Is there a proper way to make Dua? Do your hands have to be placed right next to each other, or can they be apart while making Dua? In qunoot I’ve seen people pray both ways (hands apart and hands together) and I was wondering if it mattered or effected the Dua at all

Your hands don’t have to be right next to each other. They can be apart. It’s recommend to put the hands right next to each other, without any gaps between the fingers.

In any case, both are allowed.
