What we are looking at
نْ
Noon Sakinah
A noon with no vowel
A ن carrying a sukoon (ـْ) — it has no fatha, kasra, or damma. It sits still, like in مَنْ or أَنْعَمْتَ.
ـٌ ـٍ ـً
Tanween
A doubled ending vowel
A doubled short vowel on a word's end that sounds like a noon but isn't written as one — كِتَابٌ, بَابٍ, عِلْمًا.
Here's the key: they follow the exact same four rules. An ending n sound is an ending n sound — so we treat them as one thing from now on.
