Question

When we stop on a word we stop with a sukoon.  If the letter we stop on had a vowel on it and the letter before the saakin letter is a mad letter we now lengthen the medd letter either 2 or 4 or 6 counts.  My question is if the letter before the last letter is a leen letter is the count the same? 

Answer

You are correct, Arabs always stop with a sukoon, and always start with a vowel.  If there is a medd letter ( , , or ) just before the last letter of the word, and the last letter has a vowel on it, we stop on that last letter with a presented sukoon, and lengthen the medd letter 2, 4, or 6 counts, such as stopping on the word: .  This medd is called , or presented sukoon lengthening.

If there is a leen letter (a  saakinah or a  saakinah preceded by a fat-h) just before the last letter of the word, and the last letter of the word has a vowel, we stop on the last letter with a presented sukoon and lengthen the leen 2, 4, or 6 counts.  An example of this would be stopping on the word:  or the word .  In both cases there is a leen letter just before the last letter of the word, in the example of , the last letter is a , and in the example of , the last letter is a .  We stop on both with a presented sukoon and lengthen the leen letter, 2, 4, or 6 vowel counts. 

The leen medd has to be equal or less than the  (presented sukoon lengthening).  In other words, if we stop on the word  and all similar presented sukoon mudood with 4 counts, we can lengthen the leen medd 2 or 4, but never six vowel counts.  If we stop on  with two vowel counts, we can only stop on a medd leen with two vowel counts.
