Letters of Ikhfaa & Reciting the Holy Quran with perfect Tajweed is a deeply rewarding spiritual journey.
Among the most foundational concepts a student encounters when learning how to read the Quran are the rules of Noon Sakinah (a Noon with no vowel) and Tanween (the hidden Noon sound at the end of words, represented by double vowels like “an,” “in,” or “un”).
These rules are divided into four main categories: Izhar (Clarity), Idgham (Merging), Iqlab (Changing), and Ikhfa (Concealing).
For many beginners, mastering the ikhfa rules can be slightly challenging because it requires a specific nasal sound and mouth positioning. In this comprehensive guide by Arkan Academy, we will explain exactly what is ikhfa in tajweed, list the ikhfa letters, and provide clear ikhfa examples so you can beautify your recitation today.
What is Ikhfa? Understanding the Ikhfa Meaning
Before diving into the technical application, we must first understand the ikhfa meaning.
- Linguistic Meaning: In the Arabic language, the word ikhfa (إخفاء) literally translates to “hiding” or “concealing.”
- Tajweed Meaning: So, what is ikhfa in tajweed? Applied to recitation, it is the pronunciation of a non-voweled letter (Noon Sakinah or Tanween) in a state between clear pronunciation (Izhar) and complete merging (Idgham).
When you apply ikhfa, the tongue does not touch the roof of the mouth to make a sharp “N” sound. Instead, you hide the “N” sound, keep your mouth hovering near the articulation point of the letter that comes immediately after it, and produce a nasal sound (Ghunnah) from your nasal cavity for two beats.

The 15 Ikhfa Letters (Letters of Ikhfaa)
To know when to apply this rule, you must memorize the triggers. If a Noon Sakinah or Tanween is followed by any of the letters of ikhfaa, the rule must be applied.
There are 28 letters in the Arabic alphabet. Once you remove the letters for Izhar (6), Idgham (6), and Iqlab (1), you are left with exactly 15 ikhfa letters.
Here are the 15 ikhfaa letters you need to memorize:
- ت (Ta)
- ث (Tha)
- ج (Jeem)
- د (Dal)
- ذ (Dhal)
- ز (Zay)
- س (Seen)
- ش (Sheen)
- ص (Sad)
- ض (Dhad)
- ط (Ta)
- ظ (Zha)
- ف (Fa)
- ق (Qaf)
- ك (Kaf)
A Quick Memorization Tip: Classical Tajweed scholars, like Imam Al-Jamzuri in his famous poem Tuhfat al-Atfal, gathered the ikhfa letters at the beginning of the words in this poetic verse to make them easier to remember: (صِفْ ذَا ثَنَا كَمْ جَادَ شَخْصٌ قَدْ سَمَا … دُمْ طَيِّبًا زِدْ فِي تُقًى ضَعْ ظَالِمَا) The first letter of every word in this Arabic couplet represents one of the letters of ikhfaa.
How to Apply the Ikhfa Rules Correctly
Knowing what is ikhfa is only half the battle; applying it correctly requires practice. The core ikhfa rules dictate that the nasal sound (Ghunnah) must be held for two beats (timing). However, there is a crucial detail that many students miss: The Ghunnah can be heavy or light.
The thickness of your ikhfa sound depends entirely on the letter that follows the Noon Sakinah or Tanween.
1. Heavy Ikhfa (Thick Ghunnah)
If the Noon Sakinah or Tanween is followed by one of the heavy (elevated) ikhfa letters—which are ص , ض , ط , ظ , ق (Sad, Dhad, Ta, Zha, Qaf)—the Ghunnah must also be pronounced with a heavy, full-mouth sound.
- How to do it: Elevate the back of your tongue while making the nasal sound, preparing for the heavy letter.
2. Light Ikhfa (Thin Ghunnah)
If the Noon Sakinah or Tanween is followed by any of the remaining 10 light ikhfaa letters (like ت, د, س, etc.), the Ghunnah must be pronounced lightly.
- How to do it: Keep your tongue flat and relaxed while making the nasal sound, preparing for the light letter.
Practical Ikhfa Examples from the Quran
To truly grasp the concept, let’s look at some clear ikhfa examples. Notice how the rule can occur within a single word or between two separate words.
Examples with Noon Sakinah (نْ):
- Light Ikhfa (One Word): أَنْتُمْ (An-tum) – The Noon is followed by ت (Ta). You hide the Noon and hold a light Ghunnah for two beats.
- Heavy Ikhfa (Two Words): مِنْ قَبْلُ (Min Qablu) – The Noon is followed by ق (Qaf). You hide the Noon and hold a heavy, thick Ghunnah for two beats.
- Light Ikhfa (One Word): الْإِنْسَانَ (Al-Insaana) – The Noon is followed by س (Seen).
Examples with Tanween (ً ٍ ٌ):
- Light Ikhfa: مَاءً ثَجَّاجًا (Maa’an thajjaajaa) – The Fatha Tanween is followed by ث (Tha).
- Heavy Ikhfa: قَوْمًا صَالِحِينَ (Qawman saaliheen) – The Fatha Tanween is followed by ص (Sad).
Note: In the Quranic script (Mushaf), a visual clue for ikhfa is that the Noon Sakinah will usually NOT have a Sukoon (the small circle/moon shape) drawn above it, and the Tanween strokes will be slightly staggered rather than perfectly aligned.
Perfect Your Tajweed with Arkan Academy
Reading about ikhfa rules and ikhfa examples is an excellent first step, but Tajweed is an oral science. It was passed down from the Prophet Muhammad (PBUH) through sound and hearing. You cannot truly know if your Ghunnah is the correct length, or if your tongue is in the right hidden position, without a qualified teacher listening to you.
At Arkan Academy, our certified, native Arab instructors specialize in taking you from theoretical knowledge to practical mastery. We listen to your recitation carefully, gently correct your pronunciation of the ikhfaa letters, and ensure you are reciting the Book of Allah exactly as it was revealed.
Frequently Asked Questions (FAQs) About Ikhfa in Tajweed
Q1: What is ikhfa in tajweed in simple words? To quickly grasp what is ikhfa in tajweed, you simply need to look at the linguistic ikhfa meaning, which translates to “hiding” or “concealing.” In practice, ikhfa occurs when you hide the sharp “N” sound of a Noon Sakinah or Tanween because it is immediately followed by one of the 15 specific ikhfa letters. Instead of a clear “N”, you produce a nasal humming sound (Ghunnah) for two counts.
Q2: How can I memorize the letters of ikhfaa easily? There are exactly 15 letters of ikhfaa. The most traditional way to memorize the ikhfaa letters is through the famous Tajweed poem, Tuhfat al-Atfal, which groups them at the beginning of its words. An easier modern trick to remember the ikhfa letters is the process of elimination: simply memorize the 6 letters of Izhar, the 6 of Idgham, and the 1 of Iqlab. Any remaining letter in the Arabic alphabet automatically falls under the ikhfa rules.
Q3: Are all ikhfa examples pronounced exactly the same way? No, they are not. A fundamental part of the ikhfa rules is understanding that the nasal sound (Ghunnah) acts like a chameleon; it adapts to the letter coming next. If you look at heavy ikhfa examples (where the Noon is followed by heavy letters like ص or ض), the sound must be thick and elevated. Conversely, light ikhfa examples (followed by letters like ت or س) require a flat, thin nasal sound.
Q4: Can I learn and practice these ikhfa rules online? Absolutely. Knowing what is ikhfa theoretically is different from pronouncing it correctly. Since Tajweed is an oral science, the best way to master the letters of ikhfaa is by reciting them live to a certified teacher. At Arkan Academy, our native Arab tutors provide 1-on-1 online sessions to correct your tongue placement and ensure your Ghunnah timing is perfectly accurate.
