﴿ إِلَّا عَلَىٰٓ أَزْوَٰجِهِمْ أَوْ مَا مَلَكَتْ أَيْمَٰنُهُمْ فَإِنَّهُمْ غَيْرُ مَلُومِينَ ﴾

“[not giving way to their desires] with any but their spouses - that is, those whom they rightfully possess [through wedlock] -: for then, behold, they are free of all blame,”

قال الفراء: أي من أزواجهم اللاتي أحل الله لهم لا يجاوزون.
