Master the 4 Golden Rules of Nun Sakinah
There are only 4 things that can happen to a Nun Sakinah. Just like traffic lights tell cars to stop, go, or slow down, these rules tell the letter "Nun" how to behave.
If you master these 4 rules, you have mastered nearly 30% of all Tajweed rules in the Quran.
👉 The Rule: Whenever you see a نْ or Tanween (double vowel), look at the very next letter. That letter decides the rule.
The 4 Golden Rules
Here is the breakdown of the four distinct paths. Memorize the letters for each group.
1 Izhar (Clarity)
Pronounce the "N" clearly. No merging, no hiding. This happens with the 6 Throat Letters.
Example: Man-Aamana
2 Idgham (Merging)
Skip the "N" and merge it into the next letter. The letters are YAR-MA-LOON.
Example: Mir-Rabbihim
3 Iqlab (Conversion)
Turn the "N" sound into a hidden "Meem" (M). This only happens with one letter.
Example: Mim-Ba'di
4 Ikhfa (Hiding)
Hide the "N" sound with a nasal buzz. This applies to all remaining 15 letters.
Example: An-Tum
