Amir al-mu'minin, peace be upon him, said: He who adopts greed as a habit devalues himself; he who discloses his hardship agrees to humiliation; and he who allows his tongue to overpower his soul debases the soul.
وَ قَالَ (عليهالسلام ): أَزْرَى بِنَفْسِهِ مَنِ اسْتَشْعَرَ الطَّمَعَ وَ رَضِيَ بِالذُّلِّ مَنْ كَشَفَ عَنْ ضُرِّهِ وَ هَانَتْ عَلَيْهِ نَفْسُهُ مَنْ أَمَّرَ عَلَيْهَا لِسَانَهُ.
