﴿ وَتَذَرُونَ مَا خَلَقَ لَكُمْ رَبُّكُم مِّنْ أَزْوَٰجِكُم ۚ بَلْ أَنتُمْ قَوْمٌ عَادُونَ ﴾

“keeping yourselves aloof from all the [lawful] spouses whom your Sustainer has created for you? Nay, but you are people who transgress all bounds of what is right!””

and forsake the wives your Lord has created for you? in other words you forsake intimacy with their front parts? Nay but you are a transgressing folk’ overstepping the bounds of what is lawful into what is unlawful.
