Musnad Abu Ya'la al-Mawsili 109:264

Kamil narrated to us, Layth ibn Sa'd narrated to us, Abu al-Zubayr narrated to us, from Jabir, from the Messenger of Allah (may Allah bless him and grant him peace) that he said: "If one of you sees a vision that he dislikes, let him spit to his left three times, and let him seek refuge in Allah from the Shaytan three times, and let him turn from the side he was upon."
