Sahih al-Bukhari 5262

Arabic

حَدَّثَنَا 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.‏

English translation

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
