Sunan an-Nasa'i, Volume 4, Book 26, Hadith 3201 (DarusSalam)

Narrated 'Aishah: It was narrated that 'Aishah said: "I used to feel jealous of those (women) who offered themselves (in marriage) to the Prophet and I said: 'Would a free woman offer herself?' Then Allah, the Mighty and Sublime, revealed: 'You can postpone whom you will of them, and you may receive whom you will.' I said: 'By Allah, I see that your Lord is quick to respond to your wishes.'"

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ الْمُخَرِّمِيُّ، قَالَ حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كُنْتُ أَغَارُ عَلَى اللاَّتِي وَهَبْنَ أَنْفُسَهُنَّ لِلنَّبِيِّ صلى الله عليه وسلم فَأَقُولُ أَوَتَهَبُ الْحُرَّةُ نَفْسَهَا فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{‏ تُرْجِي مَنْ تَشَاءُ مِنْهُنَّ وَتُؤْوِي إِلَيْكَ مَنْ تَشَاءُ ‏}‏ قُلْتُ وَاللَّهِ مَا أَرَى رَبَّكَ إِلاَّ يُسَارِعُ لَكَ فِي هَوَاكَ ‏.‏
