Riyad us Saliheen: Hadith 1669

I heard the Messenger of Allah (ﷺ) saying, "The practice of 'Iyafah, the interpretation of omens from the flight of birds, the practice of divination by drawing lines on the ground and taking evil omens are all practices of Al-Jibt (the idol, the diviner, or sorcerer)."

[Abu Dawud].
