17:32
وَ لَا تَقْرَبُ وا۟ ٱل زِّنَىٰٓ إِنَّ هُۥ كَانَ فَٰحِشَةً وَ سَآءَ سَبِيلًا
And do not approach unlawful sexual intercourse. Indeed, it is ever an immorality and is evil as a way.
24:2
ٱل زَّانِيَةُ وَ ٱل زَّانِى فَ ٱجْلِدُ وا۟ كُلَّ وَٰحِدٍ مِّنْ هُمَا مِا۟ئَةَ جَلْدَةٍ وَ لَا تَأْخُذْ كُم بِ هِمَا رَأْفَةٌ فِى دِينِ ٱللَّهِ إِن كُن تُمْ تُؤْمِنُ ونَ بِ ٱللَّهِ وَ ٱلْ يَوْمِ ٱلْ ءَاخِرِ وَ لْ يَشْهَدْ عَذَابَ هُمَا طَآئِفَةٌ مِّنَ ٱلْ مُؤْمِنِينَ
The [unmarried] woman or [unmarried] man found guilty of sexual intercourse - lash each one of them with a hundred lashes, and do not be taken by pity for them in the religion of Allah, if you should believe in Allah and the Last Day. And let a group of the believers witness their punishment.
24:3
ٱل زَّانِى لَا يَنكِحُ إِلَّا زَانِيَةً أَوْ مُشْرِكَةً وَ ٱل زَّانِيَةُ لَا يَنكِحُ هَآ إِلَّا زَانٍ أَوْ مُشْرِكٌ وَ حُرِّمَ ذَٰلِكَ عَلَى ٱلْ مُؤْمِنِينَ
The fornicator does not marry except a [female] fornicator or polytheist, and none marries her except a fornicator or a polytheist, and that has been made unlawful to the believers.
25:68
وَ ٱلَّذِينَ لَا يَدْعُ ونَ مَعَ ٱللَّهِ إِلَٰهًا ءَاخَرَ وَ لَا يَقْتُلُ ونَ ٱل نَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِ ٱلْ حَقِّ وَ لَا يَزْنُ ونَ وَ مَن يَفْعَلْ ذَٰلِكَ يَلْقَ أَثَامًا
And those who do not invoke with Allah another deity or kill the soul which Allah has forbidden [to be killed], except by right, and do not commit unlawful sexual intercourse. And whoever should do that will meet a penalty.
60:12
يَٰٓ أَيُّهَا ٱل نَّبِىُّ إِذَا جَآءَ كَ ٱلْ مُؤْمِنَٰتُ يُبَايِعْ نَ كَ عَلَىٰٓ أَن لَّا يُشْرِكْ نَ بِ ٱللَّهِ شَيْـًٔا وَ لَا يَسْرِقْ نَ وَ لَا يَزْنِي نَ وَ لَا يَقْتُلْ نَ أَوْلَٰدَ هُنَّ وَ لَا يَأْتِي نَ بِ بُهْتَٰنٍ يَفْتَرِي نَ هُۥ بَيْنَ أَيْدِي هِنَّ وَ أَرْجُلِ هِنَّ وَ لَا يَعْصِي نَ كَ فِى مَعْرُوفٍ فَ بَايِعْ هُنَّ وَ ٱسْتَغْفِرْ لَ هُنَّ ٱللَّهَ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ
O Prophet, when the believing women come to you pledging to you that they will not associate anything with Allah, nor will they steal, nor will they commit unlawful sexual intercourse, nor will they kill their children, nor will they bring forth a slander they have invented between their arms and legs, nor will they disobey you in what is right - then accept their pledge and ask forgiveness for them of Allah. Indeed, Allah is Forgiving and Merciful.
