Rifaʿa Al-Qurazi married a lady and then divorced her whereupon she married another man. She came to the Prophet ﷺ and said that her new husband did not approach her, and that he was completely impotent. The Prophet ﷺ said (to her), "No (you cannot remarry your first husband) till you taste the second husband and he tastes you (i.e. till he consummates his marriage with you).  

عَنِ النَّبِيِّ ﷺ حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا عَبْدَةُ عَنْ هِشَامٍ عَنْ أَبِيهِ عَنْ عَائِشَةَ ؓ أَنَّ رِفَاعَةَ الْقُرَظِيَّ تَزَوَّجَ امْرَأَةً ثُمَّ طَلَّقَهَا فَتَزَوَّجَتْ آخَرَ فَأَتَتِ النَّبِيَّ ﷺ فَذَكَرَتْ لَهُ أَنَّهُ لاَ يَأْتِيهَا وَإِنَّهُ لَيْسَ مَعَهُ إِلاَّ مِثْلُ هُدْبَةٍ فَقَالَ لاَ حَتَّى تَذُوقِي عُسَيْلَتَهُ وَيَذُوقَ عُسَيْلَتَكِ
