Sayyidah Ayshah (RA) narrated: When the Prophet (SAW) came to his bed every night, he wouid place together both palms (in a scoop), blow on them and recite on them:
“Surah al-Ikhlas, al-Falaq and an-Naas”. Then he would wipe them on as much of his body as he could, beginning them at his head and his face and that of his body that is in the front. He would do that three times.
[Bukhari 6319, Abu Dawud 5056, Ibn e Majah 3875]
