The Art of Subtlety: Understanding The Ikhfa Letters in Tajweed
Ikhfa (الإخفاء) is a fundamental rule in the science of Tajweed, the art and discipline of correctly pronouncing the Ikhfa letters and words of the Quran. Ikhfa literally means “to conceal” or “to hide,” and in the context of Tajweed, it refers to the partial concealment or merging of the Noon Sakinah (نْ) or Tanween (ً ٍ ٌ) sound when it is followed by certain specific letters in the Arabic alphabet. This concealment is characterized by a nasal sound called ghunnah, maintained for approximately two counts.

The Rule of Ikhfa Haqiqi
The rule of Ikhfa Haqiqi (real concealment) applies when the silent nun (نْ) or one of the three forms of tanwin comes before one of the fifteen letters of Ikhfa. This rule is crucial for making the recitation of the Quran beautiful and melodious. The sound of the silent nun or tanwin not entirely merged into the following letter (like in Idgham), nor it clearly pronounced (like in Izhar). Instead, it’s disguised and pronounced with a light hum from the nose, known as ghunnah.
The sound of the silent nun or tanwin is pronounced from the nasal passage, while the rest of the sound comes from the mouth, preparing for the pronunciation of the next letter. The mouth and tongue take the position of the next letter, but the sound of the nun or tanwin is concealed with a light ghunnah.

The Ikhfa Letters (Fifteen)
The rule of Ikhfa applies when the noon saakinah (نْ) or tanween (ـً, ـٍ, ـٌ) is followed by one of the fifteen Ikhfa letters. These fifteen letters are the remaining Arabic letters after excluding the six letters of Idh-har (أ, هـ, ع, ح, غ, خ), the six letters of Idgham (ي, ر, م, ل, و, ن), and the one letter of Iqlab (ب).
For easy memorization, these fifteen letters compiled into a mnemonic verse in classical Tajweed texts. The first letter of each word in the following verse represents an Ikhfa letter:
صِفْ ذَا ثَنَا كَمْ جَادَ شَخْصٌ قَدْ سَمَا دُمْ طَيِّبًا زِدْ فِي تُقَى ضَعْ ظَالِمَا
The fifteen Ikhfa letters are:
- ص (Saad)
- ذ (Dhaal)
- ث (Thaa)
- ك (Kaaf)
- ج (Jeem)
- ش (Sheen)
- ق (Qaaf)
- س (Seen)
- د (Daal)
- ط (Taa)
- ز (Zaa-y)
- ف (Faa)
- ت (Taa)
- ض (Dhaad)
- ظ (Dhaa)
Understanding and correctly applying the rule for each of these fifteen letters is crucial for achieving proficiency in Tajweed. The key is to realize that the manner in which Ikhfa performed varies depending on the specific succeeding letter, which is the heart of its complexity.
How Ikhfa Is Pronounced
When a Noon Sakinah or Tanween followed by an Ikhfa letter:
- The Noon sound not fully articulated as in clear pronunciation (Izhar).
- Nor it fully merged with the subsequent letter as in Idgham.
- Instead, the Noon partially concealed, producing a nasalized sound (ghunnah) lasting for about two counts.
- The tongue does not touch the roof of the mouth as it does in Idgham.
- The quality of the nasal sound may be “thicker” or “lighter” (full mouth vs empty mouth) depending on the phonetic nature of the succeeding Ikhfa letter. Full mouth letters (like ص, ض, ط, ظ, ق) create a thicker pronunciation, while empty mouth letters (like ت, ث, ج, د, ذ, ز, س, ش, ف, ك) produce a lighter nasal sound.
The Practice of Ikhfa: Examples (The Ikhfa Letters)
To truly understand Ikhfa, it’s best to look at some practical examples from the Quran.
With Silent Nun (نْ):
- أَنْذَرْتَهُمْ (Andhartahum): The silent nun (نْ) followed by ذ (Dhal). The sound of the nun hidden with a ghunnah, and the mouth prepares for the pronunciation of “dhal.”
- مِنْ جُوعٍ (Min Jue): The silent nun followed by ج (Jeem). The nun’s sound concealed, and a ghunnah made.
- وَأَنْتُمْ (Wa’antum): Here, the silent nun followed by the letter ت (Ta). The sound of “nun” not fully pronounced; it concealed with a ghunnah as the tongue prepares to pronounce “ta.”
With Tanwin:
- رِيحًا صَرْصَرًا (Rihan sarsara): The tanwin (ًا) on “Rihan” followed by the letter ص (Sad). The sound of the tanwin concealed with a ghunnah.
- خَلْقٌ كَثِيرٌ (Khalqun kathir): The tanwin (ٌ) on “Khalqun” followed by the letter ك (Kaf). The sound of the “un” concealed, and a ghunnah produced.
- جَنَّاتٍ تَجْرِي (Jannatin tajri): The tanwin (ٍ) on “Jannatin” followed by the letter ت (Ta). The sound of the “in” hidden with a ghunnah.
- مَاءً زَكِيًّا (Ma’an zakiyya): The tanwin (ً) on “Ma’an” followed by the letter ز (Zay). The sound not fully pronounced but concealed with a hum.
The Coloring of the Ghunnah: Heavy vs. Light
The fifteen Ikhfa letters categorized based on their sound quality, which, in turn, dictates the quality of the accompanying ghunnah.
- Heavy Ghunnah (Mufakhamah – مُفَخَّمَة)
If the Ikhfa letter that follows the noon saakinah or tanween is a Heavy Letter (Huroof Al-Isti’laa’), the ghunnah itself becomes heavy and resonant (or mufakhamah). The heavy letters among the Ikhfa set are:
- ص (Saad)
- ض (Dhaad)
- ط (Taa)
- ظ (Dhaa)
- ق (Qaaf)
When reciting the noon before these letters, the back of the tongue should rise, giving the ghunnah a deep, full, and round sound, reflecting the quality of the heavy letter.
Example (Heavy): In the word مِنْ قَبْلُ (min qablu), the ‘n’ sound concealed, and the ghunnah takes on the heavy quality of the ق (Qaaf).
- Light Ghunnah (Muraqqaqah – مُرَقَّقَة)
If the Ikhfa letter is a Light Letter (Huroof Al-Istifal), the accompanying ghunnah pronounced as light and thin (or muraqqaqah). The light letters among the Ikhfa set are the remaining ten letters:
- ذ (Dhaal), ث (Thaa), ج (Jeem), ش (Sheen), س (Seen), د (Daal), ز (Zaa-y), ف (Faa), ت (Taa), ك (Kaaf)
When reciting the noon before these letters, the tongue remains low and flat, resulting in a bright, light, and less resonant ghunnah.
Example (Light): In the word إِنْ كُنْتُمْ (in kuntum), the ghunnah before the ك (Kaaf) is light, matching the nature of the ك.
Importance of Ikhfa and The Ikhfa Letters in Quranic Recitation
Mastering Ikhfa is critical for precise and melodious Quranic recitation. It ensures the reader respects the divine articulation rules passed down through generations, promoting clarity and beauty. The Prophet Muhammad (peace upon him) emphasized the merit of reciting the Quran correctly, and proficiency in Tajweed—including Ikhfa—brings the reciter closer to the noble status mentioned in the Hadiths.
Common Errors in Ikhfa:
- Over-touching: The most frequent mistake is allowing the tongue to fully touch the makhraj of the preceding noon (ن), which incorrectly turns the Ikhfa into a clear pronunciation (Idh-har) followed by a ghunnah.
- Insufficient Ghunnah: Failing to sustain the nasal sound for the required two counts, leading to a clipped or incomplete Ikhfa.
- Incorrect Coloring: Not differentiating between the heavy and light ghunnahs. Forgetting to raise the back of the tongue for the heavy letters (ص, ض, ط, ظ, ق) results in a light ghunnah, which changes the intended meaning of the recitation.
