It is narrated from Hazrat Anas (may Allah be pleased with him) that he heard the Prophet (peace and blessings be upon him) saying—I do not know whether it was a verse of the Qur'an or a saying of the Prophet (peace and blessings be upon him)—that if the son of Adam had two valleys full of wealth, he would desire a third, and nothing fills the belly of the son of Adam except the dust of the grave, and Allah accepts the repentance of whoever repents.
