As for food : that is so acidic that he cannot eat it, then it is a disease or pain that he cannot eat . Taking sour food from a person indicates hearing ugly words, and if he sees as if he is taking it and feeding him to someone else, then he hears that restaurant like him, and if he struck grief or sickness . And if he saw that he was patient with eating it and praise God Almighty for him, he would gain relief .
