7. Ali ibn Muhammad ibn Bundar has narrated from Ibrahim ibn Ishaq al-Ahmar from ‘Abd Allah ibn Hammad from abu Bakr ibn abu Sammak who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘When you wake up during the night (for Salah (prayer)) you should brush your teeth; the angel comes and places his mouth over your mouth. Every word you say, he climbs with it to the heaven. Your mouth should have a pleasant smell.’”
