الزَّانِيَةُ وَالزَّانِي فَاجْلِدُوا كُلَّ وَاحِدٍ مِّنْهُمَا مِئَةَ جَلْدَةٍ وَلَا تَأْخُذْكُم بِهِمَا رَأْفَةٌ فِي دِينِ اللَّهِ إِن كُنتُمْ تُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَلْيَشْهَدْ عَذَابَهُمَا طَائِفَةٌ مِّنَ

o الْمُؤْمِنِينَ

Translation :

To the woman and the man guilty of illegal sexual relationship, flog each of them with one hundred stripes: let not compassion withhold you in their case, in a matter of punishment prescribed by Allah, if you believe in Allah and the Last Day: and let a party of the believers witness their punishment.
