Assalamu Aleikum wa rahmatu lilahi wa barakatuh
In question # 270205 you mentioned the imaalah and taqtîl. Would you please tell us:
1) What is the definition of imaalah and taqlîl?
2) Does the recitation of Hafs have any imaalah and taqlîl?
3) Does the recitation of khalaf al hamzah have a taqlîl slightly different from that of Warsh an Nâfi?
Shukran Jazilan
May Allah facilitate your work inshallah

Answer
Wa alaikum assalaam wa rahmatullahi wa barakatuh.
1. Imaalah is divided into to subgroups:
A. Grand Imaalah, which is when an alif is read as 50% 
and 50% alif
B. Lesser Imaalah ( 
) in which the alif is read as 25% and 75% alif.
2. Hafs reads only one word in the whole Qur’an with imaalah, and that is 
in aayah 41 of surah Hud. The recitation of Hafs reads this word with the grand imaalah. There is no in the recitation of Hafs ‘an ‘Aasim.
3. The recitation of Hamzah 
and Al-Kisaa’ee 
have required grand imaalah on most of the words that Warsh has possible taqleel ( ), such as words ending with an alif written as a , exemplified in the word: 
. Warsh is known for , but it is one of two allowed ways that Warsh has of reading most of the words that are read with complete imaalah in the recitation of Hamzah and Al-Kisaa’ee, the other allowed way for Warsh for most of these words is with no imaalah at all.
There are some words the Warsh has required while Hamzah and Al-Kisaa’ee have grand imaalah, such as a word ending with an alif maqsoora after a 
, exemplified in the word 
. There are still other words in which Warsh has required but Hamzah and Abu Al-Haarith ‘an Al-Kisaa’ee do not have any imaalah, such as a word ending with a with a kasrah preceded by an alif, such as: 
.
You are most welcome. Jazaka Allahu khairan for your dua’.
