حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّهَا كَانَتْ تَقُولُ أَمَا تَسْتَحِي الْمَرْأَةُ أَنْ تَهَبَ نَفْسَهَا لِلنَّبِيِّ ـ صلى الله عليه وسلم ـ حَتَّى أَنْزَلَ اللَّهُ ‏{تُرْجِي مَنْ تَشَاءُ مِنْهُنَّ وَتُؤْوِي إِلَيْكَ مَنْ تَشَاءُ}‏ ‏.‏ قَالَتْ فَقُلْتُ إِنَّ رَبَّكَ لَيُسَارِعُ فِي هَوَاكَ ‏.‏

It 'was narrated from Hisham bin 'Urwah, from his father that 'Aishah used to say: "Wouldn't a woman feel too shy to offer herself to the Prophet?" Until Aileh revealed; "You (O Muhammad) can postpone (the turn of) whom you will of them (your wives), and you may receive whom you will.” She said: "Then I said: 'Your Lord is quick to make things easy for you."'
