Quran 2:232 from Surah Al-Baqara on Divine Marvels.
وَإِذَا طَلَّقۡتُمُ ٱلنِّسَآءَ فَبَلَغۡنَ أَجَلَهُنَّ فَلَا تَعۡضُلُوهُنَّ أَن يَنكِحۡنَ أَزۡوَٰجَهُنَّ إِذَا تَرَٰضَوۡاْ بَيۡنَهُم بِٱلۡمَعۡرُوفِۗ ذَٰلِكَ يُوعَظُ بِهِۦ مَن كَانَ مِنكُمۡ يُؤۡمِنُ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِۗ ذَٰلِكُمۡ أَزۡكَىٰ لَكُمۡ وَأَطۡهَرُۚ وَٱللَّهُ يَعۡلَمُ وَأَنتُمۡ لَا تَعۡلَمُونَ
English translation: And when you divorce [the] women and they reached their (waiting) term then (do) not hinder them [that] (from) marrying their husbands when they agree between themselves in a fair manner That is admonished with it whoever [is] among you believes in Allah and the Day [the] Last that (is) more virtuous for you and more purer And Allah knows and you (do) not know
