Sense of contentment is what makes one truly wealthy or poor
TABARANI 1643:
from Abū Dhar —
The Messenger of Allah ﷺ asked, “O Abū Dharr, Do you think that having wealth is being wealthy?” He said, “Yes.” He ansked, “And do you think that not having wealth is poverty?” He said, “Yes.” He then said three things. The Messenger of Allah ﷺ said, “In fact, true wealth is in the heart and true poverty is in the heart: Whoever's richness is in his heart; will not be harmed no matter what happens to him in the world; Whoever is poor in his heart, he will not be satisfied no matter how much he has gained in the world. In fact he is only harmed by the greed of his own soul.”

قَالَ رَسُولُ اللهِ ﷺ «يَا أَبَا ذَرًّ تَقُولُ كَثْرَةُ الْمَالِ الْغِنَى؟» قُلْتُ نَعَمْ قَالَ «تَقُولُ قِلَّةُ الْمَالِ الْفَقْرُ؟» قُلْتُ نَعَمْ قَالَ ذَلِكَ ثَلَاثًا ثُمَّ قَالَ رَسُولُ اللهِ ﷺ «الْغِنَى فِي الْقَلْبِ وَالْفَقْرُ فِي الْقَلْبِ مَنْ كَانَ الْغِنَى فِي قَلْبِهِ لَا يَضُرُّهُ مَا لَقِيَ مِنَ الدُّنْيَا وَمَنْ كَانَ الْفَقْرُ فِي قَلْبِهِ فَلَا يُغْنِيهِ مَا أَكْثَرَ لَهُ فِي الدُّنْيَا وَإِنَّمَا يَضُرُّ نَفْسَهُ شُحُّها»
