Musnad Ahmad 3478
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn Juraij said: I heard ‘Ata’ say: I heard Ibn ‘Abbas (رضي الله عنه) say: The Prophet of Allah (ﷺ) said: "If the son of Adam had a valley filled with wealth he would like to have another one like it. Nothing could satisfy the soul of the son of Adam except dust. And Allah accepts the repentance of the one who repents.” Ibn 'Abbas said: I do not know whether this is from the Qur'an or not.
