Surah Al-Baqarah, verse 229

وَإِنْ عَزَمُوا۟ ٱلطَّلَـٰقَ فَإِنَّ ٱللَّهَ سَمِيعٌ عَلِيمٌۭ ﴿٢٢٧﴾

And if they decide on divorce - then indeed, Allāh is Hearing and Knowing.

وَٱلْمُطَلَّقَـٰتُ يَتَرَبَّصْنَ بِأَنفُسِهِنَّ ثَلَـٰثَةَ قُرُوٓءٍۢ ۚ وَلَا يَحِلُّ لَهُنَّ أَن يَكْتُمْنَ مَا خَلَقَ ٱللَّهُ فِىٓ أَرْحَامِهِنَّ إِن كُنَّ يُؤْمِنَّ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ۚ وَبُعُولَتُهُنَّ أَحَقُّ بِرَدِّهِنَّ فِى ذَٰلِكَ إِنْ أَرَادُوٓا۟ إِصْلَـٰحًۭا ۚ وَلَهُنَّ مِثْلُ ٱلَّذِى عَلَيْهِنَّ بِٱلْمَعْرُوفِ ۚ وَلِلرِّجَالِ عَلَيْهِنَّ دَرَجَةٌۭ ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌ ﴿٢٢٨﴾

Divorced women remain in waiting [i.e., do not remarry] for three periods, and it is not lawful for them to conceal what Allāh has created in their wombs if they believe in Allāh and the Last Day. And their husbands have more right to take them back in this [period] if they want reconciliation. And due to them [i.e., the wives] is similar to what is expected of them, according to what is reasonable. But the men [i.e., husbands] have a degree over them [in responsibility and authority]. And Allāh is Exalted in Might and Wise.

فَإِن طَلَّقَهَا فَلَا تَحِلُّ لَهُۥ مِنۢ بَعْدُ حَتَّىٰ تَنكِحَ زَوْجًا غَيْرَهُۥ ۗ فَإِن طَلَّقَهَا فَلَا جُنَاحَ عَلَيْهِمَآ أَن يَتَرَاجَعَآ إِن ظَنَّآ أَن يُقِيمَا حُدُودَ ٱللَّهِ ۗ وَتِلْكَ حُدُودُ ٱللَّهِ يُبَيِّنُهَا لِقَوْمٍۢ يَعْلَمُونَ ﴿٢٣٠﴾

And if he has divorced her [for the third time], then she is not lawful to him afterward until [after] she marries a husband other than him. And if he [i.e., the latter husband] divorces her [or dies], there is no blame upon them [i.e., the woman and her former husband] for returning to each other if they think that they can keep [within] the limits of Allāh. These are the limits of Allāh, which He makes clear to a people who know [i.e.,understand].

وَإِذَا طَلَّقْتُمُ ٱلنِّسَآءَ فَبَلَغْنَ أَجَلَهُنَّ فَأَمْسِكُوهُنَّ بِمَعْرُوفٍ أَوْ سَرِّحُوهُنَّ بِمَعْرُوفٍۢ ۚ وَلَا تُمْسِكُوهُنَّ ضِرَارًۭا لِّتَعْتَدُوا۟ ۚ وَمَن يَفْعَلْ ذَٰلِكَ فَقَدْ ظَلَمَ نَفْسَهُۥ ۚ وَلَا تَتَّخِذُوٓا۟ ءَايَـٰتِ ٱللَّهِ هُزُوًۭا ۚ وَٱذْكُرُوا۟ نِعْمَتَ ٱللَّهِ عَلَيْكُمْ وَمَآ أَنزَلَ عَلَيْكُم مِّنَ ٱلْكِتَـٰبِ وَٱلْحِكْمَةِ يَعِظُكُم بِهِۦ ۚ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌۭ ﴿٢٣١﴾

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.
