is a question among us regarding the formation of the leen letters: we
have read in the book of Tajweed Rules of the Qur'an that the leen letters as
well as the medd letters are formed by vibration in the vocal chords.
One teacher thought that she had learned that they were emitted by either
pressing on the makhraj of Ya for the ya leeniya or by the rounding of the
lips in the case of the wow leeniya which would mean that they are
pronounced by (that is by collision) of the
articulation parts. We would be grateful if you could please enlighten
us in this matter insha’ Allah.
are two states for (the leen). In
one case there is a leen letter followed by one or more letters in the same
word, and we are not stopping on the word with a medd leen.
This is called a leen letter. In
this case, there is a weak , or
collision, between the two parts of articulation in addition to vibration of
the vocal cords in the throat. There would be then
some mild pressure during the collision on the two lips in
the case of the
articulation point), and pressure on the articulation point of the
performing the collision of this letter, but the vibration of the vocal cords
overwhelms the formation of the sound of the leen letter.
second case of leen is when there is a leen letter, meaning
with a fath before it, there is only one voweled letter following it, and we
are stopping on the word. This is
medd al-leen, which is lengthened 2, 4, or 6 vowel counts.
In the case of medd al-leen, the mechanism of formation is the same as
the medd letters: vibration of the vocal cords with the accompanying circling
of the lips for the
and lowering of the jaw for the
