باب لاَ يَجُوزُ نِكَاحُ الْمُكْرَهِ
Sahih al-Bukhari 6945

Narrated Khansa' bint Khidam Al-Ansariya:

That her father gave her in marriage when she was a matron and she disliked that marriage. So she came and (complained) to the Prophets and he declared that marriage invalid. (See Hadith No. 69, Vol. 7)

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 وسلم فَرَدَّ نِكَاحَهَا‏.‏
