عن شداد بن أوس عن النبي صلى الله عليه وسلم قال: الكيس من دان نفسه وعمل لما بعد الموت والعاجز من أتبع نفسه هواها وتمنى على الله (سنن الترمذي الرقم: 2459)

Hazrat Shaddaad bin Aws (radhiyallahu ‘anhu) reports that Nabi (sallallahu ‘alaihi wasallam) said, “The prudent (and intelligent) person is the one who takes stock of his nafs and carries out righteous actions that will benefit him after his death, and the unwise (and foolish) person is the one who allows his nafs to follow its desires (and carries out actions against the commands of Allah Ta‘ala) while having hope upon Allah Ta‘ala (to forgive him).”
