Wa alaikum assalaam wa rahmatu Allahi wa barakuatuh.

Wa iyyaakum wa-l-muslimeen.  Jazaka Allahu khairan, and may Allah accept the fast of Ramadhan and our righteous deeds.

The letter  is saakinah and has tafkheem as well as  and , so care has to be taken that the  is pronounced from the correct articulation point and the tip of the tongue is not used, and the characteristics of the  all should be given their rights, including the longest timing of a saakin letter for the characteristic of .  After this the letter , needs to be pronounced carefully from the top of tip of the tongue, but special care needs to be taken that the characteristics of the letter  that are not present in the letter  do not carry over.  So all tafkheem should be gone, since has tarqeeq, not tafkheem.  Most likely this is the difficulty you are encountering, the articulation point of the  is unique, and it has some strong characteristics that are especially apparent when saakinah, and afterwards the  has tarqeeq and other weak characteristics. 

Wa assalaam alaikum.
