True richness is contentment of the heart. The Prophet ﷺ said: “Richness is not in abundance of possessions; rather richness is the richness of the soul.” (al-Bukhārī). And: “Look to those below you, not to those above you — it is fitter that you not belittle Allah's favour upon you.” (al-Bukhārī & Muslim).
العربية: عن أبي هريرة رضي الله عنه عن النبيّ ﷺ قال: «ليس الغِنى عن كثرة العَرَض، ولكنّ الغِنى غِنى النفس». (البخاري).
Be content with Allah's provision — look at those with less; it fills the heart with gratitude.
