An Easy Way For MemorizingIdgham Letters There is an easy way for learners to memorize Idgham letters. They can be memorized in the form of an Arabic word which is  (يرْمَلُون). 

There is another way which is to divide the six letters into two parts as follows: (لر ينمو)

The reason behind this division is the fact that this Arabic phrase divides the letters of Idgham into two types: Idgham with Ghunah and Idgham without Ghunah. Idgham with Ghunnah comes with the letters (ي ن م و), and Idgham without Ghunnah with the letters: (ل ر).

What is the Purpose of Idgham?

The purpose of idgham is to maintain the flow and rhythm of the recitation of the Quran. The Idgham of the letters specified above is to avoid any disruptions or abruptness in the pronunciation of these letters when joining together in the recitation. It is considered a beautification of the recitation when applied correctly according to the rules of Tajweed.

Mastering idgham is an important aspect of Tajweed for those who seek to recite the Quran with proper pronunciation and adherence to the rules of recitation.

When To Pronounce the Idgham in Tajweed?

 If the Arabic letter An-Noon Es-Sakinah or the Arabic linguistic sign which is called At-tanween is followed by any letter of the six Idgham letters that are mentioned above, then, both of An-Noon Sakinah or Tanween will be merged into this letter to form a new sound that stands in the middle between the two sounds of the main letters.

The stress or emphasis sound will be placed onto the succeeding letter because of the Arabic phonetic sign which is called Esh-Shaddah.

In order to make the concept of the Idgham term more obvious, we have to mention that Idgham only will happen when just two words come together – the first word ends with An-NoonEs-Sakinah or At-tanween, and the second word begins with one of the Idgham six letters.
