Musnad Ahmad 26:279

Abu al-Jawwab narrated to us, Ammar ibn Ruzayq narrated to us, from Ata’ ibn al-Sa’ib, from Abu Abd al-Rahman, from Abdullah ibn Mas’ud, from the Prophet, peace and blessings of Allah be upon him, that he used to seek refuge from the devil, from his *hamz* (stifling/madness), his *nafth* (spitting/incantations), and his *nafkh* (blowing/pride). He said: "His *hamz* is the *mawta* (epilepsy/fainting), his *nafth* is poetry, and his *nafkh* is pride."
