-part-5:  Al-IDGHAM(NOON SAKINAH) الإدغام

Al-IDGHAM الإدغام

 Al-IDGHAM mean :insertion-Insertion of one thing into another 

IDGHAM in Tajweed: The meeting of a non-voweled letter with a voweled letter so that the two letters become one emphasized letter of the second type.
The letters causing idghaam of noon saakinah and tanween are those contained in the word
َ ٌَرَ مَ لَُ و ن


This means if one of these six letters are at the beginning of theword that immediately follows a word ended in noon saakinah or a tanween, then the noon merges into the next letter.

Types of Idghaam

1- Idghaam with Ghunnah
2-Idghaam without Ghunnah

IDGHAM WITH GUNNAH : —->> م – ن – و – ى

When noon saakinah and tanween comes at the end of a word and one of these letters is first letter of the next word the rule is applied.
It is not pronounced clearly instead it is merged in the next letter with ghunnah (nasalization).


when one of these two letters begin the word that follows one that has noon saakinah or tanween at the end of it ,we then completely merge the noon into the next letter without ghunnah (complete insertion).

Note: the Noon Saakin or the Tanween and the Idgham letter have to be in
two different words, otherwise the reader is not Supposed to do Idghaam. In
this case it will be Izhaar Motlaq (أظهار مطلق)
and this case can be found only
in 4 words in Quran

    Assalamu Alaikum Warehmatullahi Wabarakatuhu

    In some arabic books I don’t see Idgham rule being applied on Maan Istafamiyah, why is that?

    For an example:

    من ربک؟
    Who is your lord?

    I never see tashdeed on Raa and Idgham is not being done. Why is that?

      Because these are tajweed rules not arabic rule , The arabic native speakers don’t do this in normal life

    Asalaamualykum I’ve really been stuck on this. There are yarmaloon letters that come after noon sakin tanwin and they will usually have the w shape tashdeed on it. What do I do when the w shape tashdeed is not showing on the letter. Even if it’s not the four word (dunya, qinwanun etc) and it’s separated will it still be ghunnah?
