Mukhtasar Bukhari (Abridged) 1385 — Description of Iblis and his army

Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Satan comes to one of you and says (i.e., puts a whisper), 'Who created this?' and 'Who created that?' until he says, 'Tell me, who created your Lord?' So when it comes to this point, that person should recite 'A'udhu billah' (I seek refuge with Allah) and abandon such satanic thoughts."
