The prohibition of marriage for one who is in Ihram, and it is disliked for him to propose marriage
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 .
Ibn Abbas (Allah be pleased with them) reported that Allah's Messenger (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."
