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.”
‘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.
Ibn ‘Umar reported the Prophet as saying, “I had a dream in which I was using a tooth-stick, when two men, one older than the other, came to me. I handed the tooth-stick to the younger of the two and was told to respect the senior, so I handed it to the older.”
