"The Prophet married Maimunah when he was in Ihram." (Using translation from Nasāʾī 2837)   

«تَزَوَّجَ النَّبِيُّ ﷺ وَهُوَ مُحْرِمٌ»  

[Machine] About Nubayh ibn Wahb that a man from the Quraysh proposed to Aban ibn Uthman and he was the leader of Al-Mawsim. Aban said, "I only see him as an impoverished man from Iraq. Indeed, the one who is in the state of ihram neither marries nor is he married." Uthman informed us about that from the Messenger of Allah. Abu Muhammad was asked, "Do you agree with this?" He said, "Yes."  

عَنْ نُبَيْهِ بْنِ وَهْبٍ أَنَّ رَجُلًا مِنْ قُرَيْشٍ خَطَبَ إِلَى أَبَانَ بْنِ عُثْمَانَ وَهُوَ أَمِيرُ الْمَوْسِمِ فَقَالَ أَبَانُ لَا أُرَاهُ إِلَّا عِرَاقِيًّا جَافِيًا «إِنَّ الْمُحْرِمَ لَا يَنْكِحُ وَلَا يُنْكِحُ» أَخْبَرَنَا بِذَلِكَ عُثْمَانُ عَنْ رَسُولِ اللَّهِ ﷺ سُئِلَ أَبُو مُحَمَّد تَقُولُ بِهَذَا؟ قَالَ «نَعَمْ»  

Yazid bin Al Asamm, Maimunah’s nephew said on Maimunah’s authority The Apostle of Allaah ﷺ married me when we were not in the sacred state at Sarif. (Using translation from Abū Dāʾūd 1843)   

«تَزَوَّجَنِي رَسُولُ اللَّهِ ﷺ وَنَحْنُ حَلَالَانِ بَعْدَمَا رَجَعَ مِنْ مَكَّةَ بِسَرِفَ»  

"The Messenger of Allah married Maimunah while he was Halal, and he stayed with her while he was Halal, and I was the messenger between the two of them." (Using translation from Tirmidhī 841)   

«تَزَوَّجَ رَسُولُ اللَّهِ ﷺ مَيْمُونَةَ حَلَالًا وَبَنَى بِهَا حَلَالًا وَكُنْتُ الرَّسُولَ بَيْنَهُمَا»
