Traditional storytelling among Palestinians is prefaced with an invitation to the listeners to give blessings to God and the Prophet Mohammed or the Virgin Mary as the case may be, and includes the traditional opening: "There was, or there was not, in the oldness of time..." Formulaic elements of the stories share much in common with the wider Arab world, though the rhyming scheme is distinct. There are a cast of supernatural characters: djinns who can cross the Seven Seas in an instant, giants, and ghouls with eyes of ember and teeth of brass. Stories invariably have a happy ending, and the storyteller will usually finish off with a rhyme like: "The bird has taken flight, God bless you tonight," or "Tutu, tutu, finished is my "haduttu" (story)."
