Ash-Shama'il Al-Muhammadiyah, Book 38, Hadith 244 (English) ⓘ
'Aayeshah Radiyallahu 'Anha narrates: "Every night before Rasulullah Sallallahu 'Alayhi Wasallam slept on his bed, he put together his hands (as in the du'aa) and blew on it and recited (the surahs of) AI-Ikhlaas (Qul huwauahu ahad), AI-Falaq (Qul a'udhu birabbil falaq), and An-Naas (Qui a'udhu birabbin naas) and wiped those parts of the body that he could (wherever the hand could reach). He began with the head, then the face and then the front part of his body. This was done thrice".
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ: حَدَّثَنَا الْمُفَضَّلُ بْنُ فَضَالَةَ، عَنْ عُقَيْلٍ، أُرَاهُ عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ: كَانَ رَسُولُ اللهِ صلى الله عليه وسلم، إِذَا أَوَى إِلَى فِرَاشِهِ كُلَّ لَيْلَةٍ جَمَعَ كَفَّيْهِ فَنَفَثَ فِيهِمَا، وَقَرَأَ فِيهِمَا: قُلْ هُوَ اللَّهُ أَحَدٌ وَ قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ وَ قُلْ أَعُوذُ بِرَبِّ النَّاسِ، ثُمَّ مَسَحَ بِهِمَا مَا اسْتَطَاعَ مِنْ جَسَدِهِ، يَبْدَأُ بِهِمَا رَأْسَهُ وَوَجْهَهُ وَمَا أَقْبَلَ مِنْ جَسَدِهِ، يَصْنَعُ ذَلِكَ ثَلاثَ مَرَّاتٍ.
