ʿAbdur-Rahman bin Abu Bakr entered upon the Prophet ﷺ while I was supporting the Prophet ﷺ on my chest. ʿAbdurRahman had a fresh Siwak then and he was cleaning his teeth with it. Messenger of Allah ﷺ looked at it, so I took the Siwak, cut it (chewed it with my teeth), shook it and made it soft (with water), and then gave it to the Prophet ﷺ who cleaned his teeth with it. I had never seen Messenger of Allah ﷺ cleaning his teeth in a better way. After finishing the brushing of his teeth, he lifted his hand or his finger and said thrice, "O Allah! Let me be with the highest companions," and then died. ʿAisha used to say, "He died while his head was resting between my chest and chin."  

عَنْ عَائِشَةَ دَخَلَ عَبْدُ الرَّحْمَنِ بْنُ أَبِي بَكْرٍ عَلَى النَّبِيِّ ﷺ وَأَنَا مُسْنِدَتُهُ إِلَى صَدْرِي وَمَعَ عَبْدِ الرَّحْمَنِ سِوَاكٌ رَطْبٌ يَسْتَنُّ بِهِ فَأَبَدَّهُ رَسُولُ اللَّهِ ﷺ بَصَرَهُ فَأَخَذْتُ السِّوَاكَ فَقَصَمْتُهُ وَنَفَضْتُهُ وَطَيَّبْتُهُ ثُمَّ دَفَعْتُهُ إِلَى النَّبِيِّ ﷺ فَاسْتَنَّ بِهِ فَمَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ اسْتَنَّ اسْتِنَانًا قَطُّ أَحْسَنَ مِنْهُ فَمَا عَدَا أَنْ فَرَغَ رَسُولُ اللَّهِ ﷺ رَفَعَ يَدَهُ أَوْ إِصْبَعَهُ ثُمَّ قَالَ فِي الرَّفِيقِ الأَعْلَى ثَلاَثًا ثُمَّ قَضَى وَكَانَتْ تَقُولُ مَاتَ بَيْنَ حَاقِنَتِي وَذَاقِنَتِي
