﴿ فَمَنِ ٱبْتَغَىٰ وَرَآءَ ذَٰلِكَ فَأُو۟لَٰٓئِكَ هُمُ ٱلْعَادُونَ ﴾

“whereas such as seek to go beyond that [limit] are truly transgressors;”

But whoever seeks anything beyond that intercourse with wives and concubines such as masturbation those they are transgressors who have overstepped the bounds into what is not lawful for them.
