It is narrated from Sayyiduna Ibn Amr (may Allah be pleased with him) that a man came to the service of the Noble Prophet (peace and blessings be upon him) to pledge allegiance and said, "I have come to pledge allegiance to you for migration, and (I have made a great sacrifice that) I have left my parents weeping." The Noble Prophet (peace and blessings be upon him) said: "Go back and make them laugh just as you made them weep." And he refused to accept his pledge of allegiance.
