What is Tajweed?
The word tajweed (تجويد) means "to make well" or "to beautify." In the context of the Quran, it is the science of pronouncing each Arabic letter correctly — from its proper articulation point — and applying the rules that govern how letters behave next to one another. The Quran was revealed with these rules, received by the Prophet Muhammad ﷺ from the angel Jibril and passed down, generation to generation, exactly as recited.
Allah says: "…and recite the Quran with measured recitation" (Surah al-Muzzammil 73:4) — the word used, tartil, is the very foundation of tajweed. Reciting with tajweed preserves the Quran's meaning (a mispronounced letter can change a word entirely), protects the text from distortion, and is the way the Prophet ﷺ and his companions recited.
Noon Sakinah and Tanween
A noon sakinah is the letter نْ (noon with a sukoon, no vowel). Tanween is the doubled vowel ending (ـً ـٍ ـٌ) that sounds like an "n" at the end of a word. Both are governed by the same four rules, decided by whichever letter comes next:
Izhar إظهار — clear pronunciation
When the noon sakinah or tanween is followed by one of the six throat letters (ء هـ ع ح غ خ), the "n" sound is pronounced clearly, with no change and no nasal hum.
Example: مِنْ خَوْفٍ — the n in min is said plainly.
Idgham إدغام — merging
Before the letters grouped in the word يَرْمَلُونَ (ي ر م ل و ن), the noon sound merges into the following letter. With ي و م ن it merges with a nasal hum (ghunnah); with ل ر it merges without ghunnah.
Example: مَنْ يَقُولُ — read as "may-yaqoolu," the noon blending into the ya.
Iqlab إقلاب — conversion
When followed by the single letter ب (ba), the noon sound is converted into a hidden meem (م) sound with a light nasal hum.
Example: مِنْ بَعْدِ — pronounced "mim-baʿdi."
Ikhfa إخفاء — concealment
Before the remaining fifteen letters (all those not covered above), the noon sound is partly hidden — pronounced lightly between clear and merged, with a nasal hum held for about two counts.
Example: مِنْ قَبْلِ — the noon is softened as the mouth prepares for the qaf.
Meem Sakinah
A meem sakinah is the letter مْ (meem with a sukoon). It has three rules depending on the next letter:
| Rule | When it applies | How to recite |
|---|---|---|
| Ikhfa Shafawi إخفاء شفوي |
Followed by ب (ba) | Hide the meem lightly with a nasal hum. E.g. تَرْمِيهِمْ بِحِجَارَةٍ |
| Idgham Shafawi إدغام شفوي |
Followed by another م (meem) | Merge the two meems into one with a nasal hum. E.g. لَهُمْ مَا |
| Izhar Shafawi إظهار شفوي |
Followed by any other letter | Pronounce the meem clearly, especially before ف and و. |
Shafawi means "of the lips," because the meem is articulated by closing the lips.
Madd — elongation
Madd (مدّ, "to stretch") is the lengthening of a vowel sound. It occurs with the three "letters of madd" — ا (alif), و (waw), and ي (ya) — when preceded by their matching vowel. There are two broad types:
- Madd Tabee'i (natural madd): the basic elongation, held for two counts. Example: قَالَ (qāla).
- Madd Far'ee (secondary madd): a longer elongation caused by a hamza (ء) or a sukoon following the madd letter, held for around four to six counts depending on the case. Example: جَاءَ (jāʾa) and وَلَا الضَّالِّينَ.
Consistency of the count within a recitation matters more than an exact number; a teacher will set the measure for you.
Qalqalah — echoing
Qalqalah (قلقلة, "to shake") is a slight bouncing or echoing sound made when one of five letters carries a sukoon or is stopped upon. The five letters are gathered in the phrase قُطْبُ جَدٍّ — ق ط ب ج د.
The echo is stronger when the letter falls at the end of a word you stop on, and lighter in the middle of a word.
Example: قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ — the ق at the end of al-falaq is given a clear bounce.
Makharij — the articulation points
Underlying every rule above is the makhraj (plural makharij, مخارج الحروف) — the precise point in the mouth, throat, or lips from which each letter is produced. Classical scholars identify seventeen articulation points across five regions: the empty space of the mouth and throat, the throat itself, the tongue, the lips, and the nasal passage.
Makharij matter because several Arabic letters sound similar to an untrained ear but come from different points — for example ح and هـ, or س, ص, and ث. Confusing them can change a word's meaning entirely. Alongside the makhraj, each letter has sifat (characteristics, such as heaviness or lightness) that complete its correct sound. Mastering these is the true foundation of tajweed — and the clearest reason it must be learned by listening to a teacher.
