The Book of Divorce (Kitab Al-Talaq)
Muslim :: Book 9 : Hadith 3499
'A'isha (Allah be pleased with her) reported that Allah's Messenger (may peace be upon him) sought our permission when he had a (turn to spend) a day with (one of his wives) amongst us (whereas he wanted to visit his other wives too). It was after this that this verse was revealed:" Thou mayest put off whom thou pleasest of them, and take for thee whom thou pleasest" (xxxiii. 5). Mu'adha said to her: What did you say to Allah's Messenger (may peace be upon him) when he sought your permission? She said: I used to say: If it had the option in this I would not have (allowed anyone) to have precedence over me.
