I want to ask question abouth eating. My first problem with eating is that I’m eating fast. Second problem is that I eat to much. I read on forums that Prophet Muhamed s. a. w. s. said: If you must eat make sure you fill one third of your stomach with food, one third with water and leave one third for air i.e. leave it empty. My question is how to measure that <one third>. How much is one third.
