I read somewhere that you shouldn't let your hands hanging while you're doing the prayer, you should put them around your chest or your stomach like in this picture:
Some even say only one of the position of the hands is right, before reading the article I didn't know it was important where you put your hands during the prayer. Can anyone tell me which one is right and why?
