Surah An-Nur — Ayah 9

وَٱلْخَـٰمِسَةُ أَنَّ لَعْنَتَ ٱللَّهِ عَلَيْهِ إِن كَانَ مِنَ ٱلْكَـٰذِبِينَ

And the fifth [oath will be] that the curse of Allah be upon him if he should be among the liars.

وَيَدْرَؤُا۟ عَنْهَا ٱلْعَذَابَ أَن تَشْهَدَ أَرْبَعَ شَهَـٰدَٰتٍۭ بِٱللَّهِ ۙ إِنَّهُۥ لَمِنَ ٱلْكَـٰذِبِينَ

But it will prevent punishment from her if she gives four testimonies [swearing] by Allah that indeed, he is of the liars.

وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ وَأَنَّ ٱللَّهَ تَوَّابٌ حَكِيمٌ

And if not for the favor of Allah upon you and His mercy... and because Allah is Accepting of repentance and Wise.

إِنَّ ٱلَّذِينَ جَآءُو بِٱلْإِفْكِ عُصْبَةٌ مِّنكُمْ ۚ لَا تَحْسَبُوهُ شَرًّا لَّكُم ۖ بَلْ هُوَ خَيْرٌ لَّكُمْ ۚ لِكُلِّ ٱمْرِئٍ مِّنْهُم مَّا ٱكْتَسَبَ مِنَ ٱلْإِثْمِ ۚ وَٱلَّذِى تَوَلَّىٰ كِبْرَهُۥ مِنْهُمْ لَهُۥ عَذَابٌ عَظِيمٌ

Indeed, those who came with falsehood are a group among you. Do not think it bad for you; rather it is good for you. For every person among them is what [punishment] he has earned from the sin, and he who took upon himself the greater portion thereof - for him is a great punishment.
