Answer
Wa alaikum assalaam wa rahmatullahi wa barakaatuh
The general rule in Arabic is that we stop with a sukoon on the last letter.  In this case, it is a  , but not a medd letter, so it is as any other letter and we put a temporary sukoon on the when stopping. This requires some care because the daal before it is saakinah.  We have to make sure we give the qalqalah to the daal without adding a vowel and then pronounce the with circling our two lips and take care that we do not lengthen it.
