 An exception to this is when stopping on a word with the last letter a female , called in Arabic, such as in the word in this case there is no medd, instead with stop with a saakinah. 
If there is a  qalqalah letter and it has a tanween with a fathah, then we substitute an alif for the tanween fathah, so the qalqalah letter is read with a fathah, followed by an alif.  Therefore, there is no qalqalah in this case because the qalqalah letter is not saakin, instead it has a vowel.
