The professor of ethics in the seminary schools said: in the very ordinary story of eatables and non-eatables, the guidance of the divine prophets is so correct and perfect; The divine prophets have asked us to avoid eating what is harmful to body, mind, spirit, and morals. For example, a few days ago, the national news announced that in one of the cities of Iran, some people lost their lives due to drinking alcoholic beverages and the others are in bad health condition, the divine prophets asked us not to drink from this substance in the past. The people should sit back and reflect upon the reason for its being unlawful, and then they will understand that it's harmful to the body. And the reason for some lawful things (Halal) is to benefit people. the unlawful things are harmful to people whether for his mind or body or for his ethic or the society or his family. The lawful things are beneficial for all aspects of one's life. When the lawful things and the unlawful things are mixed, the situations of the body, thinking, the family and the society will disintegrate.
