Introduction

Idgham (الإدغام), literally meaning “merging” or “assimilation,” is one of the essential rules in Tajweed science. This principle ensures the proper pronunciation of letters when they meet under specific conditions, contributing to the melodious flow and accurate recitation of the Holy Quran.

Understanding Idgham

Definition

Idgham occurs when two letters meet, and the first letter merges into the second, resulting in a stressed (mushaddad) second letter. This merging creates a seamless flow in pronunciation while maintaining the meaning and integrity of the Quranic text.

Categories of Idgham

1. Based on Noon Sakin and Tanween

• Idgham with Ghunnah (with nasalization)
• Idgham without Ghunnah (without nasalization)

1. Based on Letter Similarity

• Idgham Mutamathelain (identical letters)
• Idgham Mutajanisain (similar articulation points)
• Idgham Mutaqaribain (close articulation points)

Detailed Analysis of Each Type

1. Idgham with Noon Sakin and Tanween

A. Idgham with Ghunnah

Letters: يَنْمُو (Ya, Noon, Meem, Waw)

• Examples:
• مَنْ يَّقُولُ → Man Yaqulu
• مِنْ نِّعْمَةٍ → Min Ni’matin
• خَيْرٌ مِّنْ → Khairum Min
• عَذَابٌ وَّلَا → ‘Athabuw Wala

Duration: Hold the Ghunnah for 2 counts

B. Idgham without Ghunnah

Letters: ل، ر (Lam, Ra)

• Examples:
• مِن رَّبِّكَ → Mir Rabbika
• مِن لَّدُنْهُ → Mil Ladunhu

2. Idgham Mutamathelain (Complete Merging)

Definition: When two identical letters meet

• Examples:
• قَد دَّخَلُوا → Qad Dakhalu
• إِذْ ذَّهَبَ → Ith Thahaba
• اضْرِب بِّعَصَاكَ → Adrib Bi’asaka

3. Idgham Mutajanisain (Similar Letters)

Definition: When two letters share the same articulation point but differ in characteristics

• Examples:
• ب + م = م (Ba + Meem)
• ت + د = د (Ta + Dal)
• ت + ط = ط (Ta + Taa)

4. Idgham Mutaqaribain (Close Letters)

Definition: When two letters have close articulation points

• Examples:
• ل + ر = ر (Lam + Ra)
• ق + ك = ك (Qaf + Kaf)

Practical Application

Rules for Proper Implementation

1. Complete Merging

• First letter should completely merge into second
• No trace of first letter should remain
• Second letter becomes stressed

1. Ghunnah Application

• Must be clear and distinct
• Maintain proper duration (2 counts)
• Avoid over-extension

1. Stopping Rules

• If stopping at first letter, Idgham doesn’t apply
• Resume from second letter when continuing

Common Mistakes to Avoid

1. Incomplete Merging

• Partial pronunciation of first letter
• Weak stress on second letter
• Incorrect duration of Ghunnah

1. Over-application

• Applying Idgham where not needed
• Merging across word boundaries incorrectly
• Extending Ghunnah beyond 2 counts

1. Technical Errors

• Incorrect articulation points
• Wrong stress placement
• Improper breath control
