باب تَحْرِيمِ نِكَاحِ الْمُحْرِمِ وَكَرَاهَةِ خِطْبَتِهِ ‏‏
Sahih Muslim 1410 a

Ibn Abbas (Allah be pleased with them) reported that Allah's Apostle (ﷺ) married Maimuna in the state of Ihram. Ibn Numair made this addition:

" I narrated it to Zuhri and he said: Yazid b. al-Asamm (Allah be pleased with him) told me that he (the Holy Prophet) married her when he was not a muhrim."
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، نُمَيْرٍ وَإِسْحَاقُ الْحَنْظَلِيُّ جَمِيعًا عَنِ ابْنِ عُيَيْنَةَ، - قَالَ ابْنُ نُمَيْرٍ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، - عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ أَبِي الشَّعْثَاءِ، أَنَّ ابْنَ، عَبَّاسٍ أَخْبَرَهُ أَنَّ النَّبِيَّ صلى الله عليه وسلم تَزَوَّجَ مَيْمُونَةَ وَهُوَ مُحْرِمٌ ‏.‏ زَادَ ابْنُ نُمَيْرٍ فَحَدَّثْتُ بِهِ الزُّهْرِيَّ فَقَالَ أَخْبَرَنِي يَزِيدُ بْنُ الأَصَمِّ أَنَّهُ نَكَحَهَا وَهُوَ حَلاَلٌ ‏.‏
