Quran 24, An-Nur (Light) ⓘ

24:2The adulterer and the adulteress, scourge ye each one of them (with) a hundred stripes. And let not pity for the twain withhold you from obedience to Allah, if ye believe in Allah and the Last Day. And let a party of believers witness their punishment.

الزَّانِيَةُ وَالزَّانِي فَاجْلِدُوا كُلَّ وَاحِدٍ مِنْهُمَا مِائَةَ جَلْدَةٍ وَلَا تَأْخُذْكُمْ بِهِمَا رَأْفَةٌ فِي دِينِ اللَّهِ إِنْ كُنْتُمْ تُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَلْيَشْهَدْ عَذَابَهُمَا طَائِفَةٌ مِنَ الْمُؤْمِنِينَ
