Divination and Omens (Kitab Al-Kahanah Wa Al-Tatayyur)

Narrated Anas ibn Malik:

A man said: Messenger of Allah! we were in an abode in which our numbers and our goods were many and changed to an abode in which our numbers and our goods became few. The Messenger of Allah (ﷺ) said: Leave it, for it is reprehensible.
