The Messenger of Allah (ﷺ) said: “There is no hamah [refers to a Jahili Arab tradition described variously as: a worm which infests the grave of a murder victim until he is avenged, an owl; or the bones of a dead person turned into a bird that could fly), no "adwa [contagion, transmission of infectious disease without the permission of Allah] and no tiyarah [superstitious belief in bird omens]. If there were any (omen), it would be in a woman, a horse or a house."
