﴿ 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,”

except from their wives and those whom their right hands own in the way of slavegirls for in that case they are not blameworthy;
