After learning the correct articulation points of the letters, the next essential lesson in Tajweed is understanding how Noon Sakinah (a silent noon, نْ) and Tanween (the double vowel marks ـً ـٍ ـٌ) are pronounced when followed by different letters. These rules directly affect how smoothly and correctly the Quran is recited, and they are among the first Tajweed topics every student learns at Rattil Wa'artaqi.

What Are Noon Sakinah and Tanween?

Noon Sakinah is a noon letter (ن) with no vowel (sukoon) on it, such as in the word "مِنْ". Tanween is the doubled vowel sound that appears at the end of certain words, such as "كِتَابًا", "كِتَابٍ", or "كِتَابٌ". Both are treated the same way in Tajweed because they produce a similar sound, and the rule applied depends on the letter that comes right after them.

The Four Rules

1. Izhar (Clear Pronunciation)
When Noon Sakinah or Tanween is followed by one of the six throat letters (ء, هـ, ع, ح, غ, خ), it is pronounced clearly and fully, without any change or nasal sound.

2. Idgham (Merging)
When followed by one of the letters in the word "يرملون" (ي, ر, م, ل, و, ن), the noon sound merges into the following letter. There are two types: Idgham with ghunnah (nasal sound), used with ي, ن, م, و, and Idgham without ghunnah, used with ل and ر.

3. Iqlab (Conversion)
When followed by the letter ب, the noon sound is converted into a meem sound (م) with a light nasal tone, and a small meem symbol is often written above the letter in the Mushaf to indicate this rule.

4. Ikhfa (Concealment)
For the remaining fifteen letters, the noon sound is partially hidden, pronounced with a light nasal tone that is neither fully clear (as in Izhar) nor fully merged (as in Idgham). This is the most common rule and requires practice to master the right balance.

Why These Rules Matter

Applying these rules correctly is not just about following tradition. It reflects how the Quran was recited by the Prophet Muhammad, peace be upon him, and preserved through generations of qualified reciters. Skipping or misapplying these rules can make recitation sound unnatural or, in some cases, alter the intended flow of the verse.

Learning Noon Sakinah and Tanween rules takes practice and correction from a qualified teacher. At Rattil Wa'artaqi, our teachers guide students step by step through each rule with live examples and repetition until it becomes natural.
