5. Maintaining the 1/3rd rule in eating
Miqdam bin Madikarib said: “I heard the Messenger of Allah ṣallallāhu 'alayhi wa sallam (peace and blessings of Allāh be upon him) say:
‘A human being fills no worse vessel than his stomach. It is sufficient for a human being to eat a few mouthfuls to keep his spine straight. But if he must (fill it), then one-third of food, one third for drink and one third for air.’” [Ibn Majah]
It is an underestimated fact that food has a dramatic effect on your body’s and brain’s performance.
This hadith clearly highlights that overeating is a reprehensible quality we should stay away from.
However, it is also important to remember that undereating is equally harmful to a person.
In order to function, we need to have a balanced outlook towards our meals; our level of food consumption should not leave us feeling tired or bloated.
This is a state that leads to laziness, which is a vice we seek refuge in Allah subḥānahu wa ta'āla (glorified and exalted be He) from.
Can you conquer the world by sleeping? No. So, eat a nutritious, balanced meal that is sufficient in suppressing your hunger.
