حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنِ ابْنِ عَوْنٍ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، قَالَ: ذَكَرُوا عِنْدَ عَائِشَةَ أَنَّ عَلِيًّا كَانَ وَصِيًّا ‏.‏ فَقَالَتْ:مَتَى أَوْصَى إِلَيْهِ؟ فَلَقَدْ كُنْتُ مُسْنِدَتَهُ إِلَى صَدْرِي - أَوْ إِلَى حِجْرِي فَدَعَا بِطَسْتٍ فَلَقَدِ انْخَنَثَ فِي حِجْرِي فَمَاتَ وَمَا شَعَرْتُ بِهِ. فَمَتَى أَوْصَى ـ صلى الله عليه وسلم ـ؟ ‏
