Does a hamza with has a harakah on it, fatha kasra or dhummah, followed by another letter be given the same timing as any other voweled letter gets?

Question
Assalaamu-alaikum.

Does a hamza with has a harakah on it, fatha kasra or dhummah, followed by another letter be given the same timing as any other voweled letter gets?

examples would be: wal ard. Now is the fatha of ard given the same timing as any other letter which has a fatha which is 1 one vowel count?

example 2: iqra. Is the kasra on the word iqra given the same timing as any other letter which has kasra which is 1 one vowel count?

Do hamzas which are mutaharrik, have the same vowel count or timing as any other letter which are mutaharrik? What about when hamza is saakin preceeded by a mutaharrik letter such as the last ayah of surah feel: ma'kool. Does the vowel count of the previous letter (ma') become shorter than 1 vowel count?

Sometimes it seems to me it becomes slightly shorter than one vowel count, but I am not sure if this is the correct way.

Jazakallahu Khairan for answering all my previous questions, it really does help a lot.

Answer
Wa alaikum assalam wa rahmatullahi wa barakaaatuh
All hamzaat (plural of hamzah) which have a vowel are given one vowel count and should be equal to each other.  So the vowel on the hamzah in the  word equals the vowel on the word and equals the timing on the vowel of the hamzah on the word .. 

Yes, all letters with a vowel have the same time as others with a vowel -this doesn’t refer to the shaddah because then there are two letters, but the voweled part of the shaddah is the same as all other voweled letters.

The vowel count of a letter does not decrease or increase due to the hamzah after it.  The hamzah has the characteristic of shiddah- or imprisonment of the running of the sound, and this shows prominently when there is a sukoon on the hamzah, which will have a short amount of time, less than the letters which have rikhaawah or tawassit. 

Wa iyyaaakum.
