حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ فَارِسٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ أُمِّ حَبِيبَةَ، أَنَّهَا كَانَتْ عِنْدَ ابْنِ جَحْشٍ فَهَلَكَ عَنْهَا - وَكَانَ فِيمَنْ هَاجَرَ إِلَى أَرْضِ الْحَبَشَةِ - فَزَوَّجَهَا النَّجَاشِيُّ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهِيَ عِنْدَهُمْ .
