Yahya related to me from Malik from Zayd ibn Aslam from Ata ibnYasar that the Messenger of Allah, may Allah bless him and grant himpeace, said, "All that will be left of prophecy after me are themubashshirat." They said, "What are the mubashshirat, Messenger ofAllah?" He said, "The true dream which a man who is salih sees - orwhich is shown to him - is a forty-sixth part of prophecy."
