Divination and Omens (Kitab Al-Kahanah Wa Al-Tatayyur)
Dawud :: Book 29 : Hadith 3909
Narrated Urwah ibn Amir al-Qurashi:
When taking omens was mentioned in the presence of the Prophet (peace_be_upon_him), 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.
