﴿فَإِنْ عُثِرَ عَلَىٰٓ أَنَّهُمَا ٱسْتَحَقَّآ إِثْمًا فَـَٔاخَرَانِ يَقُومَانِ مَقَامَهُمَا مِنَ ٱلَّذِينَ ٱسْتَحَقَّ عَلَيْهِمُ ٱلْأَوْلَيَٰنِ فَيُقْسِمَانِ بِٱللَّهِ لَشَهَٰدَتُنَآ أَحَقُّ مِن شَهَٰدَتِهِمَا وَمَا ٱعْتَدَيْنَآ إِنَّآ إِذًا لَّمِنَ ٱلظَّٰلِمِينَ﴾

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."

Surah Al-Kahf : 21 Meccan

﴿وَكَذَٰلِكَ أَعْثَرْنَا عَلَيْهِمْ لِيَعْلَمُوٓا۟ أَنَّ وَعْدَ ٱللَّهِ حَقٌّ وَأَنَّ ٱلسَّاعَةَ لَا رَيْبَ فِيهَآ إِذْ يَتَنَٰزَعُونَ بَيْنَهُمْ أَمْرَهُمْ فَقَالُوا۟ ٱبْنُوا۟ عَلَيْهِم بُنْيَٰنًا رَّبُّهُمْ أَعْلَمُ بِهِمْ قَالَ ٱلَّذِينَ غَلَبُوا۟ عَلَىٰٓ أَمْرِهِمْ لَنَتَّخِذَنَّ عَلَيْهِم مَّسْجِدًا﴾

And similarly, We caused them to be found that they [who found them] would know that the promise of Allah is truth and that of the Hour there is no doubt. [That was] when they disputed among themselves about their affair and [then] said, "Construct over them a structure. Their Lord is most knowing about them." Said those who prevailed in the matter, "We will surely take [for ourselves] over them a masjid."
