The Meaning of Tajweed

Tajweed in the language is: “improving”, “precision”, and “perfection”, it is said… You make something good if you improve it and master it, and it’s the opposite of (badness).

Technically, tajweed means pronouncing each letter of the Qur’an from its articulation point (مخارج in Arabic) without changing. It means pronouncing letters correctly according to the rules of Tajweed, laid down by the Islamic scholars. And it is said: Tajweed means giving each letter its right and its due of the exits and attributes.

What Is Idgham in Tajweed?

Ingham in the Arabic language means to merge something into another. And in terminology, it means merging a constant letter into a vowel letter so that the two letters become one stressed letter- equals two.

Idgham in tajweed is applied in noon Sakin or Tanween, when they are preceded by any of those six letters ( ي، ر، م، ل، و، ن).

The Difference Between Noon Sakin and Tanween

1- The Noon sakin (static Noon) is an original letter of the word like منْ, and the tanween is an additional nun مlike غفورًا

2- The Noon sakin is fixed in the pronunciation and the writing, and the tanween is fixed in the pronunciation but not in writing ( as it can be tanween with Dumma غفورٌٌ, tanween with kasra غفورِِ, and tanween with fatha like غفورًا.

3- The noon sakin can be found is in the names, verbs, and letters, like من، ينمو، منتهى. But tanween can only be found in nouns, not in verbs or letters, except (لَيَكُونًا) in Surat Yusuf and (لَنَسْفَعًا) in Surat Al-Alaq. in the two cases, this tanween isn’t original but light noon used to emphasis the verb and called in Arabic نون التوكيد الخفيفة.

4- The consonant can be located in the middle of the word or at the end, but tanween is only located at the end.

Nun Sakinah Tanween
Original or Additional Always an Additional Nun
In nouns, verbs, or participles Only in nouns
In the middle or end of a word Only in the middle of a word
Pronounced & Written Pronounced as Nun but Not Written as Nun
Pronounced as Nun on stopping or joining Pronounced as Nun Only when joining

Idghaam Mutamaathilain is devidied into types

Al-Idghaam Al-kabeer:

occurs when a voweled letter precedes another voweled letter such that they become one letter with a shaddah on it.

قَالُواْ يَا أَبَانَا مَا لَكَ لاَ تَأْمَـنَّـا عَلَى يُوسُفَ وَإِنَّا لَهُ لَنَاصِحُونَ

The original word is تأمننا but the two letters are merged into تأمنّا

قَالَ أَتُحَاجُّونِّـي فِي اللّهِ وَقَدْ هَدَانِ

The original word is تحاجونني, but the two letters are merged into تحاجونى

Al-Idghaam Al Saghir

The meeting of a consonant letter with another vowel so that they become one stressed letter of the second gender. Like in this verse

فَمَا رَبِحَت تِّـجَارَتُهُمْ وَمَا كَانُواْ مُهْتَدِينَ

Idghaam Mutamaathilain

when two letters similar in their shape, pronunciation, and traits, for example, meet together. One of them is consonant, and the other is a vowel.

  • So the first letter is blended into the second; hence the second letter takes a shaddah ()
  • This applies whether it is in one or two words (whether both letters fall into the same word, or one letter falls at the end of the first word, and the second letter falls into the start of the second word)

See this example

“فَلا يُسرِفْ فِي القَتلِ”

In this sentence, the letter ف in يسرف is similar to the letter ف in فى, so both letters are merged into one letter.

 مَا سَلَكَكُمْ فِي سَقَرَ

اضرب بِّعصاك

يَلْهَث ذًّلِك

for both ث and ذ are emitted from the tip of the tongue.

{يا بُنَيَّ ارْكب مَّعنا}

Both أ and ى, which are called madd letters, are emitted from the tip of the tongue.

قَالَت طَّائِفَةٌ

قَد تَّعْلَمُوَن

ت , ط and د are pronounced from the same articulation point

Idghaam Mutaqaaribain (near, close)

This Idghaam occurs when two letters have different articulation points. However, they are close together (whereas the previous shared the same makhaarij.

قُل رَّبِ

بَل رَّفَعَهُ

Ingham Types ( Noon sakin )

There are two types of Idgham : With Gunna, and without Gunna.

Merging – Idgham- with Gunna

When noon sakin or tanween is followed by any of those four letters: ي، ن، م، و., Noon Sakin or tanween isn’t recited, but the reciter stresses the letter after ( pronounces it as if there is shadda on it)


  • (ن + ى ):

{إِنْ يَرَوْا} ، {فِئَةٌ يَنصُرُونَهُ}

and they are read like:

 فِئَتيَنْصرونه and إيَروا

(ن + و):

{مِنْ وَالٍ}، {إِيمَانًا وَهُمْ}

and they are read like: “

مِوَّال “،” إيمانَوَّهم”

(ن + م):

{مِنْ مَاءٍ}، {صِرَاطًا مُسْتَقِيمًا},

and they are read like

 مِمَّاء ” ، ” صراطمّسْقيماً “.

( ن + ن):

  {إِنْ نَحْنُ}، {مَلِكًا نُقَاتِلْ},

and they are read like

 إنَّحن”، “مَلِكنُّقاتل”.

  • Note: Ingham occurs when in two separate words, and it doesn’t occur if noon sakin is followed by any of those previously mentioned letters in one word, and that doesn’t occur in the Quran except in four words: {دُنْيا}، {قنْوان} ، {بُنْيان}، {صِنْوان}.

Exceptions are made from this rule are

  • يس * وَالْقُرْآنِ الْحَكِيمِ﴾ (يس 1-2) )
  • ن وَالْقَلَمِ وَمَا يَسْطُرُونَ﴾ (القلم 1)﴿

Merging – Idgham- without Gunna

It occurs when Noon sakin or tanween is followed by ل or ر.

  • (ن + ل) : {أَنْ لَوْ} {أنْداداً لِّيُضِلُّوا}, and they are recited ” الّو “, ” أندادَ لِّيضلوا “.
  • (ن + ر ): {مِنْ رَب} {بشرًا رسولاً}, and they are recited  مِرَّب ” بَشَرَ رَّسولاً
