from the Prophet, concerning a man who had a wife then divorced her, then another man married her but divorced her before consummating the marriage. Could she go back to the first man? He said: “No, not until he tastes her sweetness.” (Using translation from Ibn Mājah 1933)
عَنِ النَّبِيِّ ﷺ فِي الرَّجُلِ تَكُونُ لَهُ الْمَرْأَةُ ثُمَّ يُطَلِّقُهَا ثُمَّ يَتَزَوَّجُهَا رَجُلٌ فَيُطَلِّقُهَا قَبْلَ أَنْ يَدْخُلَ بِهَا فَتَرْجِعُ إِلَى زَوْجِهَا الْأَوَّلِ؟ فَقَالَ رَسُولُ اللهِ ﷺ حَتَّى تَذُوقَ الْعُسَيْلَةَ
