betrayal and treachery

وَلَا تُجَـٰدِلْ عَنِ ٱلَّذِينَ يَخْتَانُونَ أَنفُسَهُمْ ۚ إِنَّ ٱللَّهَ لَا يُحِبُّ مَن كَانَ خَوَّانًا أَثِيمًا

And do not argue on behalf of those who deceive themselves. Indeed, Allāh loves not one who is a habitually sinful deceiver.

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَخُونُوا۟ ٱللَّهَ وَٱلرَّسُولَ وَتَخُونُوٓا۟ أَمَـٰنَـٰتِكُمْ وَأَنتُمْ تَعْلَمُونَ

O you who have believed, do not betray Allāh and the Messenger or betray your trusts while you know [the consequence].

لَوْ خَرَجُوا۟ فِيكُم مَّا زَادُوكُمْ إِلَّا خَبَالًا وَلَأَوْضَعُوا۟ خِلَـٰلَكُمْ يَبْغُونَكُمُ ٱلْفِتْنَةَ وَفِيكُمْ سَمَّـٰعُونَ لَهُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلظَّـٰلِمِينَ

Had they gone forth with you, they would not have increased you except in confusion, and they would have been active among you, seeking [to cause] you fitnah [i.e., chaos and dissension]. And among you are avid listeners to them. And Allāh is Knowing of the wrongdoers.
