A learner recites أَلَمْ تَرَ كَيْفَ فَعَلَ رَبُّكَ and stretches the yaa of كَيْفَ while continuing into فَعَلَ. That is the mistake. The word contains a letter of leen, but the optional lengthening appears only when the reciter stops on كَيْفْ. Madd Leen is not a property of the word. It is a property of the moment you stop on it. This rule belongs to the Madd rules chapter of Tajweed rules.
Also written Madd Lin, Madd Layyin or Madd Layn, and sometimes called the soft madd — in Arabic, مد اللين. All one rule.
⚡ The 30-second version: two letters (وْ and يْ) · each preceded by a fathah · one letter after it · and you must be stopping on that word · then hold it 2, 4 or 6 counts, your choice. Keep reading and there is no lengthening at all. Everything on this page follows the riwayah of Hafs ‘an ‘Asim by the way of Ash-Shatibiyyah.
What Is Madd Lin in Tajweed?
Madd Leen (مد اللين) is the soft lengthening of a waw sakinah (وْ) or yaa sakinah (يْ) preceded by a fathah, when you stop on that word. It is held for 2, 4 or 6 counts. While you continue reading there is no lengthening, though the letter of leen is still pronounced softly.
The name is literal. Leen (لين) means softness and ease. The letter does not stretch the way a madd letter stretches — it glides. The name is describing the sound, not the length.
What makes this rule different from every other madd on the hub is conditional existence. Madd Asli, Madd Badal, Madd Muttasil — all of them exist the moment their letters exist on the page. Madd Leen exists only when the reciter chooses to stop. That is the whole rule in one sentence, and it is the part almost every English lesson leaves out.
One note on the unit before we go further: a count (harakah) is a relative timing unit based on the reciter’s own natural pace, not a fixed number of seconds. Opening or closing one finger is only a beginner training aid for feeling that pace — which is why two reciters at “four counts” can still sound slightly different and both be correct.
Madd Leen, Madd Lin or Madd Layyin: are they the same?
Yes — one rule, four transliterations of the same Arabic term مد اللين: Leen, Lin, Layyin and Layn. Classical books say leen; English courses split between lin and layyin; some translations simply write soft madd.
So if your teacher says one spelling and your book prints another, nothing has changed underneath. Same letters, same conditions, same counts.
The Madd Lin Letters: Just Two
There are two Madd Lin letters: و and ي. That is the entire list. Alif is never a leen letter — and there is a clean reason why, which we come to in a moment.
Alif is not included because the letters of leen are specifically a sakin waw or sakin yaa preceded by a fathah. Alif has its own fixed relationship with fathah as a madd letter. The answer to “are there three leen letters?” is no — there are two, and there is no fourth case hiding anywhere.
Leen letters vs madd letters: the vowel-match test
This is the single test that ends the confusion permanently, and it is one question long: does the vowel before the letter match the letter? If it matches, the letter stretches — it is a madd letter. If it does not match, the letter softens — it is a leen letter.
🔑 The takeaway: the letter never changes — the vowel before it decides what the letter becomes. The same waw sakinah is a madd letter in يَقُولُ and a leen letter in خَوْف. Once you hear that, you never confuse them again. The stretching version belongs to Madd Asli.
The Madd Lin Rules and Conditions
Three conditions, and every one of them has to hold at the same time. The Madd Lin Tajweed rule is only in force when all three are true together.
1 · There is a leen letter
A و or ي, sakinah, with a fathah on the letter before it.
✅ خَوْف ❌ يَقُول — dammah before the waw, so that is a madd letter
2 · The letter after it is the last letter of the word
Exactly one letter follows the leen letter — no more.
✅ قُرَيْشٍ ❌ عَلَيْهِمْ — two letters follow the yaa, so no madd leen, ever
3 · You are stopping on that word
This is the condition that gets dropped, and dropping it is what makes people recite the rule wrong for years.
✅ stopping on خَوْفٍ ❌ continuing through خَوْفٍ — the leen letter is simply pronounced softly, with no length at all
Hear the difference: the same word, stopped and continued
Teacher recordings made for this lesson. Same word, opposite result — then the same test on كَيْفَ.
Tap a line to hear it.
⚠️ All three must hold together. Drop the third and the rule disappears completely. Madd Leen is the only madd in the chapter that vanishes when you keep reading. There is one exceptional case — the letter عَيْن in two surah openings — and it has its own section below.
How Many Counts Is Madd Lin?
Madd Lin is 2, 4 or 6 counts, and the reciter chooses. The three lengths have names your teacher will say out loud but you will rarely see printed in English material: qasr (قصر, 2 counts), tawassut (توسط, 4 counts) and tul (طول, 6 counts).
Three rows on purpose. The full counts table for every madd type lives on the Madd rules hub.

خَوْفْ
2 counts · qasr
خَوْفْ
4 counts · tawassut
خَوْفْ
6 counts · tul
Whichever length you choose, keep it for the whole session — and many teachers have beginners keep it matched with their Madd ‘Arid lis-Sukoon. Switching between two counts at one ayah-end and six at the next is the single most audible mark of an untrained reciter, and it is a mistake almost nobody is told about in English.
Many teachers ask beginners to take two counts everywhere until their stops are stable, and only then move up to four or six. That is good advice: consistency at two is worth far more than an impressive six that wanders.
How to Pronounce Madd Lin
The sound is a glide, not a stretch. Feel the difference in your own mouth. In يَقُولُ the mouth locks into one position and stays there for the whole length — nothing moves. In خَوْفٍ the mouth travels from the fathah toward the waw, and then rests. That travel is precisely what the word leen is naming.
Madd Lin pronunciation: three details that fix it
No ghunnah, no pitch rise, no wobble. The held part is level and relaxed. If you hear a hum through the nose, that is a different rule leaking in.
English starting points, not targets. خَوْف sits near the vowel in “how”, and بَيْت near the vowel in “bite”. Use them to find the shape of the mouth, then take the actual sound from the reciter — never from English.
The six-count trap. At six counts learners re-open the mouth in the middle of the hold and produce aa-oo-f. The glide happens once, at the very start. Everything after it is one steady, unmoving position.
خَوْفٍ
Quraysh 106:4 · the glide, then the hold
نَسْتَعِيْنُ
Al-Fatihah 1:5 · a pure, level stretch — no travel at all
Play them back to back. Side by side the difference is obvious; in isolation it is almost inaudible — which is exactly the learner’s problem.
The same test on الْبَيْت, in the teacher’s voice: stopped, then continued.
الْبَيْتْ
Stopped · Madd Leen is lengthened — 2 counts here
الْبَيْتِ
Continued · the yaa is still a letter of leen, with no lengthening
Madd Lin vs Madd Arid Lis-Sukoon
If you already know both names and still cannot tell them apart, you are in the right place — and the reason is simple. Madd Lin and Madd Arid Lis-Sukoon share almost everything.
The verdict: they share the same temporary cause and the commonly taught 2, 4 and 6-count options, but they differ in the type of letter being lengthened. Keeping both at the same length — four counts for your Madd ‘Arid lis-Sukoon and four for your Madd Leen — is useful beginner practice for a steady recitation.
Madd Lin Examples in the Quran
Surah Quraysh is the best training surah in the Quran for this rule. Three of its four ayat end on a leen letter, the fourth ends on the showcase waw, and almost every learner already knows it by heart — which makes it the fastest possible proof. Tap any word below to hear it in Sheikh Al-Husary’s voice. Words outlined in gold carry the leen letter.

Every word is a clip from Al-Husary’s recitation of that ayah. Tap a gold word twice — once here, once in your own mushaf.

Madd Lin words to practise
A word bank you can drill away from the mushaf, split by letter.
Yaa يْ after a fathah
بَيْت · شَيْء · كَيْف · خَيْر · غَيْب · صَيْف · قُرَيْش · رَيْب · عَيْن · بَيْن
Waw وْ after a fathah
خَوْف · يَوْم · قَوْم · لَوْن · نَوْم · مَوْت · صَوْت · طَوْع
⚠️ None of these words has madd leen on its own. Each one becomes a madd leen only when you stop on it. Read any of them in the middle of a phrase and there is no lengthening at all — the letters of leen are always there, the madd is not.
The Exceptional Case: ‘Ayn in Two Surah Openings
There is one exceptional case where Madd Leen is obligatory rather than optional — and it occurs in the disconnected letters that open two surahs.
The letter عَيْن, which appears in كهيعص at the opening of Surah Maryam and in عسق in Surah Ash-Shura, is spelled ع – يْ – ن: a leen letter followed by a permanent sukoon, not a temporary one. Because the sukoon does not come from your decision to stop, your decision cannot remove it.
So the usual 2-4-6 choice does not apply. Two lengths are transmitted in this route — four counts or six, whether you stop or continue — with six commonly presented as the preferred and more widely taught performance. This is the one case where the ordinary Madd Leen choice is not yours to make.
كهيعص
Surah Maryam 19:1 · listen for the length on the عَيْن
عسق
Surah Ash-Shura 42:2 · the same length, in a shorter opening
The wider family of permanent-sukoon madds — and the four types it splits into — is covered on Madd Lazim.
6 Common Madd Leen Mistakes
1 · Stretching it while continuing
The single most common error, and the reason most people learn this rule wrong in the first place. خَوْفٍ in the middle of a phrase gets no length whatsoever.
2 · Calling it a madd because the letter looks like one
يَقُولُ and خَوْف share a waw sakinah — and nothing else. Run the vowel-match test instead of trusting the shape.
3 · Changing the count from stop to stop
Two counts at one ayah-end and six at the next. Pick one length at the start of the session and hold it.
4 · Using a different length for Leen than for ‘Arid
Keeping them matched is useful beginner practice: two rules with the same temporary cause and the same options are far easier to hold steady when you give them the same length.
5 · Re-opening the mouth mid-hold
At four or six counts this produces aa-oo-f instead of one steady glide-and-hold. The glide happens once, at the start.
6 · Treating عَيْن in the surah openings as optional
It is the exceptional case, in two surah openings: the ordinary 2-4-6 choice does not apply there. Four counts and six are both transmitted, with six the preferred and more widely taught — stopping or continuing.
Practise Madd Leen
Consistency trainer: pick a length and hold it
Accuracy is not the skill here — consistency is. Choose your length, then recite five stops in a row, pressing and holding the bar for each one. The score you get back is how much your five holds varied, not how close they were to a stopwatch.
Hold 0 of 5. Recite a leen stop out loud while you hold.
A guide, not a ruling: counts are relative to your own pace. What matters is that your five holds match each other. This trainer measures consistency, not the religious validity of your timing. A qualified teacher should assess the actual recitation.

Read these four in order and the whole madd chapter falls into place. Madd Asli is the two-count baseline everything else is measured against; Madd Badal is a hamzah before the madd letter and stays at two; Madd Wajib Muttasil is a hamzah after it in the same word and is obligatory at four to five; Madd Silah is the pronoun’s ha’, short at two or long at four to five before a hamzah. Madd Leen sits outside this group precisely because it is the only one that depends on where you stop.
