Al-Ahzab 33:52
لَّا يَحِلُّ لَكَ ٱلنِّسَآءُ مِنۢ بَعْدُ وَلَآ أَن تَبَدَّلَ بِهِنَّ مِنْ أَزْوَٰجٍ وَلَوْ أَعْجَبَكَ حُسْنُهُنَّ إِلَّا مَا مَلَكَتْ يَمِينُكَ ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ رَّقِيبًا
La yahillu laka annisaomin baAAdu wala an tabaddala bihinna min azwajinwalaw aAAjabaka husnuhunna illa ma malakatyameenuka wakana Allahu AAala kulli shay-inraqeeba
Not lawful to you, [O Muḥammad], are [any additional] women after [this], nor [is it] for you to exchange them for [other] wives, even if their beauty were to please you, except what your right hand possesses. And ever is Allāh, over all things, an Observer.
No women are lawful for you after this, nor is it lawful that you replace them (the present wives) with other wives, even though their goodness may attract you, except the bond-women you own. And Allah is watchful of every thing.
