And when you divorce women and they have fulfilled their term, do not prevent them from remarrying their ˹former˺ husbands if they agree among themselves on an acceptable basis. That is instructed to whoever of you believes in Allah and the Last Day. That is better for you and purer, and Allah knows and you know not.  

وَإِذَا طَلَّقْتُمُ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَنْ يَنْكِحْنَ أَزْوَاجَهُنَّ إِذَا تَرَاضَوْا بَيْنَهُمْ بِالْمَعْرُوفِ ۗ ذَٰلِكَ يُوعَظُ بِهِ مَنْ كَانَ مِنْكُمْ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ ۗ ذَٰلِكُمْ أَزْكَىٰ لَكُمْ وَأَطْهَرُ ۗ وَاللَّهُ يَعْلَمُ وَأَنْتُمْ لَا تَعْلَمُونَ  

[Machine] To return her, but if he prevents her, a place of refuge has been set up for her. And Allah the Exalted says, "And when you divorce women and they have fulfilled their term, do not prevent them from remarrying their [former] husbands if they agree among themselves on an acceptable basis." [Al-Baqarah 2:232]  

أَنْ يُرَاجِعَهَا فَمَنَعَهَا مَعْقِلٌ فَأَنْزَلَ اللَّهُ تَعَالَى {وَإِذَا طَلَّقْتُمُ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَنْ يَنْكِحْنَ أَزْوَاجَهُنَّ إِذَا تَرَاضَوْا بَيْنَهُمْ بِالْمَعْرُوفِ} [البقرة 232]  

[Machine] His sister was under a man, then he divorced her and kept away from her until her waiting period expired. Then he approached to propose to her, but a fortification prevented him from it, and he said, "He kept away from her while he was able to marry her." So, something happened between him and her, and Allah revealed (And when you divorce women and they have fulfilled their term, do not prevent them from remarrying their [former] husbands if they agree among themselves on an acceptable basis) [Quran 2:232].  

كَانَتْ أُخْتُهُ تَحْتَ رَجُلٍ فَطَلَّقَهَا ثُمَّ خَلَّى عَنْهَا حَتَّى انْقَضَتْ عِدَّتُهَا ثُمَّ قَرَّبَ يَخْطُبُهَا فَحَمِيَ مَعْقِلٌ مِنْ ذَلِكَ وَقَالَ خَلَّى عَنْهَا وَهُوَ يَقْدِرُ عَلَيْهَا فَحَالَ بَيْنَهُ وَبَيْنَهَا فَأَنْزَلَ اللَّهُ {وَإِذَا طَلَّقْتُمِ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَنْ يَنْكِحْنَ أَزْوَاجَهُنَّ إِذَا تَرَاضَوْا بَيْنَهُمْ بِالْمَعْرُوفِ}
