It is narrated from Hazrat Aisha that when the Prophet (peace be upon him) would come to his bed every night, he would bring his palms together and recite Surah Ikhlas and the two Mu'awwidhatayn over them, then blow into them, and wipe his hands over his body as far as possible, starting with his head, face, and the front of his body, and he would do this three times.
