Ibn ‘Abbas said The Prophet ﷺ married Maimunah while he was in the sacred state(wearing ihram). (Using translation from Abū Dāʾūd 1844)  

أَنَّ النَّبِيَّ ﷺ «تَزَوَّجَ مَيْمُونَةَ وَهُوَ مُحْرِمٌ»  

[Machine] "The Messenger of Allah ﷺ married some of his wives while he was in a state of ihram."  

«تَزَوَّجَ رَسُولُ اللهِ ﷺ بَعْضَ نِسَائِهِ وَهُوَ مُحْرِمٌ»  

[Machine] "From Abu Asim, who is noble, from Uthman ibn Aswad, from Ibn Abi Mulayka, from Aisha, that the Messenger of Allah ﷺ married while he was in a state of ihram (i.e., during the pilgrimage). I said to Abu Asim, 'You have added this to us from your own fabrication, as Aisha is not mentioned in it.' He said, 'Leave Aisha aside, let me verify it.'"  

عَنْ أَبِي عَاصِمٍ هُوَ النَّبِيلُ عَنْ عُثْمَانَ بْنِ الْأَسْوَدِ عَنِ ابْنِ أَبِي مُلَيْكَةَ عَنْ عَائِشَةَ أَنَّ رَسُولَ اللهِ ﷺ «تَزَوَّجَ وَهُوَ مُحْرِمٌ» قُلْتُ لِأَبِي عَاصِمٍ أَنْتَ أَمْلَيْتَ عَلَيْنَا هَذَا مِنَ الرُّقْعَةِ لَيْسَ فِيهِ عَائِشَةُ فَقَالَ دَعْ عَائِشَةَ حَتَّى أَنْظُرَ فِيهِ  

"The Messenger of Allah married Maimunah bint Al-Harith when he was a Muhrim." According to the Hadith of Ya'la (one of the narrators): "In Sarif." (Using translation from Nasāʾī 3271)  

«تَزَوَّجَ رَسُولُ اللهِ ﷺ مَيْمُونَةَ بِنْتَ الْحَارِثِ وَهُوَ مُحْرِمٌ» وَفِي حَدِيثِ يَعْلَى بِسَرِفَ
