Ever heard of the cause of the first disobedience in the heavens? ENVY! That was it! Ibleess (Shaytaan) disobeyed Allah, his Lord, out of envy, arrogance, and pride. (See Al-Araaf [7]: 12). Envy is also one of the commonest sins on earth! It is the deadly disease of the heart that destroys personal as well as communal relationships! ENVY: its causes, its effects and how to deal with it, is the subject of this small but beneficial book. May the one who is afflicted with this disease fine cure in the prescription contained in this book. (Ameen)
