Every night when he prophet (May peace be upon him) went to his bed, he joined his hands and breathed into them, reciting into them:”say: he is Allah, One” and say ; I seek refuge in the Lord of the dawn and Say: I seek refuge in the Lord of men. Then he would wipe as much of his body as he could with his hands, beginning with his head, his face and the front of his body, doing that three times. (Using translation from Abū Dāʾūd 5056)  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا أَوَى إِلَى فِرَاشِهِ كُلَّ لَيْلَةٍ «جَمَعَ كَفَّيْهِ ثُمَّ نَفَثَ فِيهِمَا فَقَرَأَ فِيهِمَا قُلْ هُوَ اللهُ أَحَدٌ وَقُلْ أَعُوذُ بِرَبِّ الْفَلَقِ وَقُلْ أَعُوذُ بِرَبِّ النَّاسِ ثُمَّ يَمْسَحُ بِهِمَا مَا اسْتَطَاعَ مِنْ جَسَدِهِ يَبْدَأُ بِهِمَا عَلَى رَأْسِهِ وَوَجْهِهِ وَمَا أَقْبَلَ مِنْ جَسَدِهِ يَفْعَلُ ذَلِكَ ثَلَاثَ مَرَّاتٍ»
