[Machine] The Messenger of Allah, may peace be upon him, married Maymuna bint al-Harith ibn Frawah. She was the sister of Umm al-Fadl, the wife of Abbas ibn Abdul-Muttalib. He married her when he was performing umrah in Makkah, and she offered herself to the Prophet, may peace be upon him. In her, the verse was revealed: "And a believing woman may offer herself to the Prophet, if the Prophet wishes to marry her - [this is] only for you and not for the believers" (Quran 33:50). Then, she accompanied him to Madinah. Before that, she was with Frawah ibn Abdal Uzza ibn Assad from the Banu Tamim ibn Dawdan tribe. This was mentioned by al-Dhahabi in his summary.  

تَزَوَّجَ رَسُولُ اللَّهِ ﷺ مَيْمُونَةَ بِنْتَ الْحَارِثِ بْنِ فَرْوَةَ وَهِيَ أُخْتُ أُمِّ الْفَضْلِ امْرَأَةِ الْعَبَّاسِ بْنِ عَبْدِ الْمُطَّلِبِ حِينَ اعْتَمَرَ بِمَكَّةَ وَوَهَبَتْ نَفْسَهَا لِلنَّبِيِّ ﷺ وَفِيهَا نَزَلَ {وَامْرَأَةً مُؤْمِنَةً إِنْ وَهَبَتْ نَفْسَهَا لِلنَّبِيِّ إِنْ أَرَادَ النَّبِيُّ أَنْ يَسْتَنْكِحَهَا خَالِصَةً لَكَ مِنْ دُونِ الْمُؤْمِنِينَ} [الأحزاب 50] ثُمَّ صَدَرَتْ مَعَهُ إِلَى الْمَدِينَةِ وَكَانَتْ قَبْلَهُ عِنْدَ فَرْوَةَ بْنِ عَبْدِ الْعُزَّى بْنِ أَسَدٍ مِنْ بَنِي تَمِيمِ بْنِ دُودَانَ حذفه الذهبي من التلخيص
