AN NUUR — Ayat 6
وَالَّذِينَ يَرْمُونَ أَزْوَاجَهُمْ وَلَمْ يَكُن لَّهُمْ شُهَدَاء إِلَّا أَنفُسُهُمْ فَشَهَادَةُ أَحَدِهِمْ أَرْبَعُ شَهَادَاتٍ بِاللَّهِ إِنَّهُ لَمِنَ الصَّادِقِينَ
And those who accuse their wives [of adultery] and have no witnesses except themselves - then the witness of one of them [shall be] four testimonies [swearing] by Allah that indeed, he is of the truthful.
Tafsir Ibnu Katsir
وَالَّذِينَ يَرْمُونَ أَزْوَجَهُمْ وَلَمْ يَكُنْ لَّهُمْ شُهَدَآءُ إِلاَّ أَنفُسُهُمْ فَشَهَـدَةُ أَحَدِهِمْ أَرْبَعُ شَهَـدَاتٍ بِاللَّهِ إِنَّهُ لَمِنَ الصَّـدِقِينَ - وَالْخَامِسَةُ أَنَّ لَعْنَةَ اللَّهِ عَلَيْهِ إِن كَانَ مِنَ الْكَـذِبِينَ - وَيَدْرَؤُاْ عَنْهَا الْعَذَابَ أَن تَشْهَدَ أَرْبَعَ شَهَادَاتٍ بِاللَّهِ إِنَّهُ لَمِنَ الْكَـذِبِينَ - وَالْخَامِسَةَ أَنَّ غَضَبَ اللَّهِ عَلَيْهَآ إِن كَانَ مِنَ الصَّـدِقِينَ - وَلَوْلاَ فَضْلُ اللَّهِ عَلَيْكُمْ وَرَحْمَتُهُ وَأَنَّ اللَّهَ تَوَّابٌ حَكِيمٌ
6. And for those who accuse their wives, but have no witnesses except themselves, let the testimony of one of them be four testimonies by Allah that he is one of those who speak the truth. 7. And the fifth (testimony); invoking of the curse of Allah on him if he be of those who tell a lie. 8. But she shall avert the punishment from her, if she bears witness four times by Allah, that he is telling a lie. 9. And the fifth; should be that the wrath of Allah be upon her if he speaks the truth. 10. And had it not been for the grace of Allah and His mercy on you! And that Allah is the One Who forgives and accepts repentance, the All-Wise. This Ayah offers a way out for husbands. If a husband has accused his wife but cannot come up with proof, he can swear the Li`an (the oath of condemnation) as Allah commanded. This means that he brings her before the Imam and states what he is accusing her of. The ruler then asks him to swear four times by Allah in front of four witnesses
