The Messenger of Allah (may Allah's peace and blessings be upon him) used to ask in his final illness: Where will I be tomorrow? Where will I be tomorrow? He was looking forward to ‘Ā'ishah's turn [to stay with her]. So, his wives allowed him to stay wherever he wished

عن عائشة رضي الله عنها أن رسول الله صلى الله عليه وسلم كان يَسْأَلُ في مرضه الذي مات فيه، يقول: «أيْن أنا غَدًا، أيْن أنا غَدًا» يُريد يوم عائشة، فأَذِنَ له أزواجه يكون حيث شاء، فكان في بيْت عائشة حتى مات عندها، قالت عائشة: فمات في اليوم الذي كان يدور عليَّ فيه، في بيتي، فَقَبَضَه الله وإنَّ رأسه لَبَيْنَ نَحْري وسَحْري، وخَالَطَ رِيقُه رِيقِي، ثم قالت: دخَل عبد الرحمن بن أبي بكر ومعَه سِواك يَسْتَنُّ به، فنظر إليه رسول الله صلى الله عليه وسلم ، فقلت له: أعْطِني هذا السواك يا عبد الرحمن، فَأَعْطَانِيه، فَقَضَمْتُه، ثم مَضَغْتُه، فأعْطَيته رسول الله صلى الله عليه وسلم فاسْتَنَّ به، وهو مُسْتَنِد إلى صدري.

‘Ā'ishah (may Allah be pleased with her) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) used to ask in his final illness: "Where will I be tomorrow? Where will I be tomorrow?" He was looking forward to ‘Ā'ishah's turn [to stay with her]. So, his wives allowed him to stay wherever he wished. He stayed at ‘Ā'ishah's house till he died there. ‘Ā'ishah added: "He died on the day of my turn in my house, and he was taken unto Allah while his head was between my chest and neck, and his saliva mixed with mine." ‘Ā'ishah then said: "‘Abdur-Rahmān ibn Abu Bakr came in carrying a tooth-stick that he was cleaning his teeth with. The Messenger of Allah (may Allah's peace and blessings be upon him) looked at it, so I said to him: 'O ‘Abdur-Rahmān, give me this tooth-stick.' He gave it to me and I cut it, chewed it (its end) and gave it to the Messenger of Allah (may Allah's peace and blessings be upon him) who cleaned his teeth with it while he was resting against my chest.”
