ʿAisha said, "Messenger of Allah ﷺ in his fatal illness, used to ask, 'Where will I be tomorrow? Where will I be tomorrow?", seeking ʿAisha's turn. His wives allowed him to stay wherever he wished. So he stayed at ʿAisha's house till he expired while he was with her." ʿAisha added, "The Prophet ﷺ expired on the day of my turn in my house and he was taken unto Allah while his head was against my chest and his saliva mixed with my saliva." ʿAisha added, "Abdur-Rahman bin Abu Bakr came in, carrying a Siwak he was cleaning his teeth with. Messenger of Allah ﷺ looked at it and I said to him, 'O ʿAbdurRahman! Give me this Siwak.' So he gave it to me and I cut it, chewed it (it's end) and gave it to Messenger of Allah ﷺ who cleaned his teeth with it while he was resting against my chest."
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَسْأَلُ فِي مَرَضِهِ الَّذِي مَاتَ فِيهِ يَقُولَ أَيْنَ أَنَا غَدًا أَيْنَ أَنَا غَدًا يُرِيدُ يَوْمَ عَائِشَةَ فَأَذِنَ لَهُ أَزْوَاجُهُ يَكُونُ حَيْثُ شَاءَ فَكَانَ فِي بَيْتِ عَائِشَةَ حَتَّى مَاتَ عِنْدَهَا قَالَتْ عَائِشَةُ فَمَاتَ فِي الْيَوْمِ الَّذِي كَانَ يَدُورُ عَلَىَّ فِيهِ فِي بَيْتِي فَقَبَضَهُ اللَّهُ وَإِنَّ رَأْسَهُ لَبَيْنَ نَحْرِي وَسَحْرِي وَخَالَطَ رِيقُهُ رِيقِي ثُمَّ قَالَتْ دَخَلَ عَبْدُ الرَّحْمَنِ بْنُ أَبِي بَكْرٍ وَمَعَهُ سِوَاكٌ يَسْتَنُّ بِهِ فَنَظَرَ إِلَيْهِ رَسُولُ اللَّهِ ﷺ فَقُلْتُ لَهُ أَعْطِنِي هَذَا السِّوَاكَ يَا عَبْدَ الرَّحْمَنِ فَأَعْطَانِيهِ فَقَضِمْتُهُ ثُمَّ مَضَغْتُهُ فَأَعْطَيْتُهُ رَسُولَ اللَّهِ ﷺ فَاسْتَنَّ بِهِ وَهْوَ مُسْتَنِدٌ إِلَى صَدْرِي
