حَدَّثَنَا عَفَّانُ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا أَيُّوبُ بْنُ مُوسَى، عَنْ نُبَيْهِ بْنِ وَهْبٍ، أَنَّ عُمَرَ بْنَ عُبَيْدِ اللَّهِ، أَرَادَ أَنْ يُزَوِّجَ، ابْنَهُ وَهُوَ مُحْرِمٌ فَنَهَاهُ أَبَانُ وَزَعَمَ أَنَّ عُثْمَانَ، رَضِيَ اللَّهُ عَنْهُ حَدَّثَ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْمُحْرِمُ لَا يَنْكِحُ وَلَا يُنْكِحُ.
