Hawzah News Agency - The commander of the faithful peace be upon him says:
أَزْرَى بِنَفْسِهِ مَنِ اسْتَشْعَرَ الطَّمَعَ
He who adopts greed as a habit devalues himself;
وَ رَضِيَ بِالذُّلِّ مَنْ كَشَفَ عَنْ ضُرِّهِ
he who discloses his hardship agrees to humiliation;
وَ هَانَتْ عَلَيْهِ نَفْسُهُ مَنْ أَمَّرَ عَلَيْهَا لِسَانَهُ
and he who allows his tongue to overpower his soul debases the soul.
