Hawzah News Agency – Imam al-Kazim (AS) said to Hashim, exhorting him,

إيّاكَ والطَّمَعَ، وعلَيكَ باليَأسِ مِمّا في أيدِي الناسِ، وأمِتِ الطَّمَعَ مِن المَخلوقِينَ؛ فإنَّ الطَّمَعَ مِفتاحٌ لِلذُّلِّ، واختِلاسُ العَقلِ، واختِلاقُ المُرُوّاتِ، وتَدنِيسُ العِرضِ، والذَّهابُ بِالعِلمِ.

‘You must beware of greed, and despair of acquiring anything in the possession of others. Suppress the greed in others for verily greed is the key to disgrace, it exploits the intellect, fabricates valorous qualities for itself, tarnishes one’s reputation, and does away with one’s knowledge.’
