[In order to relieve you (Mohammad) of the domestic worries so that you could carry out your duties,] Your are granted the option to shun away any of your wives, bring closer to you any one of them and there will be no blame on you, if you reconcile with the ones that you have put aside. It is expected from them to understand [that as the wife of Prophet they cannot expect an ordinary life and] that they will be content with whatever you give them. God knows what is going on in your heart. God knows everything [and due to his knowledge of the situation, He is understanding] and the Most Merciful.
