If you can read the Quran but you were never taught tajweed properly, this is the article for you. It walks through the main rules in the order they usually get taught, in plain English, with the Arabic where the Arabic is the point.
One thing worth saying first. Tajweed is not decoration added to recitation. It is the pronunciation the Quran was revealed with, and most of it is about giving each letter its correct sound and its correct length. Almost every rule below is really an instruction about your mouth.
Start with the letters, not the rules
Before any named rule, there is makharij: the point in the mouth or throat where each letter is made.
Most mistakes non-native readers make are makharij mistakes, not rule mistakes. The classic pairs:
- س and ص: both an s sound, but ص is heavy, made with the tongue low and the mouth full.
- ت and ط: both a t, but ط is heavy and made further back.
- ذ, ز and ظ: three different sounds that collapse into one z for many readers.
- ح and ه: both breathy, made at different depths of the throat.
- ق and ك: both a k, but ق comes from the back of the tongue against the soft palate.
No article fixes these, because you cannot hear yourself the way a listener hears you. This is the part that needs a teacher, and it is worth sorting out before the named rules, because the rules are applied to these letters.
Ghunnah, the sound behind several rules
Ghunnah is a nasal sound, held for about two counts, that comes out of the nose rather than the mouth. It is always present in نّ and مّ (a noon or meem carrying a shadda), and it shows up inside several of the rules below.
If you can hum, you can make a ghunnah. Pinch your nose while making it and the sound should stop. That is the test.
The four rules of noon saakinah and tanween
This is the largest family of rules, and the one most people mean when they say “tajweed rules”. A noon saakinah is a ن with a sukoon on it. Tanween is the doubled vowel ending: ـً ـٍ ـٌ. Both behave the same way, and what happens depends entirely on the letter that comes next.
1. Izhar: say it clearly
When the next letter is one of the six throat letters, ء ه ع ح غ خ, the noon is pronounced plainly. No merging, no nasal hold.
2. Idgham: merge it into the next letter
When the next letter is one of six, ي ر م ل و ن, the noon merges into it. Teachers usually teach these as the word yarmaloon.
These split in two:
- With ghunnah, before ي ن م و: the merge carries the nasal sound for two counts.
- Without ghunnah, before ل and ر: the noon disappears into the letter cleanly, with no nasal hold.
3. Iqlab: turn it into a meem
When the next letter is ب, the noon turns into a meem sound with ghunnah. Your lips come together lightly where you were expecting an n.
4. Ikhfa: hide it
Everything else. Before the remaining fifteen letters, the noon is neither pronounced clearly nor fully merged. The tongue does not quite reach its usual position and the sound is held nasally for about two counts.
Ikhfa is the most common of the four, and the one most often skipped by readers who were never formally taught. If your recitation moves straight from an n to the next letter with no nasal hold, this is probably what is missing.
The three rules of meem saakinah
A meem with a sukoon, مْ, has a smaller set of rules.
- Ikhfa Shafawi: before ب, the meem is hidden with ghunnah, lips lightly touching.
- Idgham Shafawi: before another م, the two merge with ghunnah.
- Izhar Shafawi: before anything else, the meem is pronounced clearly. Watch it especially before و and ف, where lips are already involved and the meem tends to blur.
Madd: how long to hold a sound
Madd means elongation. The natural madd, madd asli, is held for two counts and happens whenever a madd letter (ا و ي) follows its matching vowel with nothing else acting on it.
Then there are longer madds, where something follows the madd letter that stretches it further: a hamza, or a sukoon. Depending on which, these run to four, five, or six counts, and schools of recitation differ slightly on the exact number.
The practical point for most readers is simpler than the categories: be consistent. Pick your count for each type and hold it the same way every time. Recitation that stretches a madd to five counts in one verse and two in the next is more noticeable than recitation that is uniformly a little short.
Qalqalah: the echo
Five letters carry a slight bounce or echo when they have a sukoon on them: ق ط ب ج د. Teachers teach them with the phrase qutb jad.
You hear it most clearly at the end of a verse. The د at the end of أَحَدْ in Surah al-Ikhlas is a qalqalah. The sound does not just stop, it rebounds slightly.
The common mistake is overdoing it, turning the echo into a full extra vowel. It is a bounce, not a syllable.
Heavy and light letters
Some letters are always heavy, pronounced with the mouth full and the back of the tongue raised: خ ص ض ط ظ غ ق. Everything else is light, with two letters that change depending on context:
- ر is heavy or light depending on the vowel on it and around it.
- ل is light almost everywhere, and heavy in the name اللّٰه when preceded by a fatha or damma.
Getting heavy and light right is what makes recitation sound settled rather than flat, and it is closely tied to makharij, which is why it is usually taught alongside.
Which order to learn these in
If you are starting from scratch as an adult who already reads:
- Makharij first. Fix the letters themselves before applying rules to them.
- Ghunnah, because several later rules depend on it.
- Noon saakinah and tanween, the four rules, in the order above.
- Meem saakinah, which is quick once the first four are solid.
- Madd, starting with the natural two-count madd and adding the longer ones.
- Qalqalah and heavy and light letters, which polish everything else.
Most students working consistently get through this sequence in a year to two years, depending on where they start. It goes faster than people expect, because the rules are few. What takes the time is applying them without thinking, at reading speed.
The honest limit of an article like this
You can memorize every rule above in an afternoon and still recite incorrectly. Tajweed is a listening subject.
You cannot hear your own ikhfa. You cannot tell from inside your own head whether your ص is genuinely heavy or whether you are making a slightly tense س. You cannot judge whether your madd is two counts or one and a half. All of that needs an ear other than yours, ideally one that has heard the mistake a thousand times and knows what usually causes it.
That is the whole reason tajweed has always been taught out loud, person to person, rather than from a book.
