﴿ 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,”

(Save from their wives) up to four wives (or the (slaves) that their right hands possess) without any limit in number, (for then they are not blameworthy) when they engage in that which is lawful,
