‘A'isha said that God’s messenger was using the tooth-stick when two men, one older than the other, were with him. A revelation came to him about the excellence of the tooth-stick in which he was told to show proper respect, and give it to the older of the two.
She reported God’s messenger as saying, “The prayer before which the tooth-stick is used is seventy times more excellent than that before which it is not used.”
Abu Umama reported God’s messenger as saying, “Gabriel never came to me without ordering me to use the tooth-stick, with the result that I have been afraid of chafing the front of my mouth.”
