Abu Dawud
Divination and Omens
Book Number: 023 / Hadith Number: 3908
Narated By N/A : 'Ata' said: People said: safar is a pain within the belly. I asked: What is hamah? He said: People said (believed) that hamah which is an owl or a flight bird and which shrieks is the spirit of men. It is not the spirit of men. It is an animal.
