Madd Leen

When you recite the Quran and pause at the end of a verse, certain words carry a gentle, flowing softness before the silence. That quality comes from madd leen—one of the most elegant yet frequently misunderstood extensions in Tajweed, and the final madd in the complete system of nine Quranic extensions.

Madd leen applies specifically to the letters Waw and Ya when they appear as leen letters—sukoon with a fatha before them—followed by a letter that receives temporary sukoon at the point of pausing. It is defined, measured, and governed by precise scholarly rules that every serious reciter must internalize.

What is Madd Leen?

Madd leen is the extension applied to a leen letter—either a sukoon Waw or sukoon Ya preceded by a fatha—when the letter immediately following it receives an ‘arida (temporary) sukoon due to pausing. It is measured at 2, 4, or 6 harakaat, identical in scope to Madd ‘Aridh lis-Sukoon.

The foundational distinction you must grasp is the difference between a harf madd and a harf leen. 

The Difference Between a Harf Madd And a Harf Leen

A harf madd requires a precise vowel match: sukoon Alif needs a fatha before it, sukoon Waw needs a damma before it, and sukoon Ya needs a kasra before it. 

A harf leen, however, breaks this pattern—both the sukoon Waw and sukoon Ya take a fatha before them instead of their matching vowel.

This fatha before both letters is precisely what earns them the name “leen”—meaning softness or ease. The letters exit the articulation point with natural lightness and flow, without effort or constriction. Scholars of Tajweed note that this smooth, effortless exit is what distinguishes leen from madd.

Working through madd leen examples in Quran carefully with a qualified teacher accelerates accurate identification. At Learn Quran Tajweed Academy, our Intermediate Tajweed Course covers this rule alongside all nine Quranic extensions with certified Qaris in focused 1-on-1 sessions.

Leen Letters Examples

The leen letters appear constantly throughout the Quran. Identifying them correctly is your first practical skill before applying any extension.

Consider these clear leen letters examples from common Quranic vocabulary:

Word	Leen Letter	Letter Before It	Condition Met?
خَوْف (Khawf)	Waw (ساكنة)	Kha (مفتوح)	✅ Yes
بَيْت (Bayt)	Ya (ساكنة)	Ba (مفتوح)	✅ Yes
قَوْم (Qawm)	Waw (ساكنة)	Qaf (مفتوح)	✅ Yes
الصَّيْف (As-Sayf)	Ya (ساكنة)	Sa (مفتوح)	✅ Yes
اللَّيْل (Al-Layl)	Ya (ساكنة)	La (مفتوح)	✅ Yes

If the Waw carries a damma before it—as in نُوْر—it becomes a harf madd, not a harf leen. If the Ya carries a kasra before it—as in دِيْن—it is equally a harf madd. The fatha before both is the non-negotiable condition for leen.

Madd Leen Types

The classical scholars of Tajweed and recitation divided madd leen into two types based on what follows the leen letter within the word. Understanding madd leen types protects you from applying the rule incorrectly.

1. Madd Leen Ghayr Mahmuz

This is the more common of the two types. Here, the leen letter is followed by any regular consonant that receives temporary sukoon upon pausing. The overwhelming majority of madd leen examples in Quran fall into this category.

A clear example is the word خَوْف in Surah Quraysh. The Waw carries sukoon, the Kha before it is open with fatha, and the Fa at the end receives temporary sukoon when you pause. All three conditions of madd leen are present.

خَوْفٍ
Khawf
“Fear” (Quraysh 106:4) 

Madd Leen Ghayr Mahmuz: Waw saakinah, preceded by fatha, followed by temporary sukoon on Fa at pause

2. Madd Leen Mahmuz

This type requires a hamza to immediately follow the leen letter within the same word. The hamza receives temporary sukoon upon pausing, triggering the extension.

A precise example is شَيْء found repeatedly throughout the Quran, including Surah Al-Baqarah. The Ya carries sukoon, the Sha before it carries fatha, and the Hamza at the end receives temporary sukoon upon pausing.

شَيْءٍ
Shay’
“Thing / Anything” (Al-Baqarah 2:20)

Madd Leen Mahmuz: Ya saakinah, preceded by fatha, Hamza receives temporary sukoon upon pausing

Similarly, السَّوْء in Surah Al-Fath and تَيْأَسُوا in Surah Yusuf both demonstrate madd leen mahmuz in context.

Madd Leen Examples

Surah Quraysh provides two clear madd leen examples within four short verses. The word خَوْفٍ (fear) contains a leen Waw, and قُرَيْشٍ itself contains a leen Ya in the word قُرَيْش—the Ya is sukoon with fatha before it.

لِإِيلَافِ قُرَيْشٍ
Li-īlāfi Quraysh
“For the accustomed security of the Quraysh.” (Quraysh 106:1) 

Madd Leen: Ya saakinah in Quraysh, preceded by fatha on Ra, Shin receives temporary sukoon at pause

Surah Al-Fajr, Surah Al-Layl, and Surah Al-Balad are rich with leen letters throughout. Developing a habit of marking leen letters in your personal Mushaf during study—distinct from harf madd markings—trains your eye before your tongue.

Madd Leen Aridh

One of the most important analytical distinctions in the nine Quranic extensions is understanding precisely how madd leen aridh differs from Madd ‘Aridh lis-Sukoon. Both rules share significant structural similarities, yet they are categorically separate.

Feature	Madd ‘Aridh lis-Sukoon	Madd Leen (‘Aridh)
Extension Letter	Harf Madd (Alif/Waw/Ya with matching vowel)	Harf Leen (Waw or Ya with fatha before them)
Sukoon Type	Temporary (‘Arida)	Temporary (‘Arida)
Condition	Pausing at end of word	Pausing at end of word
Duration	2, 4, or 6 harakaat	2, 4, or 6 harakaat
Permissibility	Waqf only	Waqf only

The definition of madd leen aridh in classical Tajweed texts reads: a leen letter followed by a letter that receives temporary sukoon due to pausing. This mirrors the definition of Madd ‘Aridh almost word for word—only the type of extension letter changes.

This parallel structure is intentional. The scholars recognized that both rules share the same condition (‘arida sukoon through waqf) while differing in their foundational letter. Understanding madd aridh examples alongside madd leen examples reinforces both rules simultaneously.

How to Learn Madd Leen?

The rule only activates at waqf—pausing—which means you must develop the instinct to recognize leen letters in real time before reaching the end of a word.

The three permissible durations—2 harakaat (qasr), 4 harakaat (tawassut), and 6 harakaat (tul)—are all valid for all reciters in the narration of Hafs ‘an ‘Asim. 

Consistency within a single recitation session matters: choose one duration and maintain it throughout unless your teacher instructs otherwise.

A common error among students is extending madd leen during wasl (continuous recitation without pausing). In wasl, the leen letter is read with its natural 2-harakaat length only, with no extension whatsoever. The Tajweed rule is suspended entirely during connection.

Another frequent mistake is confusing leen letters embedded in words with harf madd letters. In خَوْف, students sometimes read the Waw as carrying a damma and treat it as madd tabee’i. Hearing it correctly from an Ijazah-certified instructor corrects this immediately.

Learn Quran Tajweed Academy’s Practical Tajweed Course is specifically designed to bridge this gap—taking students from theoretical rule knowledge to accurate application in actual recitation through structured audio feedback sessions.

Madd Leen Lazim Examples

A leen or madd letter followed by a letter with original sukoon due to idghaam (merging/doubling) within a single word. The word “lazim” signals that the extension is obligatory and fixed for all reciters at a mandatory 6 harakaat without variation.

The madd leen lazim examples in Quran for this category are limited and precise. Two notable instances occur in the isolated letter عَيْن (ع) at the opening of Surah Maryam (19:1) and Surah Ash-Shura (42:2). 

The Ya in عَيْن is a leen letter, and the Nun following it carries original sukoon as part of the letter’s name—making this Madd Lazim Harfi Shabih bil-Muthaqal (Obligatory Lettered Extension Resembling the Heavy).

The term “Shabih bil-Muthaqal” (resembling the heavy) is used here because the hidden idghaam-like quality—specifically the ghunnah—introduces a degree of weight in pronunciation, even though it is not a full tashdid.

A pure madd leen lazim example within a full word is found in الضَّآلِّين from Surah Al-Fatiha, though in this case the extension precedes the shaddah through the Alif rather than a leen letter. 

For leen specifically, the ‘ayn of Maryam and Ash-Shura remain the most referenced madd leen lazim examples cited by scholars.

Conclusion

Madd leen stands apart as the only Quranic extension built on harf leen rather than harf madd, yet its ‘aridh form operates under the same waqf conditions and the same 2/4/6 harakaat flexibility as Madd ‘Aridh lis-Sukoon. Both types—mahmuz and ghayr mahmuz—require careful identification before pausing.

The lazim dimension of madd leen, particularly the isolated letters ‘Ayn in Maryam and Ash-Shura, introduces a fixed 6-harakaat obligation that distinguishes it from the permissible flexibility of the ‘aridh form. Accurate application depends on distinguishing original sukoon from temporary sukoon every time.

Consistent practice with a qualified instructor remains the only reliable path to internalizing madd leen across varied Quranic contexts. Alhamdulillah, the scholars preserved these rules in precise detail so every reciter—regardless of background—can honor the Quran as it was revealed.
