The Book of Divorce
18/4. Chapter:
Giving one's wife the choice does not count as a divorce, unless it is intended as such
Sahih Muslim
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَاصِمٍ، عَنِ الشَّعْبِيِّ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم خَيَّرَ نِسَاءَهُ فَلَمْ يَكُنْ طَلاَقًا.
'A'isha reported that Allah's Messenger (ﷺ) gave option to his wives, but it was not a divorce.
