If ‘Real Lengthening’ comes at stopping,  vowel sound will be prolonged for one alif as usual

قَالُوْا O

سَخَّرَهَا O

رَسُوْلَا O

اٰمَنُوْا O

نُوْحِيْهَا O

 

 

 

 

 

 

But if vertical Fatha, vertical Kasrah or inverse Dammah comes at ه  at the time of stopping then we will read it with a sakin  (will not prolong the voice). 

غَيْبِهٖ O

رُسُلُه O

اَهْلُه O

رَبِّهٖ O

مٰلَه O
