Sunan an-Nasa'i 3250
It was narrated from Anas that a woman offered herself in marriage to the Prophet. The daughter of Anas laughed and said:
"How little was her modesty." Anas said: "She was better than you; she offered herself in marriage to the Prophet."
أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مَرْحُومٌ، قَالَ حَدَّثَنَا ثَابِتٌ، عَنْ أَنَسٍ، أَنَّ امْرَأَةً، عَرَضَتْ نَفْسَهَا عَلَى النَّبِيِّ صلى الله عليه وسلم فَضَحِكَتِ ابْنَةُ أَنَسٍ فَقَالَتْ مَا كَانَ أَقَلَّ حَيَاءَهَا ‏.‏ فَقَالَ أَنَسٌ هِيَ خَيْرٌ مِنْكِ عَرَضَتْ نَفْسَهَا عَلَى النَّبِيِّ صلى الله عليه وسلم ‏.‏
