فَاِنْ عُثِرَ عَلٰۤی اَنَّهُمَا اسْتَحَقَّاۤ اِثْمًا فَاٰخَرٰنِ یَقُوْمٰنِ مَقَامَهُمَا مِنَ الَّذِیْنَ اسْتَحَقَّ عَلَیْهِمُ الْاَوْلَیٰنِ فَیُقْسِمٰنِ بِاللّٰهِ لَشَهَادَتُنَاۤ اَحَقُّ مِنْ شَهَادَتِهِمَا وَمَا اعْتَدَیْنَاۤ اِنَّاۤ اِذًا لَّمِنَ الظّٰلِمِیْنَ ۟

“But if it gets known that these two were guilty of the sin (of perjury), let two others stand forth in their places,- nearest in kin from among those who claim a lawful right: let them swear by Allah: "We affirm that our witness is truer than that of those two, and that we have not trespassed (beyond the truth): if we did, behold! the wrong be upon us!"”
