In this ayah, Allah is telling His Messenger that he may marry whom he wishes and separate from whom he wishes. Yet, he didn’t marry anyone after this ayah.
“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.”
