Few morsels of food are enough : Hadith

Messenger of Allah (SAWS) said: "No man fills a container worse than his stomach. A few morsels that keep his back upright are sufficient for him. If he has to, then he should keep one-third for food, one-third for drink and one-third for his breathing.''
[At-Tirmidhi]

Commentary: This Hadith discourages us from overeating as this causes laziness and affects one's health.
