Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) said: "If the son of Adam had two valleys of wealth, he would wish for a third, and nothing fills the belly of the son of Adam except dust, and Allah accepts the repentance of whoever repents."
