hidden enmity

هَـٰٓأَنتُمْ أُو۟لَآءِ تُحِبُّونَهُمْ وَلَا يُحِبُّونَكُمْ وَتُؤْمِنُونَ بِٱلْكِتَـٰبِ كُلِّهِۦ وَإِذَا لَقُوكُمْ قَالُوٓا۟ ءَامَنَّا وَإِذَا خَلَوْا۟ عَضُّوا۟ عَلَيْكُمُ ٱلْأَنَامِلَ مِنَ ٱلْغَيْظِ ۚ قُلْ مُوتُوا۟ بِغَيْظِكُمْ ۗ إِنَّ ٱللَّهَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ

Here you are loving them but they are not loving you, while you believe in the Scripture - all of it. And when they meet you, they say, "We believe." But when they are alone, they bite their fingertips at you in rage. Say, "Die in your rage. Indeed, Allāh is Knowing of that within the breasts."

أَلَمْ تَرَ إِلَى ٱلَّذِينَ نُهُوا۟ عَنِ ٱلنَّجْوَىٰ ثُمَّ يَعُودُونَ لِمَا نُهُوا۟ عَنْهُ وَيَتَنَـٰجَوْنَ بِٱلْإِثْمِ وَٱلْعُدْوَٰنِ وَمَعْصِيَتِ ٱلرَّسُولِ وَإِذَا جَآءُوكَ حَيَّوْكَ بِمَا لَمْ يُحَيِّكَ بِهِ ٱللَّهُ وَيَقُولُونَ فِىٓ أَنفُسِهِمْ لَوْلَا يُعَذِّبُنَا ٱللَّهُ بِمَا نَقُولُ ۚ حَسْبُهُمْ جَهَنَّمُ يَصْلَوْنَهَا ۖ فَبِئْسَ ٱلْمَصِيرُ

Have you not considered those who were forbidden from private conversation [i.e., ridicule and conspiracy] and then return to that which they were forbidden and converse among themselves about sin and aggression and disobedience to the Messenger? And when they come to you, they greet you with that [word] by which Allāh does not greet you and say among themselves, "Why does Allāh not punish us for what we say?" Sufficient for them is Hell, which they will [enter to] burn, and wretched is the destination.
