Narrated Abu Huraira (rad):

Allah’s Messenger (ﷺ) said: “When one of you wakes up from his sleep, he must blow of his nose three times, for the Satan spends the night inside one’s nostrils” [Agreed upon].

وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ إِذَا اِسْتَيْقَظَ أَحَدُكُمْ مِنْ مَنَامِهِ فَلْيَسْتَنْثِرْ ثَلَاثًا, فَإِنَّ اَلشَّيْطَانَ يَبِيتُ عَلَى خَيْشُومِهِ } مُتَّفَقٌ عَلَيْه ِ [1]‏ .‏
