وَإِذَا طَلَّقْتُمُ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَأَمْسِكُوهُنَّ بِمَعْرُوفٍ أَوْ سَرِّحُوهُنَّ بِمَعْرُوفٍ وَلَا تُمْسِكُوهُنَّ ضِرَارًا لِّتَعْتَدُوا وَمَن يَفْعَلْ ذَٰلِكَ فَقَدْ ظَلَمَ نَفْسَهُ وَلَا تَتَّخِذُوا آيَاتِ اللَّهِ هُزُوًا وَاذْكُرُوا نِعْمَتَ اللَّهِ عَلَيْكُمْ وَمَا أَنزَلَ عَلَيْكُم مِّنَ الْكِتَابِ وَالْحِكْمَةِ يَعِظُكُم بِهِ وَاتَّقُوا اللَّهَ وَاعْلَمُوا أَنَّ اللَّهَ بِكُلِّ شَيْءٍ عَلِيمٌ ٢٣١

يَعِظُكُم yaʿiẓukum · He instructs you

And when you divorce women and they have [nearly] fulfilled their term, either retain them according to acceptable terms or release them according to acceptable terms, and do not keep them, intending harm, to transgress [against them]. And whoever does that has certainly wronged himself. And do not take the verses of Allāh in jest. And remember the favor of Allāh upon you and what has been revealed to you of the Book [i.e., the Qur’ān] and wisdom [i.e., the Prophet's sunnah] by which He instructs you. And fear Allāh and know that Allāh is Knowing of all things. (Surah Al-Baqarah, 2:231)

وَإِذَا طَلَّقْتُمُ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَن يَنكِحْنَ أَزْوَاجَهُنَّ إِذَا تَرَاضَوْا بَيْنَهُم بِالْمَعْرُوفِ ذَٰلِكَ يُوعَظُ بِهِ مَن كَانَ مِنكُمْ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ ذَٰلِكُمْ أَزْكَىٰ لَكُمْ وَأَطْهَرُ وَاللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ ٢٣٢

يُوعَظُ yūʿaẓu · is admonished

And when you divorce women and they have fulfilled their term, do not prevent them from remarrying their [former] husbands if they [i.e., all parties] agree among themselves on an acceptable basis. That is instructed to whoever of you believes in Allāh and the Last Day. That is better for you and purer, and Allāh knows and you know not. (Surah Al-Baqarah, 2:232)

فَجَعَلْنَاهَا نَكَالًا لِّمَا بَيْنَ يَدَيْهَا وَمَا خَلْفَهَا وَمَوْعِظَةً لِّلْمُتَّقِينَ ٦٦

And We made it a deterrent punishment for those who were present and those who succeeded [them] and a lesson for those who fear Allāh. (Surah Al-Baqarah, 2:66)

قَالُوا سَوَاءٌ عَلَيْنَا أَوَعَظْتَ أَمْ لَمْ تَكُن مِّنَ الْوَاعِظِينَ ١٣٦
