Assalamu aleikum wa rahmatu lilahi wa barakatuh

I have a couple of questions regarding a few rules of the recitation of Ad Duri from Kesai. I was listening to surah Al Balad and Al Ghashiyyah by the way of Ad Duri from Kesai (www.islamweb.net the reciter was Abdur Rasheed Soofi) and I noticed that
when there is a word ending with a "Taa marbootah" such as the word "Masfuufah" (surah 88 verse 15), the reciter recited as "Masfuufe" except for the word "khaashi'a" (surah 88 verse 2) which he read as "khaashi'ah"

A. What is the name of this way of stopping with name ending in "taa marbuutah"?

Secondly, in the same surah (88 verse 23) the reciter read with an imalah the word "tawala". However that imalah sounded different from the other imalah I know such as in Warsh.

B. What is the name of the imalah used in the recitation of Ad Duri  from Kesai?

Jazakumullahu Khairan.  Wa Salamu aleikum wa rahmatulilahi wa barakatuh.

Answer:

Wa alaikum assalaam wa rahmatullahi wa barakatuh.

The reading of  has imaalah on the  or female  and the letter preceding when stopping on the word, except in the case of an alif preceding .  There is no imaalah on the   when stopping on a word if preceded by an alif.

 There are some letters or letter combinations though that have two allowable ways of reading the female  , one with imaalah, the other without.  These letters are those in the group of words: .

Also, if the letters in the word precede the female  have a or dhammah, then there are two allowed ways of reading them with the , with imaalah and without.  If the letters in the word , precede  and the letters are preceded by a kasrah or a saakinah, then they have compulsory imaalah along with the  when stopping on the word. 

In the words , ,   in surah Al-Ghaashiyah, the female  is preceded by the letter  which is one of the letters in the group of  .  Therefore there are two allowable ways of reading the  when stopping on it, with or without imaalah.  The reciter in this case read these words  the way that does not allow the imaalah in this letter combination.     

B.  reads with or grand imaalah, which is 50% alif and 50%   Warsh reads (other than one or two exceptions) with the minor imaalah, also called , which is 75% alif and only 25% .  Please also see:
