The root خ ر ص (kh-r-ṣ) in the Quran

وَإِن تُطِعْ أَكْثَرَ مَن فِى ٱلْأَرْضِ يُضِلُّوكَ عَن سَبِيلِ ٱللَّهِ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ هُمْ إِلَّا يَخْرُصُونَ ۝١١٦

And if you obey most of those upon the earth, they will mislead you from the way of Allāh. They follow not except assumption, and they are not but misjudging.

سَيَقُولُ ٱلَّذِينَ أَشْرَكُوا۟ لَوْ شَآءَ ٱللَّهُ مَآ أَشْرَكْنَا وَلَآ ءَابَآؤُنَا وَلَا حَرَّمْنَا مِن شَىْءٍ كَذَٰلِكَ كَذَّبَ ٱلَّذِينَ مِن قَبْلِهِمْ حَتَّىٰ ذَاقُوا۟ بَأْسَنَا قُلْ هَلْ عِندَكُم مِّنْ عِلْمٍ فَتُخْرِجُوهُ لَنَآ إِن تَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ أَنتُمْ إِلَّا تَخْرُصُونَ ۝١٤٨

Those who associated [others] with Allāh will say, "If Allāh had willed, we would not have associated [anything] and neither would our fathers, nor would we have prohibited anything." Likewise did those before deny until they tasted Our punishment. Say, "Do you have any knowledge that you can produce for us? You follow not except assumption, and you are not but misjudging."

أَلَآ إِنَّ لِلَّهِ مَن فِى ٱلسَّمَٰوَٰتِ وَمَن فِى ٱلْأَرْضِ وَمَا يَتَّبِعُ ٱلَّذِينَ يَدْعُونَ مِن دُونِ ٱللَّهِ شُرَكَآءَ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ هُمْ إِلَّا يَخْرُصُونَ ۝٦٦

Unquestionably, to Allāh belongs whoever is in the heavens and whoever is on the earth. And those who invoke other than Allāh do not [actually] follow [His] "partners." They follow not except assumption, and they are not but misjudging.

وَقَالُوا۟ لَوْ شَآءَ ٱلرَّحْمَٰنُ مَا عَبَدْنَٰهُم مَّا لَهُم بِذَٰلِكَ مِنْ عِلْمٍ إِنْ هُمْ إِلَّا يَخْرُصُونَ ۝٢٠

And they said, "If the Most Merciful had willed, we would not have worshipped them." They have of that no knowledge. They are not but misjudging.

قُتِلَ ٱلْخَرَّٰصُونَ ۝١٠

Destroyed are the misinformers
