In this guide We are gonna learn The Four Rules of Noon Saakinah and Tanween
One of the most important topics in Tajweed is understanding the rules of Noon Saakinah (نْ) and Tanween (ً ٍ ٌ). These rules control how the “N” sound is pronounced when it appears without a vowel or at the end of a word.
Applying these rules correctly makes recitation smooth, clear, and beautiful. There are four main rules, and each depends on the letter that comes after Noon Saakinah or Tanween.
1️⃣ Idhhar (Clear Pronunciation)
Meaning: To pronounce clearly.
Idhhar occurs when Noon Saakinah or Tanween is followed by one of the throat letters:
ء – ه – ع – ح – غ – خ
In this case, the “N” sound is pronounced clearly without merging or nasal hiding.
Example:
مِنْ هَادٍ
The Noon is pronounced clearly before ه.
2️⃣ Idgham (Merging)
Meaning: To merge.
Idgham happens when Noon Saakinah or Tanween is followed by one of these letters:
ي – ر – م – ل – و – ن
These letters are grouped in the word: يرملون
There are two types:
🔹 Idgham with Ghunnah (nasal sound)
Letters: ي – ن – م – و
The Noon merges into the next letter with a nasal sound.
Example:
مِنْ وَالٍ
🔹 Idgham without Ghunnah
Letters: ر – ل
The Noon merges completely without nasal sound.
Example:
مِنْ رَبِّهِم
3️⃣ Iqlab (Conversion)
Meaning: To change.
Iqlab occurs when Noon Saakinah or Tanween is followed by the letter:
ب
The Noon sound changes into a hidden Meem (م) sound with Ghunnah.
Example:
مِنْ بَعْدِ
It is pronounced like: “Mim ba‘di” (with nasal sound).
4️⃣ Ikhfa (Hidden Sound)
Meaning: To hide.
Ikhfa occurs when Noon Saakinah or Tanween is followed by any of the remaining 15 letters.
In this case, the Noon sound is partially hidden with a soft nasal sound (Ghunnah), without fully merging.
Example:
مِنْ شَرِّ
The Noon is neither fully clear nor fully merged — it is hidden.
Why These Rules Are Important
- They create smooth transitions between words
- They preserve proper pronunciation
- They enhance the rhythm of recitation
- They prevent pronunciation errors
Without applying these rules, recitation may sound unnatural or incorrect.
Tips for Practice
- Memorize the letter groups for each rule
- Practice slowly with short surahs
- Focus on identifying the letter after Noon Saakinah
- Listen to experienced reciters
