Sayyiduna Ibn Umar (may Allah be pleased with them both) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "The poor of my Ummah will enter Paradise forty years before its rich." I said: Describe them to us. He (peace and blessings be upon him) said: "They are those whose clothes are soiled and whose hair is dishevelled, who are not given permission at doors, and who are not able to marry wealthy women; the easts and wests of the earth will be entrusted to them; they give all that is due from them, but they are not given all that is due to them."
