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. (Using translation from Abū Dāʾūd 2136)

«كَانَ رَسُولُ اللَّهِ ﷺ يَسْتَأْذِنُنَا فِي يَوْمِ الْمَرْأَةِ مِنَّا بَعْدَمَا أُنْزِلَتْ {تُرْجِي مَنْ تَشَاءُ مِنْهُنَّ وَتُؤْوِي} إِلَيْكَ مَنْ تَشَاءُ» قَالَتْ مُعَاذَةُ فَمَا تَقُولِينَ لِرَسُولِ اللَّهِ ﷺ إِذَا اسْتَأْذَنَكِ قَالَتْ أَقُولُ إِنْ كَانَ ذَاكَ إِلَيَّ لَمْ أُوثِرْ أَحَدًا عَلَى نَفْسِي
