This guide explains noon sakinah rules in simple American English, with letter groups, examples, and a fast checklist you can use right away.
Noon Sakinah Rules
How many rules of noon sakinah and tanween are there?
There are 4 rules: Izhar, Idgham, Iqlab, and Ikhfa.
The only step you really need:
Look at the next letter after Noon Sakinah (نْ) or Tanween (ً ٍ ٌ). That next letter decides the rule.
Quick chart (easy to memorize):
- Izhar = 6 letters (throat): ء ه ع ح غ خ
- Idgham = 6 letters: يرملون (with/without ghunnah)
- Iqlab = 1 letter: ب
- Ikhfa = 15 letters (the remaining set)
One helpful competitor note: 6 + 6 + 1 + 15 = 28 Arabic letters, which makes the system feel less overwhelming.

What Is Noon Sakinah? What Is Tannwin (Tanween)?
Noon Sakinah is the letter ن with a sukoon (نْ). It means the Noon has no vowel on it.
What is Tannwin (Tanween)?
Tanween appears as double vowel marks at the end of a noun, and it is pronounced like Noon Sakinah (“n” sound). In Arabic grammar, it also indicates indefiniteness (like “a/an” in English).
That’s why teachers group them together as noon sakinah and tanween rules—because the sound being governed is basically the same.
Parent note: some people type confusing searches like “Sakin and Tanween rules at noon.” Here, “Noon” means the Arabic letter ن, not the time of day.
Rule 1 — Izhar (Clear)
Izhar means you pronounce the “n” sound clearly with no merging. It happens when the next letter is one of the 6 throat letters: ء ه ع ح غ خ.
A nice “why” (helps adults and teens): one Tajweed manual explains that these letters come from the throat, and the Noon comes from the tongue—so merging them is difficult, which is why the recitation stays clear.
Example (simple):
- مَنْ آمَنَ → the Noon is read clearly (Izhar).

Rule 2 — Idgham (Merge)
Idgham means the Noon sound merges into the next letter when the next letter is from يرملون.
Idgham has two types:
- Idgham with ghunnah (nasal sound): ي ن م و
- Idgham without ghunnah: ل ر
Example:
- مَن يَقُولُ → Idgham (merging) is applied.
Quick timing note (parent-friendly):
Many beginner lessons teach ghunnah as “about two counts” as a learning tool.
At the same time, some Tajweed teachers caution that ghunnah timing is best learned by listening to a qualified teacher, not by rigid counting.
Rule 3 — Iqlab (Change to Meem Sound)
Iqlab is the easiest rule to spot: it happens only when the next letter is ب.
In Iqlab, the Noon/Tanween sound changes to a meem-like nasal sound (many mushafs even show a small meem as a hint).
Example:
- مِن بَعْدُ → Iqlab is applied (n → meem-like nasal sound).
Rule 4 — Ikhfa (Hide With Nasal Sound)
Ikhfa means you “hide” the Noon sound—so it’s not fully clear like Izhar and not fully merged like Idgham. It sits in between, with a nasal sound remaining.
Ikhfa happens with the 15 remaining letters, listed in many lessons as: ت ث ج د ذ ز س ش ص ض ط ظ ف ق ك

A simple 5-minute daily practice plan (kids + adults)
Do this daily for one week:
- Pick 10 ayahs from Juz ‘Amma.
- Circle every نْ and ً ٍ ٌ you see.
- Say out loud: “Next letter is ___, so the rule is ___.”
- Recite slowly, then repeat once at normal pace.
This matches what strong Tajweed educators emphasize: don’t rely on memorization alone—build it through listening and application.
Why Arabic (and Noon Sakinah rules) matter for Qur’an reading
Arabic is a sound-precise language. Small pronunciation changes can create major mistakes, and scholars explain that Muslims should learn to recite free from major errors.
And the Qur’an itself commands measured recitation (tartil), which scholars explain as distinct, careful recitation.
