The Prophet ﷺ 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."
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا اسْتَيْقَظَ أُرَاهُ أَحَدُكُمْ مِنْ مَنَامِهِ فَتَوَضَّأَ فَلْيَسْتَنْثِرْ ثَلاَثًا فَإِنَّ الشَّيْطَانَ يَبِيتُ عَلَى خَيْشُومِهِ
