contact for Noon and keep the sound nasal.
2. Skipping gunnah – rushing into the next letter. Fix: count two beats of nasal sound before releasing.
3. Using the same mouth shape for every letter – Ikhfa before ك should not look or feel like Ikhfa before ت. Fix: prepare the makhraj of the following letter.
4. Confusing heavy and light letters – when the next letter is ص، ض، ط، ظ or ق, the hidden Noon takes on a slightly heavier colour. When the next letter is light (ت، ث، د…), keep the sound light. See also our page on heavy letters in Arabic.
5. Mixing Idgham letters into the ikhfa list – ي ر م ل و ن are not ikhfa letters. Review the list until it is automatic.

A Simple Practice Plan for Busy Families

You do not need long sessions. Ten focused minutes a day works well for adults and children in Western time zones.

1. Day 1–2: Memorise the 15 letters. Recite them aloud morning and evening.
2. Day 3–4: Read five short examples slowly, recording yourself on your phone.
3. Day 5–6: Read half a page of Juz Amma and underline every Ikhfa.
4. Day 7: Recite the same page to a teacher or a parent who knows the rule, and note corrections.

Children often learn the list faster with a chart on the wall and short games (“Is this letter Ikhfa or Izhar?”). Adults usually improve faster when a teacher listens live and corrects the gunnah length. For structured lessons, see our Learn Tajweed course page and online Quran courses for kids.

Why Ikhfa Matters for Beautiful Recitation

Ikhfa appears very often in the Quran. If it is unclear, the recitation sounds either too sharp (extra Noon) or too flat (missing nasal). Getting this one rule right improves the flow of almost every page you read. It also prepares you for longer rules such as Madd and for memorisation (Hifz), where clean pronunciation makes revision easier. Families who want both Tajweed and memorisation can look at online Quran memorization classes.

Learning Ikhfa with a Live Teacher on Zoom

Self-study charts help you recognise the letters, but a teacher hears whether your gunnah is too short, too long, or missing. Smart Quran Academy runs live classes on Zoom around the clock, with male and female teachers, so households in the USA, UK and Europe can choose a comfortable slot. Sisters who prefer a female teacher can start from our online Quran classes for ladies page. You can also begin from the homepage or the UK classes page if that is closer to your search.

New students receive 3 free trial classes. No card is needed to start. Regular plans are based on 20 classes per month, 30 minutes each, at $45 / $40 / $35 depending on the plan, with no registration fee.

Frequently Asked Questions

What are the ikhfa letters?

The fifteen letters: ت ث ج د ذ ز س ش ص ض ط ظ ف ق ك. When any of these follows Noon Sakinah or Tanween, you apply Ikhfa with gunnah.

Is Ikhfa the same as Idgham?

No. Idgham merges the Noon into the next letter. Ikhfa hides the Noon with a nasal sound but does not fully merge it.

Does Tanween follow the same ikhfa rule?

Yes. Tanween is treated like Noon Sakinah for Izhar, Idgham, Ikhfa and Iqlab.

How long should the gunnah of Ikhfa be?

About two counts — long enough to hear a soft nasal sound, short enough that the recitation still flows.

What is the difference between Ikhfa Haqiqi and Ikhfa Shafawi?

Ikhfa Haqiqi is for Noon/Tanween with the fifteen letters. Ikhfa Shafawi is for Meem Sakinah before ب.

Can children learn ikhfa letters easily?

Yes. A clear chart, short daily drills, and a patient teacher make the rule manageable for kids who already know the Arabic alphabet.

Which Tajweed rule should I learn before Ikhfa?

Learn the Arabic letters and the idea of Noon Sakinah first, then Izhar (throat letters), then Ikhfa. Many teachers teach the four Noon rules as one unit.
