أَخْبَرَنِي إِبْرَاهِيمُ بْنُ يَعْقُوبَ، قَالَ حَدَّثَنَا ابْنُ أَبِي مَرْيَمَ، قَالَ أَنْبَأَنَا سُفْيَانُ، قَالَ حَدَّثَنِي عَمْرُو بْنُ دِينَارٍ، عَنْ عَطَاءٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ تُوُفِّيَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَعِنْدَهُ تِسْعُ نِسْوَةٍ يُصِيبُهُنَّ إِلاَّ سَوْدَةَ فَإِنَّهَا وَهَبَتْ يَوْمَهَا وَلَيْلَتَهَا لِعَائِشَةَ ‏.‏
