Narrated 'Aishah:
The Messenger of Allah (ﷺ) used to aske our permission on the day he had to stay with one of his wives (by turns) after the following Qur'anic verse was revealed: "You may distance those whom you like, and draw close to those whom you like" [33:51]. The narrator Mu'adhah said: I said to her: What did you say to the Messenger of Allah (ﷺ) ? She said: I used to say: If had an option for that, I would not preferred anyone to myself.
حَدَّثَنَا يَحْيَى بْنُ مَعِينٍ، وَمُحَمَّدُ بْنُ عِيسَى، - الْمَعْنَى - قَالاَ حَدَّثَنَا عَبَّادُ بْنُ عَبَّادٍ، عَنْ عَاصِمٍ، عَنْ مُعَاذَةَ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَسْتَأْذِنُنَا إِذَا كَانَ فِي يَوْمِ الْمَرْأَةِ مِنَّا بَعْدَ مَا نَزَلَتْ ‏{‏ تُرْجِي مَنْ تَشَاءُ مِنْهُنَّ وَتُؤْوِي إِلَيْكَ مَنْ تَشَاءُ ‏}‏ قَالَتْ مُعَاذَةُ فَقُلْتُ لَهَا مَا كُنْتِ تَقُولِينَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم قَالَتْ كُنْتُ أَقُولُ إِنْ كَانَ ذَلِكَ إِلَىَّ لَمْ أُوثِرْ أَحَدًا عَلَى نَفْسِي ‏.‏
