Mishkat al-Masabih 3250
‘A’isha said:
Being jealous of the women who offered themselves to God's Messenger I asked, “Does a woman offer herself?” Then when God most high sent down, “You may defer any of them you wish and take to yourself any you wish, and if you desire any you have set aside no sin is chargeable to you” (Al-Qur’an 33:51) said, “It seems to me that your Lord hastens to satisfy your desire.” 

(Bukhari and Muslim.)
وَعَن عَائِشَة قَالَت: كنت أغار من اللَّاتِي وَهَبْنَ أَنْفُسَهُنَّ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقُلْتُ: أَتَهَبُ الْمَرْأَةُ نَفْسَهَا؟ فَلَمَّا أَنْزَلَ اللَّهُ تَعَالَى: (تُرْجِي مَنْ تَشَاءُ مِنْهُنَّ وَتُؤْوِي إِلَيْكَ مَنْ تَشَاءُ وَمَنِ ابْتَغَيْتَ مِمَّنْ عَزَلْتَ فَلَا جنَاح عَلَيْك) قُلْتُ: مَا أَرَى رَبَّكَ إِلَّا يُسَارِعُ فِي هَوَاكَ. مُتَّفَقٌ عَلَيْهِ.
