Abu Dawud
Divination and Omens
Book Number: 023 / Hadith Number: 3909
Narated By Urwah ibn Amir al-Qurashi : When taking omens was mentioned in the presence of the Prophet (pbuh), 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.
