وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَأَبُو كُرَيْبٍ قَالَ يَحْيَى وَإِسْحَاقُ أَخْبَرَنَا وَقَالَ الآخَرَانِ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ تَزَوَّجَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم وَهْىَ بِنْتُ سِتٍّ وَبَنَى بِهَا وَهْىَ بِنْتُ تِسْعٍ وَمَاتَ عَنْهَا وَهْىَ بِنْتُ ثَمَانَ عَشْرَةَ ‏.‏
