Qur'an 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

“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.”
