For example, this word 'raw-diatan', has 'round taa' as last letter, no matter if it has, fatha, kasra
or damma, if you stop on this, it have to read as 'raw-diah', 'Round Taa' have changed to 'Ha Sakin'. Remember, if you not stop on this, it
have to read 'Taa' as it is.
For more clarification listen below ayah.
While listening above audio, concentrate on English spelling colored as red and blue, reciter pronouncing red round 'Taa' as 'Taa' because he not stopping on that, but blue round 'Taa' pronouncing as 'Ha Sakin' because he stopping on that.
