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