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 52
It is not lawful for thee (to marry more) women after this, nor to change them for (other) wives, even though their beauty attract thee, except any thy right hand should possess (as handmaidens): and Allah doth watch over all things.
