Narrated Ibn ‘Abbas (Radi’Allahu anhu):
I heard the Prophet (Sall’Allahu alaihi wa sallam) saying,

“If the son of Adam (the human being) had two valleys of money, he would wish for a third, for nothing can fill the belly of Adam’s son except dust, and Allah forgives him who repents to Him.”

(Sahih Bukhari ~ Book #76, Hadith #444)
