Arabic hadith text
حَدَّثَنَا يَحْيَى بْنُ قَزَعَةَ، حَدَّثَنَا مَالِكٌ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَبْدِ الرَّحْمَنِ، وَمُجَمِّعٍ، ابْنَىْ يَزِيدَ بْنِ جَارِيَةَ الأَنْصَارِيِّ عَنْ خَنْسَاءَ بِنْتِ خِذَامٍ الأَنْصَارِيَّةِ، أَنَّ أَبَاهَا، زَوَّجَهَا وَهْىَ ثَيِّبٌ، فَكَرِهَتْ ذَلِكَ، فَأَتَتِ النَّبِيَّ صلى الله عليه وسلمفَرَدَّ نِكَاحَهَا.
