quran:17:32 –

And do not approach unlawful sexual intercourse. Indeed, it is ever an immorality and is evil as a way.  

And do not come ˹anywhere˺ near fornication — this ˹form of expressing it˺ is more effective than ˹saying˺ ‘Do not commit it’. It is indeed an indecency, an abomination, and, it is, an evil way.
القرآن:١٧:٣٢ –

وَلَا تَقْرَبُوا الزِّنَىٰ ۖ إِنَّهُ كَانَ فَاحِشَةً وَسَاءَ سَبِيلًا  

{ولا تقربوا الزنى} أبلغ من لا تأتوه {إنه كان فاحشة} قبيحا {وساء} بئس {سبيلاً} طريقا هو.
