فَإِنْ عُثِرَ عَلَىٰٓ أَنَّهُمَا ٱسْتَحَقَّآ إِثْمًا فَـَٔاخَرَانِ يَقُومَانِ مَقَامَهُمَا مِنَ ٱلَّذِينَ ٱسْتَحَقَّ عَلَيْهِمُ ٱلْأَوْلَيَـٰنِ فَيُقْسِمَانِ بِٱللَّهِ لَشَهَـٰدَتُنَآ أَحَقُّ مِن شَهَـٰدَتِهِمَا وَمَا ٱعْتَدَيْنَآ إِنَّآ إِذًا لَّمِنَ ٱلظَّـٰلِمِينَ

But if it is found that those two were guilty of perjury, let two others stand in their place [who are] foremost [in claim] from those who have a lawful right. And let them swear by Allah, "Our testimony is truer than their testimony, and we have not transgressed. Indeed, we would then be of the wrongdoers."
