Musnad Abu Ya'la al-Mawsili 152:155

And from Abdullah, he said: We were walking with the Messenger of Allah, may Allah bless him and grant him peace, and he passed by Ibn al-Sayyad. The Messenger of Allah, may Allah bless him and grant him peace, said: "I have hidden a secret for you." Ibn al-Sayyad said: "Al-Dukh (the smoke)." The Messenger of Allah, may Allah bless him and grant him peace, said: "Be driven away, for you will never exceed your limit."
