SHAFAQNA – It is narrated from Imam Hassan (AS) who said: People’s lives are ruined by three things; arrogance, greed and jealousy. Arrogance destroys the religion, and for the sake of it, Iblis was cursed (by Allah (SWT)). Greed which is an enemy to the human being, and for the sake of it, Adam (AS) was expelled from paradise. Jealousy is the source of badness, and for the sake of it, Cain killed Able .
