One such bizarre teaching is Muhammads assertion that Satan literally stays in a persons upper nose at night and needs to be flushed out by snorting water in and out of ones nose three times! Abu Huraira reported: The Apostle of Allah said. When any one of you awakes up from sleep and performs ablution, he must clean his nose three times, for the devil spends the night in the interior of his nose. (Sahih Muslim, Book 002, Number 0462) And: Narrated Abu Huraira: The Prophet said, If anyone of you rouses from sleep and performs the ablution, he should wash his nose by putting water in it and then blowing it out thrice, because Satan has stayed in the upper part of his nose all the night. (Sahih al-Bukhari, Volume 4, Book 54, Number 516) The footnote to this particular hadith states: (1) (H. 3295) We should believe that Satan actually stays in the upper part of ones 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 Messenger.
