It is narrated about Sayyiduna Ka'b bin Malik (may Allah be pleased with him) that when the time of his death drew near, Umm Mubashshir came to him and said: Convey my greetings of peace to my son. He said to her: Did you not hear the Messenger of Allah (peace and blessings be upon him) saying: "The soul of the believer is a bird that hangs in the tree of Paradise until it is raised on the Day of Resurrection"? She said: Of course, but I forgot.
