Sayyida Aisha Siddiqa (may Allah be pleased with her) narrates: When the Prophet Muhammad (peace and blessings be upon him) would go to sleep, he would bring both his hands together, blow on them, then recite Surah Ikhlas, Surah Falaq, and Surah Nas. Then he would wipe both hands over his face, his head, and his entire body. Aqil narrates: I have also seen Ibn Shihab Zuhri doing this.
