حَدَّثَنِي عُبَيْدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، قَالَ تُوُفِّيَتْ خَدِيجَةُ قَبْلَ مَخْرَجِ النَّبِيِّ صلى الله عليه وسلم إِلَى الْمَدِينَةِ بِثَلاَثِ سِنِينَ، فَلَبِثَ سَنَتَيْنِ أَوْ قَرِيبًا مِنْ ذَلِكَ، وَنَكَحَ عَائِشَةَ وَهْىَ بِنْتُ سِتِّ سِنِينَ، ثُمَّ بَنَى بِهَا وَهْىَ بِنْتُ تِسْعِ سِنِينَ‏.‏
