Appears 5 times in the Quran.

1. 6:116 وَإِن تُطِعْ أَكْثَرَ مَن فِى ٱلْأَرْضِ يُضِلُّوكَ عَن سَبِيلِ ٱللَّهِ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ هُمْ إِلَّا يَخْرُصُونَ

   And if you obey most of those in the earth, they will lead you astray from Allah's way; they follow but conjecture and they only lie.
   

2. 6:148 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

   Those who are polytheists will say: If Allah had pleased we would not have associated (aught with Him) nor our fathers, nor would we have forbidden (to ourselves) anything; even so did those before them reject until they tasted Our punishment. Say: Have you any knowledge with you so you should bring it forth to us? You only follow a conjecture and you only tell lies.
   

3. 10:66 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

   Now, surely, whatever is in the heavens and whatever is in the earth is Allah's; and they do not (really) follow any associates, who call on others besides Allah; they do not follow (anything) but conjectures, and they only lie.
   

4. 43:20 وَقَالُوا۟ لَوْ شَآءَ ٱلرَّحْمَٰنُ مَا عَبَدْنَٰهُم مَّا لَهُم بِذَٰلِكَ مِنْ عِلْمٍ إِنْ هُمْ إِلَّا يَخْرُصُونَ

   And they say: If the Beneficent Allah had pleased, we should never have worshipped them. They have no knowledge of this; they only lie.
   

5. 51:10 قُتِلَ ٱلْخَرَّٰصُونَ

   Cursed be the liars,
