Abdul-Rahman bin Abu Bakr came in carrying a tooth-stick which he was using to clean his teeth. The Messenger of Allah ﷺ looked at it, so I said to him, "Give me that tooth-stick, Abdul-Rahman."He handed it to me. I broke off the tip, chewed on it to soften it, and then gave it to the Messenger of Allah ﷺ. He cleaned his teeth with it while leaning back against my chest.
حدثنا إسماعيل قال حدثني سليمان بن بلال قال قال هشام بن عروة أخبرني أبي
دخل عبد الرحمن بن أبي بكر ومعه سواك يستن به فنظر إليه رسول الله ﷺ فقلت له أعطني هذا السواك يا عبد الرحمن فأعطانيه فقصمته ثم مضغته فأعطيته رسول الله ﷺ فاستن به وهو مستسند إلى صدري
