Al-Ahzab (The Armies of Enemies)

Surah 33 · Verse 52

Women beyond these are not lawful for you, nor (is it lawful) that you should change them for other wives, even if their beauty pleased you, except those whom your right hand possesses, and Allah is Vigilant over everything. (R 6)

لَا يَحِلُّ لَكَ النِّسَاءُ مِنْ بَعْدُ وَلَا أَنْ تَبَدَّلَ بِهِنَّ مِنْ أَزْوَاجٍ وَلَوْ أَعْجَبَكَ حُسْنُهُنَّ إِلَّا مَا مَلَكَتْ يَمِينُكَ ۗ وَكَانَ اللَّهُ عَلَىٰ كُلِّ شَيْءٍ رَقِيبًا
