Nobel Quran - English Translation
51. Thou mayest put aside any of them that thou pleasest, and keep with thyself whom thou pleasest; and if thou desirest to take back any of those whom thou hast put aside, there is no blame on thee. That is more likely that their eyes may be cooled, and that they may not grieve, and that they may all be pleased with that which thou hast given them. And ALLAH knows what is in your hearts; and ALLAH is All-Knowing, Forbearing.
52. It is not allowed to thee to marry women after that, nor to change them for other wives even, though their goodness please thee, except any that thy right hand possesses. And ALLAH is Watchful over all things.
53. O ye who believe ! enter not the houses of the Prophet unless leave is granted to you for a meal, not waiting till it is cooked. But enter when you are invited, and when you have had your meal, disperse, without seeking to engage in talk. That causes inconvenience to the Prophet, and he feels shy of asking you to leave, but ALLAH is not shy of saying what is true. And when you ask them - the wives of the Prophet - for anything, ask them from behind a curtain. That is purer for your hearts and their hearts. And it behoves you not to cause inconvenience to the Messenger of ALLAH, nor that you should ever marry his wives after him. That, indeed, is a monstrous thing in the sight of ALLAH.
54. Whether you disclose a thing or conceal it, ALLAH knows all things well.
