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
وَحَدَّثَنِي إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا عَبْدُ الرَّحْمَنِ، عَنْ سُفْيَانَ، عَنْ عَاصِمٍ الأَحْوَلِ، وَإِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ عَنِ الشَّعْبِيِّ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ خَيَّرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم فَاخْتَرْنَاهُ فَلَمْ يَعُدَّهُ طَلاَقًا .
'A'isha (Allah be pleased with her) reported: Allah's Messenger (ﷺ) gave us the option (to get divorce) and we chose him and he did not count it a divorce.
