Narrated Abu Huraira (Radhi-Allahu ‘anhu):
The Prophet (salAllahu alayhi wa sallam) said:
“Riches does not mean, having a great amount of property, but riches is self-contentment.”
[Sahih Bukhari – Book 76: Hadith 453]
Abu Huraira (Radhi-Allahu ‘anhu) reported:
that the Messenger of Allah (salAllahu alayhi wa sallam) had said:
Richness does not lie in the abundance of (worldly) goods but richness is the richness of the soul (heart, self).
[Sahih Muslim – Book 005: Hadith 2287]
