"Every Son of Adam is a Sinner, and the Best of Sinners are those who Repent" [Tirmidhi]

Abdullah bin Abbas said: “You who commit a sin, do not feel secure about the results, for what goes along with the sin is more serious than the sin itself. Your lack of shame before the angels, who witness you when you commit the sin, is more serious than the sin itself. Your laughter when you sin, as you forget the punishment of Allah is more serious than the sin itself. Your delight if you get a chance to sin, is more serious than the sin itself. Even your disappointment, if you miss a chance to sin is more serious than the sin itself.”
