Idgham Saghir in Tajweed With Examples

Idgham Saghir in Tajweed is one of the essential rules that helps Quran reciters achieve a smoother and more accurate pronunciation. It explains how a sakin letter merges into the following voweled letter across two words, creating a single emphasized sound during recitation.

In this guide, you will learn the meaning of Idgham Saghir, its three types (Mutamathhilayn, Mutajanisayn, and Mutaqaribayn), Quranic examples, the difference between complete and incomplete merging, and the key exception that prevents this rule from applying inside a single word. By understanding these principles, you can recognize Idgham Saghir in the Mushaf and apply it correctly in your Quran recitation.

What Is Idgham Saghir?

Idgham Saghir is the merging of a sukoon (stationary) letter into the voweled letter that immediately follows it across two adjacent words, so that both become a single doubled letter.

It is called Saghir (minor) because the first letter already carries a sukoon, requiring less effort to merge than stopping a moving letter would. In the Mushaf, this is marked by removing the sukoon from the first letter and placing a shaddah on the second.

The Three Types of Idgham Saghir

The classification is based on the phonetic relationship between the two merging letters.

1. Idgham al-Mutamathhilayn 

Idgham al-Mutamathhilayn إدغام المتماثلين occurs with two letters that are identical in name, articulation point, and characteristics. Example: ﴿رَبِحَت تِّجَارَتُهُمْ﴾ — the Ta merges into the Ta, producing one emphasized Ta.

2. Idgham al-Mutajanisayn

Idgham al-Mutajanisayn إدغام المتجانسين occurs with two letters sharing the same articulation point but differing in some characteristics. Example: the Ta (ت) merging into the emphatic Ta (ط) in ﴿لَئِن بَسَطتَ﴾.

3. Idgham al-Mutaqaribayn

Idgham al-Mutaqaribayn occurs with two letters close — but not identical — in articulation point or characteristics. Key pairs: Lam into Ra ﴿بَل رَّفَعَهُ﴾, and Qaf into Kaf ﴿أَلَمْ نَخْلُقكُّم﴾. One important practitioner note: the Qaf does not carry Qalqalah in this merge, since it has lost its identity into the Kaf — a common error among intermediate students.

Idgham Kamil (Complete) vs. Idgham Naqis (Incomplete)

The main difference between Idgham Kamil (Complete Idgham) and Idgham Naqis (Incomplete Idgham) is whether the first letter disappears completely or leaves behind some of its characteristics. 

In Idgham Kamil, the first letter is fully absorbed into the following letter, losing both its sound and attributes. In Idgham Naqis, the letter’s sound disappears, but one of its characteristics — such as ghunnah or an emphatic quality — remains audible.

Idgham Kamil (Complete): the first letter disappears in both identity and characteristics. Example: ﴿أُجِيبَت دَّعْوَتُكُمَا﴾ — the Ta vanishes entirely.

Idgham Naqis (Incomplete): the letter’s sound disappears but a residual characteristic remains. This occurs in four cases — Nun merging into Waw or Ya (ghunnah remains), and Ta merging into ط or Qaf merging into Kaf (emphatic characteristics remain). The Ta and Qaf also carry no Qalqalah in these merges.

Idgham Saghir vs. Idgham Kabir

The main difference between Idgham Saghir and Idgham Kabir is the condition of the letters before merging and where each type is commonly found in recitation. 

Idgham Saghir occurs when a sakin letter merges into the following voweled letter across two words and is widely applied in Hafs recitation.

Idgham Kabir occurs when two voweled letters meet, requiring the first letter to become sakin before merging, and is mainly found in specific Qira’at such as the narration of Imam Abu Amr.

The Exception You Must Know

Idgham Saghir never applies inside a single word. Words like الدُّنْيَا and بُنْيَانٌ are read with a clear Noon — not merged — because both letters belong to the same word. Always confirm the letters span two separate words before applying the rule.

Conclusion

Idgham Saghir merges a sukoon letter into the voweled letter that follows it, across two words, producing one doubled sound. Its three types cover identical, same-origin, and phonetically close letter pairs. Merging can be complete or partial depending on whether residual characteristics carry over. The rule never applies within a single word. With this foundation in place, you will begin to recognize Idgham Saghir naturally throughout your recitation.
