Sunan an-Nasa'i 3407
It was narrated that 'Aishah said:
"The Messenger of Allah was asked about a man who divorced his wife, and she married another man who had a closed meeting with her then divorced her, before having intercourse with her. Is it permissible for her to remarry the first husband? The Messenger of Allah said: 'No, not until the second one tastes her sweetness and she tastes his sweetness.'"
أَخْبَرَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ سُئِلَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ رَجُلٍ طَلَّقَ امْرَأَتَهُ فَتَزَوَّجَتْ زَوْجًا غَيْرَهُ فَدَخَلَ بِهَا ثُمَّ طَلَّقَهَا قَبْلَ أَنْ يُوَاقِعَهَا أَتَحِلُّ لِلأَوَّلِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ لاَ حَتَّى يَذُوقَ الآخَرُ عُسَيْلَتَهَا وَتَذُوقَ عُسَيْلَتَهُ ‏"‏ ‏.‏
