Al-Ahzab 33:51

۞تُرۡجِي مَن تَشَآءُ مِنۡهُنَّ وَتُـٔۡوِيٓ إِلَيۡكَ مَن تَشَآءُۖ وَمَنِ ٱبۡتَغَيۡتَ مِمَّنۡ عَزَلۡتَ فَلَا جُنَاحَ عَلَيۡكَۚ ذَٰلِكَ أَدۡنَىٰٓ أَن تَقَرَّ أَعۡيُنُهُنَّ وَلَا يَحۡزَنَّ وَيَرۡضَيۡنَ بِمَآ ءَاتَيۡتَهُنَّ كُلُّهُنَّۚ وَٱللَّهُ يَعۡلَمُ مَا فِي قُلُوبِكُمۡۚ وَكَانَ ٱللَّهُ عَلِيمًا حَلِيمٗا 51

You, [O Muhammad], may put aside whom you will of them or take to yourself whom you will. And any that you desire of those [wives] from whom you had [temporarily] separated - there is no blame upon you [in returning her]. That is more suitable that they should be content and not grieve and that they should be satisfied with what you have given them - all of them. And Allah knows what is in your hearts. And ever is Allah Knowing and Forbearing
