Surah Al-Ahzab, ayah 52

لَّا يَحِلُّ لَكَ ٱلنِّسَآءُ مِنۢ بَعۡدُ وَلَآ أَن تَبَدَّلَ بِهِنَّ مِنۡ أَزۡوَٰجٖ وَلَوۡ أَعۡجَبَكَ حُسۡنُهُنَّ إِلَّا مَا مَلَكَتۡ يَمِينُكَۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَيۡءٖ رَّقِيبٗا ٥٢

Llā yahillu lakan-nisā'u mim ba'du walā an tabaddala bihinna min azwājin walaw a'jabaka husnuhunna illā mā malakat yamīnuka wakānallāhu 'alā kulli shay'ir raqībā

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.¹²⁰⁷
