Ayesha reported,

The Messenger of Allah ﷺ, during the illness in which he died, kept asking, "Where will I be tomorrow? Where will I be tomorrow?" He meant Ayesha's day. So his wives gave him permission to stay wherever he wished, and he remained in Ayesha's house until he died there.Ayesha said, "He died on the day when it was my turn, in my house. Allah took him while his head was resting between my neck and my chest, and his saliva mingled with mine."Then she said, "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, and I bit off the end, then chewed it to soften it, and gave it to the Messenger of Allah ﷺ. He cleaned his teeth with it while leaning against my chest."

عن عائشة

أن رسول الله ﷺ كان يسأل في مرضه الذي مات فيه يقول: أين أنا غدا؟ أين أنا غدا؟ يريد يوم عائشة، فأذن له أزواجه يكون حيث شاء، فكان في بيت عائشة حتى مات عندها. قالت عائشة: فمات في اليوم الذي كان يدور علي فيه في بيتي، فقبضه الله وإن رأسه لبين نحري وسحري، وخالط ريقه ريقي، ثم قالت: دخل عبد الرحمن بن أبي بكر ومعه سواك يستن به، فنظر إليه رسول الله ﷺ فقلت له: أعطني هذا السواك يا عبد الرحمن، فأعطانيه فقضمته، ثم مضغته، فأعطيته رسول الله ﷺ، فاستن به وهو مستند إلى صدري.
