Abdul-Rahman bin Abu Bakr came in carrying a siwak which he was using to clean his teeth. The Messenger of Allah ﷺ looked at it, so I said to him, "Give me that siwak, Abdul-Rahman." He handed it to me, and I broke off the tip, then chewed it to soften it, and gave it to the Messenger of Allah ﷺ. He used it to clean his teeth while resting against my chest.
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 مستند إلى صدري.
