Sahih al-Bukhari, Hadith 5263 ⓘ
Narrated Masruq: I asked `Aisha about the option: She said, "The Prophet gave us the option. Do you think that option was considered as a divorce?" I said, "It matters little to me if I give my wife the option once or a hundred times after she has chosen me."
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ إِسْمَاعِيلَ، حَدَّثَنَا عَامِرٌ، عَنْ مَسْرُوقٍ، قَالَ سَأَلْتُ عَائِشَةَ عَنِ الْخِيَرَةِ،، فَقَالَتْ خَيَّرَنَا النَّبِيُّ صلى الله عليه وسلم أَفَكَانَ طَلاَقًا قَالَ مَسْرُوقٌ لاَ أُبَالِي أَخَيَّرْتُهَا وَاحِدَةً أَوْ مِائَةً بَعْدَ أَنْ تَخْتَارَنِي.
