Greed is poverty and resignation is wealth
عن عمر بن الخطاب رضي الله عنه انه قال الطمع فقر واليأس غنى وان احدكم اذا يئس من شيء استغنى عنه
It is reported that ‘Umar Ibn Khattab (رضي الله عنه) said:
Greed is poverty and resignation is wealth. When any one of you gives up hope of something, he becomes independant of it.
[Al ‘Uboodiyah by Ibn Taymiyyah]
