عَنْ اَلْمِسْوَرِ بْنِ مَخْرَمَةَ رضى الله عنه
«أَنَّ سُبَيْعَةَ الْأَسْلَمِيَّةَ رَضِيَ اَللَّهُ عَنْهَا نُفِسَتْ بَعْدَ وَفَاةِ زَوْجِهَا بِلَيَالٍ، فَجَاءَتْ اَلنَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاسْتَأْذَنَتْهُ أَنْ تَنْكِحَ، فَأَذِنَ لَهَا، فَنَكَحَتْ». رَوَاهُ اَلْبُخَارِيُّ 11 صحيح
