Idgham literally means merging one thing into another.
Technically: a sukoon letter merges into a moving letter, becoming one doubled (shaddah) letter.
Idgham with Ghunnah occurs before four letters, memorized as: "yanmoo" (يَنْمُو)
Ya (ي), Noon (ن), Meem (م), Waw (و)
Example: "مِن يَقُولُ" → becomes "مِيَّقُولُ" — noon merges into ya with ghunnah.
Important condition: No Idgham when both letters are in the same word (like "dunya" and "qinwan")
