It I. related from Abu Juhayfah who said: I heard Amir al-mu'minin, peace be upon him, saying: The first fighting with which you will be overpowered is the fighting with hands, thereafter with your tongues and then with your hearts. Consequently, he who does not recognize virtue with his heart or does not disapprove evil will be turned upside down. Thus, his upside will be turned downwards and his low side will be turned upwards.
