Dear sir,

 The Separate Allowed Lengthening: you said that its lengthening is of the measure of four or five vowel counts in the: Hafs ‘an Aasim by the way of Shaatabiyyah. PLEASE I want to know which way transmitted by Hafs ‘an Aasim that has TWO VOWEL COUNTS for this lengthening.
Many thanks in advance.

Assalaam alaikum,
In Tareeq at-Tayyibah outlined by Imam Ibn Al-Jazaree in An-Nashr, there is a way for Hafs 'an 'Aasim that has two vowel counts for the medd al-jaa'iz al-munfasil (separate allowed lengthening) while having four vowel counts for the medd al-waajib al-mutasil (joined required lengthening).  This way is Al-Hammamee as documented in Al-Misbah min tareeq al-Feel. 

For the set of rules for reading this way, please see:

You are most welcome.
