I wanted to know that our dear one passed away a year ago and my mom brought his graves sands becauses we are going to holy shrines here and my mom told that his wish was to visit that shines but he couldn’t so I want to know that it is Jaez to get that graves sand and take to the shrines?

There is no harm in doing that as long as you get permission to put this sand inside the Holy shrine. But if you just want to put in one of the graveyard of that city then its ok.
