فَإِنْ عُثِرَ عَلَىٰ أَنَّهُمَا اسْتَحَقَّا إِثْمًا فَآخَرَانِ يَقُومَانِ مَقَامَهُمَا مِنَ الَّذِينَ اسْتَحَقَّ عَلَيْهِمُ الْأَوْلَيَانِ فَيُقْسِمَانِ بِاللَّهِ لَشَهَادَتُنَا أَحَقُّ مِن شَهَادَتِهِمَا وَمَا اعْتَدَيْنَا إِنَّا إِذًا لَّمِنَ الظَّالِمِينَ (107)
(5:107) Then if it is discovered later that the two are guilty of such sin, then two others shall stand in their place from among those against whom the two had sinfully deposed, and swear by Allah: 'Our testimony is truer than the testimony of the other two, and we have not transgressed in our statement; for then indeed we would become wrong-doers.'
