I heard 'Uthman b. 'Affan say that Messenger of Allah ﷺ had stated: A Muhrim must neither marry himself, nor arrange the marriage of another one, nor should he make the proposal of marriage.  

عَنْ نُبَيْهِ بْنِ وَهْبٍ أَنَّفَقَالَ أَبَانٌ سَمِعْتُ عُثْمَانَ بْنَ عَفَّانَ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَنْكِحُ الْمُحْرِمُ وَلاَ يُنْكَحُ وَلاَ يَخْطُبُ  

Umar b. Ubaidullah b. Ma'mar sent me to Aban b. Uthman as he wanted to make the proposal of the marriage of his son with the daughter of Shaiba b. Uthman. He (Aban b. Uthman) was at that time (busy) in the season of Pilgrimage. He said: I deem him to be a man of the desert (for it is a common thing) that a Muhrim can neither marry, nor is he allowed to be married to anyone. It is Uthman (b. Affan) who reported this to us from Messenger of Allah ﷺ.  

حَدَّثَنِي نُبَيْهُ بْنُ وَهْبٍ قَالَ بَعَثَنِي عُمَرُ بْنُ عُبَيْدِ اللَّهِ بْنِ مَعْمَرٍ وَكَانَ يَخْطُبُ بِنْتَ شَيْبَةَ بْنِ عُثْمَانَ عَلَى ابْنِهِ فَأَرْسَلَنِي إِلَى أَبَانِ بْنِ عُثْمَانَ وَهُوَ عَلَى الْمَوْسِمِ فَقَالَ أَلاَ أُرَاهُ أَعْرَابِيًّا إِنَّ الْمُحْرِمَ لاَ يَنْكِحُ وَلاَ يُنْكَحُ أَخْبَرَنَا بِذَلِكَ عُثْمَانُ عَنْ رَسُولِ اللَّهِ ﷺ  

A Muhrim should neither marry himself, nor should he be got married to anyone, nor should he make the proposal of marriage.  

عَنْ نُبَيْهِ بْنِ وَهْبٍ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ عُثْمَانَ بْنِ عَفَّانَ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَنْكِحُ الْمُحْرِمُ وَلاَ يُنْكَحُ وَلاَ يَخْطُبُ  

A Muhrim should neithermarry (in that state) nor make the proposal of marriage.  

عَنْ نُبَيْهِ بْنِ وَهْبٍ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ عُثْمَانَ يَبْلُغُ بِهِ النَّبِيَّ ﷺ قَالَ الْمُحْرِمُ لاَ يَنْكِحُ وَلاَ يَخْطُبُ  

I intend to marry Talha b. 'Umar and I earnestly desire you to be present there (in this ceremony of marriage). Aban said to him: I find you a block-headed 'Iraqi. I heard 'Uthman b. 'Affan say that Messenger of Allah ﷺ said: A Muhrim should not marry.  

عَنْ نُبَيْهِ بْنِ وَهْبٍ أَنَّ عُمَرَ بْنَ عُبَيْدِ اللَّهِ بْنِ مَعْمَرٍ أَرَادَ أَنْ يُنْكِحَ ابْنَهُ طَلْحَةَ بِنْتَ شَيْبَةَ بْنِ جُبَيْرٍ فِي الْحَجِّ وَأَبَانُ بْنُ عُثْمَانَ يَوْمَئِذٍ أَمِيرُ الْحَاجِّ فَأَرْسَلَ إِلَى أَبَانٍ إِنِّي قَدْ أَرَدْتُ أَنْ أُنْكِحَ طَلْحَةَ بْنَ عُمَرَ فَأُحِبُّ أَنْ تَحْضُرَ ذَلِكَ فَقَالَ لَهُ أَبَانٌ أَلاَ أُرَاكَ عِرَاقِيًّا جَافِيًا إِنِّي سَمِعْتُ عُثْمَانَ بْنَ عَفَّانَ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَنْكِحُ الْمُحْرِمُ  

" 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."  

أَخْبَرَهُ أَنَّ النَّبِيَّ ﷺ تَزَوَّجَ مَيْمُونَةَ وَهُوَ مُحْرِمٌ زَادَ ابْنُ نُمَيْرٍ فَحَدَّثْتُ بِهِ الزُّهْرِيَّ فَقَالَ أَخْبَرَنِي يَزِيدُ بْنُ الأَصَمِّ أَنَّهُ نَكَحَهَا وَهُوَ حَلاَلٌ  

Messenger of Allah. ﷺ married Maimuna while he was a Muhrim.  

أَنَّهُ قَالَ تَزَوَّجَ رَسُولُ اللَّهِ ﷺ مَيْمُونَةَ وَهُوَ مُحْرِمٌ  

Maimuna daughter of al-Harith narrated to me that Messenger of Allah ﷺ married her and he was not in the state of Ihram. And she (Maimuna) was my mother's sister and that of Ibn 'Abbas (Allah be pleased with them).  

أَنَّ رَسُولَ اللَّهِ ﷺ تَزَوَّجَهَا وَهُوَ حَلاَلٌ قَالَ وَكَانَتْ خَالَتِي وَخَالَةَ ابْنِ عَبَّاسٍ
