In-book no 5053حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، حَدَّثَنَا مُسْلِمٌ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ خَيَّرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم فَاخْتَرْنَا اللَّهَ وَرَسُولَهُ، فَلَمْ يَعُدَّ ذَلِكَ عَلَيْنَا شَيْئًا.
Narrated `Aisha: Allah's Messenger (ﷺ) gave us the option (to remain with him or to be divorced) and we selected Allah and His Apostle . So, giving us that option was not regarded as divorce.
