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 nightbird and which shrieks is the spirit of men. It is not the spirit of men. It is an animal.
Sunan Abi Dawud Book 30, Hadith 15
← Previous Hadith When the Messenger of Allah (ﷺ) heard a word, and he liked it, he said: We took your omen from your mouth.

Sunan Abi Dawud Book 30, Hadith 14 Next Hadith → When taking omens was mentioned in the presence of the Prophet (ﷺ), he said: The best type is the good omen, and it does not turn back a Muslim. If one of you sees anything he dislikes, he should say: O Allah, no one brings good things except Thee, and no one averts evil things except Thee and there is no might and power but in Allah.

Sunan Abi Dawud Book 30, Hadith 16
