Sahih Bukhari Volume 6, Book 65, Hadith 4791

حَدَّثَنَا حِبَّانُ بْنُ مُوسَى، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا عَاصِمٌ الأَحْوَلُ، عَنْ مُعَاذَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَسْتَأْذِنُ فِي يَوْمِ الْمَرْأَةِ مِنَّا بَعْدَ أَنْ أُنْزِلَتْ هَذِهِ الآيَةُ ‏{‏تُرْجِئُ مَنْ تَشَاءُ مِنْهُنَّ وَتُؤْوِي إِلَيْكَ مَنْ تَشَاءُ وَمَنِ ابْتَغَيْتَ مِمَّنْ عَزَلْتَ فَلاَ جُنَاحَ عَلَيْكَ‏}‏‏.‏ فَقُلْتُ لَهَا مَا كُنْتِ تَقُولِينَ قَالَتْ كُنْتُ أَقُولُ لَهُ إِنْ كَانَ ذَاكَ إِلَىَّ فَإِنِّي لاَ أُرِيدُ يَا رَسُولَ اللَّهِ أَنْ أُوثِرَ عَلَيْكَ أَحَدًا‏.‏ تَابَعَهُ عَبَّادُ بْنُ عَبَّادٍ سَمِعَ عَاصِمًا‏.‏

Narrated By Muadha : 'Aisha said, "Allah's Apostle used to take the permission of that wife with whom he was supposed to stay overnight if he wanted to go to one other than her, after this Verse was revealed: "You (O Muhammad) can postpone (the turn of) whom you will of them (your wives) and you may receive any (of them) whom you will; and there is no blame on you if you invite one whose turn you have set aside (temporarily). (33.51) I asked 'Aisha, "What did you use to say (in this case)?" She said, "I used to say to him, "If I could deny you the permission (to go to your other wives) I would not allow your favour to be bestowed on any other person."
