In this nature...

In this nature, any nation will be miser, Which gets used to the act of pleasure-taking. In his letter to ‘Uthman b. Hunayf, Imam ‘Ali emphasizes this fact: "اَلا وَاِنَّ الشَجَرَةَ البَرِّيَةَ اَصلَبُ عُوداً وَالرَوائِعَ الخَضِرَةُ اَرَقُّ جُلُوداً وَالنَبَاتَاتُ البَدَويَّةُ اَقوَى وَقُوداً وَابطَأ خُمُودا" "Be aware that the trees of the desert have harder wood, and the green trees on the river have more delicate barks.
