It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that I heard the Messenger of Allah (peace and blessings be upon him) say: "If the son of Adam had a valley full of wealth and riches, he would wish to have another like it, and nothing fills the belly of the son of Adam except dust. However, whoever repents, Allah turns to him in mercy." Sayyiduna Ibn Abbas (may Allah be pleased with them both) says: I do not know whether this is a part of the Qur'an or not.
