Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated: The Messenger of Allah (peace and blessings be upon him) used to say this often, so I do not know whether it was something he considered preferable or if it is from the Book of Allah: "If a person has two valleys full of wealth, he will wish for a third like them; nothing will fill his soul except (the grave's) dust. Whoever repents, Allah accepts his repentance."
