١۔ كتاب الطهارة
"When any one of you wakes from sleep to perform Wudu', then let him sniff water in his nose and blow it out three times, for the Shaitan spends the night on his nose."
عَنْ رَسُولِ اللَّهِ ﷺ قَالَ إِذَا اسْتَيْقَظَ أَحَدُكُمْ مِنْ مَنَامِهِ فَتَوَضَّأَ فَلْيَسْتَنْثِرْ ثَلاَثَ مَرَّاتٍ فَإِنَّ الشَّيْطَانَ يَبِيتُ عَلَى خَيْشُومِهِ
