Sahih al-Bukhari 3100

Arabic

حَدَّثَنَا ابْنُ أَبِي مَرْيَمَ، حَدَّثَنَا نَافِعٌ، سَمِعْتُ ابْنَ أَبِي مُلَيْكَةَ، قَالَ قَالَتْ عَائِشَةُ ـ رضى الله عنها تُوُفِّيَ النَّبِيُّ صلى الله عليه وسلم فِي بَيْتِي، وَفِي نَوْبَتِي، وَبَيْنَ سَحْرِي وَنَحْرِي، وَجَمَعَ اللَّهُ بَيْنَ رِيقِي وَرِيقِهِ‏.‏ قَالَتْ دَخَلَ عَبْدُ الرَّحْمَنِ بِسِوَاكٍ، فَضَعُفَ النَّبِيُّ صلى الله عليه وسلم عَنْهُ، فَأَخَذْتُهُ فَمَضَغْتُهُ ثُمَّ سَنَنْتُهُ بِهِ‏.‏
