(عن ابن عمر قال : تجشأ رجل عند النبي صلى الله عليه و سلم فقال كف عنا جشاءك فإن أكثرهم شبعا في الدنيا أطولهم جوعا يوم القيامة (سنن الترمذى

Hadrat Ibn Umar R.A says that Rasulullah Salallahu Alaihi Wasallam heard a person belch and said, “Shorten your belch (in other words don’t belch) because the most hungry person on the day of Qiyaamah will be the one who was most satiated in the world.

The name of this person (who had belched) was Wahab ibn Abdullah. He hadn’t reached the age of puberty at that time. After listening to the advice of Rasulullah Salallahu Alaihi Wasallam he never ate to his fill again until he departed from the world. If had eaten in the morning, he wouldn’t eat in the evening and if he had eaten in the evening he wouldn’t eat in the morning.
