Sahih (Sahih al-Bukhari)
حَدَّثَنَا يَحْيَى بْنُ قَزَعَةَ، حَدَّثَنَا مَالِكٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنِ الْمِسْوَرِ بْنِ مَخْرَمَةَ، أَنَّ سُبَيْعَةَ الأَسْلَمِيَّةَ، نُفِسَتْ بَعْدَ وَفَاةِ زَوْجِهَا، بِلَيَالٍ فَجَاءَتِ النَّبِيَّ صلى الله عليه وسلم فَاسْتَأْذَنَتْهُ أَنْ تَنْكِحَ، فَأَذِنَ لَهَا، فَنَكَحَتْ.
