Answer
Wa alaikum assalaam wa rahmatullahi wa barakatuh,
To see the lesson on   , please click on this link: http://www.abouttajweed.com/stopping-on-the-ends-of-words/stopping-on-the-ends-of-words-1.html  You will need to scroll down on the page. 

After reading the lesson, you will note that we can stop with (giving 1/3 of the vowel on the kasrah or dhammah of the last letter on the word when stopping) on any word ending with a conjugated or fixed dhammah or kasrah.  We cannot stop with on a word that ends with a transitional dhammah or kasrah.  This is explained in the lesson at the link above, so we will not go into details here.  
Wa iyyaaakum.
