An-Nur
سُورَةٌ أَنزَلۡنَٰهَا وَفَرَضۡنَٰهَا وَأَنزَلۡنَا فِيهَآ ءَايَٰتِۭ بَيِّنَٰتٖ لَّعَلَّكُمۡ تَذَكَّرُونَ
(This is) a Surah (chapter of the Quran) which We have sent down and which We have enjoined, (ordained its legal laws) and in it We have revealed manifest Ayat (proofs, evidences, verses, lessons, signs, revelations lawful and unlawful things, and set boundries of Islamic Religion), that you may remember.
ٱلزَّانِيَةُ وَٱلزَّانِي فَٱجۡلِدُواْ كُلَّ وَٰحِدٖ مِّنۡهُمَا مِاْئَةَ جَلۡدَةٖۖ وَلَا تَأۡخُذۡكُم بِهِمَا رَأۡفَةٞ فِي دِينِ ٱللَّهِ إِن كُنتُمۡ تُؤۡمِنُونَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِۖ وَلۡيَشۡهَدۡ عَذَابَهُمَا طَآئِفَةٞ مِّنَ ٱلۡمُؤۡمِنِينَ
The woman and the man guilty of illegal sexual intercourse, flog each of them with a hundred stripes. Let not pity withhold you in their case, in a punishment prescribed by Allah, if you believe in Allah and the Last Day. And let a party of the believers witness their punishment. (This punishment is for unmarried persons guilty of the above crime but if married persons commit it, the punishment is to stone them to death, according to Allah's Law).
ٱلزَّانِي لَا يَنكِحُ إِلَّا زَانِيَةً أَوۡ مُشۡرِكَةٗ وَٱلزَّانِيَةُ لَا يَنكِحُهَآ إِلَّا زَانٍ أَوۡ مُشۡرِكٞۚ وَحُرِّمَ ذَٰلِكَ عَلَى ٱلۡمُؤۡمِنِينَ
The adulterer marries not but an adulteress or a Mushrikah and the adulteress none marries her except an adulterer or a Muskrik [and that means that the man who agrees to marry (have a sexual relation with) a Mushrikah (female polytheist, pagan or idolatress) or a prostitute, then surely he is either an adulterer, or a Mushrik (polytheist, pagan or idolater, etc.) And the woman who agrees to marry (have a sexual relation with) a Mushrik (polytheist, pagan or idolater) or an adulterer, then she is either a prostitute or a Mushrikah (female polytheist, pagan, or idolatress, etc.)]. Such a thing is forbidden to the believers (of Islamic Monotheism).
