Bukhari vol IV, no. 516: “Satan stays in the upper part of the nose all night.”
Footnote (1): We should believe that Satan actually stays in the upper part of one’s nose, though we cannot perceive how, for this is related to the unseen world of which we know nothing except what Allah tells us through his Apostle Mohammed.
Muslim vol I, no. 462: Abu Huraira reported: The Apostle of Allah said, “When any one of you awakes from sleep and performs ablution, he must clean his nose three times, for the devil spends the night in the interior of his nose.”
