You, [O Muḥammad], may put aside whom you will of them1 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 Allāh knows what is in your hearts. And ever is Allāh Knowing and Forbearing.
Translation: Saheeh International (English)
1 Those mentioned in the previous verse as being lawful to the Prophet (ﷺ) or his wives to which he was married.
O Messenger! Defer the turn of whichever of your wives you wish to defer by not spending the night with her when it is her turn that you do, and spend the night with whichever of your wives you wish. And there is no sin on you should you wish to spend the night with the one whose turn you deferred. This choice and broadening your options for you is more effective in making you the coolness of the eyes of your wives and in them being pleased with whatever you give all of them, because they know that you have not left out an obligation or have not fulfilled a right. O Men! Allah knows the inclination of your hearts towards some of your wives over others; Allah is the knower of the actions of His servants, nothing from them is hidden from Him. He is also forbearing; He does not punish them immediately in case they repent to Him.
