لَا يَحِلُّ لَكَ النِّسَاء مِن بَعْدُ وَلَا أَن تَبَدَّلَ بِهِنَّ مِنْ أَزْوَاجٍ وَلَوْ أَعْجَبَكَ حُسْنُهُنَّ إِلَّا مَا مَلَكَتْ يَمِينُكَ وَكَانَ اللَّهُ عَلَى كُلِّ شَيْءٍ رَّقِيبًا
﴿٥٢﴾
سورة الأحزاب
(33/52) After this, it is not lawful for you to change (with another woman) one of the (other) women or your wives even though their beauty pleases you, except those (concubines) whom your right hand possesses. And Allah is Watcher over all things.
Surah Al-Ahzab
