حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، حَدَّثَنَا أَبُو عَامِرٍ الْعَقَدِيُّ، حَدَّثَنَا عَبَّادُ بْنُ رَاشِدٍ، حَدَّثَنَا الْحَسَنُ، قَالَ حَدَّثَنِي مَعْقِلُ بْنُ يَسَارٍ، قَالَ كَانَتْ لِي أُخْتٌ تُخْطَبُ إِلَىَّ. وَقَالَ إِبْرَاهِيمُ عَنْ يُونُسَ، عَنِ الْحَسَنِ، حَدَّثَنِي مَعْقِلُ بْنُ يَسَارٍ،. حَدَّثَنَا أَبُو مَعْمَرٍ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا يُونُسُ، عَنِ الْحَسَنِ، أَنَّ أُخْتَ، مَعْقِلِ بْنِ يَسَارٍ طَلَّقَهَا زَوْجُهَا، فَتَرَكَهَا حَتَّى انْقَضَتْ عِدَّتُهَا، فَخَطَبَهَا فَأَبَى مَعْقِلٌ، فَنَزَلَتْ Begin hadith 5.
