الكبرى للنسائي:٣٨١٢ – أَخْبَرَنَا عُبَيْدُ اللهِ بْنُ سَعِيدٍ قَالَ حَدَّثَنَا يَحْيَى يَعْنِي ابْنَ سَعِيدٍ الْقَطَّانُ عَنْ مَالِكٍ قَالَ أَخْبَرَنِي نَافِعٌ عَنْ نُبَيْهِ بْنِ وَهْبٍ عَنْ أَبَانَ بْنِ عُثْمَانَ عَنْ أَبِيهِ

عَنِ النَّبِيَّ ﷺ «نَهَى أَنْ يَنْكِحَ الْمُحْرِمُ أَوْ يُنْكِحَ أَوْ يَخْطُبَ»
